    ABSTRACT

    The ketogenic diet, despite its current popularity, was initially developed to address seizure disorders. Its reliance on high fat, moderate protein, low carbohydrate intake can make it a challenge for patient adherence. By maintaining a constant state of ketogenesis from eating fatty foods, patients on the ketogenic diet change their natural fuel source from glucose to ketone bodies. Its medical uses include obesity, glaucoma, diabetes, seizures, and other neurode-
    generative disorders. A key concept is that patients must strive for ketosis (notketoacidosis) and monitor medical conditions closely. It is contraindicated in patients with liver failure, pancreatitis, inborn disorders of fat metabolism, primarycarnitine deficiency, carnitine palmitoyl transferase deficiency, carnitine translocase deficiency, porphyria, and pyruvate kinase deficiency. People who have type1 diabetes or who are pregnant should not follow this diet. Some people develop the “keto-flu,” a slang term for symptoms indicative of carbohydrate withdrawal. Numerous reliable resources are available for patients and healthcare providers.

    INTRODUCTION

     

    Did you know that the ketogenic diet was NOT initially created for weight loss? Recently, the “keto” diet has become another fad diet for people trying to lose weight. Since 2000, more researchers have started to study the ketogenic diet, causing an increase in dieters who are employing this diet.1

     

    For decades, various entities have promoted fad diets as a way to lose weight and accrue other health benefits, with no data to back them up. The ketogenic diet began to reach the public’s consciousness in the 1970s, gained popularity in the early 2010s, and by 2017, it was a frequent topic in national news media. Google searches for the ketogenic diet (sometimes called the paleo diet, which is similar but not identical) quadrupled that year; questions about this diet were in the top 10 health questions.2 Many people started using the ketogenic diet without understanding how it works or its associated benefits and risks. In 2014, celebrities like Lebron James, Kim Kardashian, and Megan Fox started using the ketogenic diet during its fad weight loss phase. In 2020, around 6% of Americans were consuming a ketogenic, high fat diet.3

     

    In the 1920s, researchers noticed that some patients with epilepsy experienced benefits during fasting, so they discovered a way to mimic fasting to treat the disease.1 Soon, physicians began to use the ketogenic diet for its antiepileptic properties.1 However, in the next decades, researchers introduced antiepileptic medications and the ketogenic diet’s popularity faded. Treatment for epilepsy still includes some of the first antiepileptic medications: phenobarbital and phenytoin.4 Although physicians began using phenobarbital in 1912 for epilepsy, the U.S. Food and Drug Administration did not approve phenytoin for use in epilepsy until 1938.5 In the 1940s, clinicians used troxidone, but its toxicity profile was unacceptable. Ethosuximide, approved in 1958, replaced it. Approval of carbamazepine and valproic acid in the 1960s made the ketogenic diet unnecessary and obsolete for the most part.5

     

    Although pharmacists are the medication experts on the clinical team, they must understand all types of treatment, including nonpharmacologic interventions. During a ketogenic diet, patients eat a limited number of carbohydrates so the body will enter ketosis. Because of the diet’s intensity, pharmacists and technicians need to understand how the diet works to ensure patient safety. When patients start or are on the ketogenic diet, pharmacists need to counsel patients to ensure no drug interactions occur. Pharmacists also need to counsel patients who may have started the diet by themselves about its benefits and the risks. Also, remember interested dieters might embrace a New Year's resolution regarding ketogenic dieting, because National Keto Day is January 5th!

     

    This continuing education activity summarizes knowledge of the ketogenic diet, the diet’s mechanism and its positive and negative effects, current medical uses for patients with epilepsy, diabetes, polycystic ovary syndrome (PCOS), and others, and recommendations for patient education and counseling.

     

    KETOGENIC DIET

     

    The ketogenic diet alters how the body burns energy, from carbohydrates to lipids. The traditional food pyramid places fats in the smallest section at the top, with carbohydrates in the largest bottom section. The ketogenic diet flips the pyramid, so most recommended foods are fats and very few are carbohydrates.

     

    According to the Dietary Guidelines for Americans, 25% to 35% of an adult’s diet should come from fats, 45% to 65% from carbohydrates, and 10% to 30% from protein.6 In a 2000 calorie day for ketogenic diet patients, fat should account for 70% to 80% or 165 g of daily caloric intake.7

     

    Although an exact timeframe is unknown, researchers believe that it can take the body up to four weeks to adapt to the ketogenic diet and ketosis.8 Patients initiating the diet could try daily exercise to force the body to break down fats, but its efficacy for reducing time to ketosis is unknown.8

     

    Ketogenesis

     

    The ketogenic diet uses ketosis and ketogenesis. When people eat carbohydrates, the body uses cellular respiration to produce energy from breaking down glucose molecules. However, if no carbohydrates are available, which would be the case during extended exercise or fasting periods, the body will naturally enter ketosis. Ketosis is a state of elevated ketone bodies, which include beta-hydroxybutyric acid, acetoacetic acid, and acetone in the blood.9 When the body needs energy, ketogenesis occurs to produce these ketone bodies, which can be used as an alternative energy source.

     

    In normal cellular respiration, acetyl-CoA is condensed with oxaloacetate to begin the citric acid cycle. Beta-oxidation of fatty acids can produce acetyl-CoA, similar to the production of acetyl-CoA from glycolysis of glucose. In times of reduced glucose (i.e., fasting, extended exercise, ketogenic diet), the body diverts the acetyl-CoA produced from the fatty acids into ketogenesis.

     

    Ketosis begins with fatty acid oxidation and the production of acetyl-CoA. Using the enzyme 3-ketothiolase, acetyl-CoA is converted into acetoacetyl-CoA. Then, the enzyme HMG-CoA synthase converts acetoacetyl-CoA to HMG-CoA.9 Low glucose levels during starvation or a high fat diet—a signal that the body needs to produce an alternative energy source for the brain—trigger this step of ketogenesis.10

     

    The last step of energy production during ketosis is the conversion of HMG-CoA to the ketone bodies acetoacetate (AcAc) and 3-beta-hydroxybutyrate (3HB). Using HMG-CoA lyase, AcAc and 3HB are cleaved from HMG-CoA.9 By being in a constant state of ketogenesis from eating fatty foods, patients on the ketogenic diet change their natural fuel source from glucose to ketone bodies.

     

    Ketone Bodies

     

    The 3 main types of ketone bodies are AcAc, 3HB, and least commonly, acetone. The liver produces AcAc, 3HB, and acetone in a 78:20:2 ratio, respectively, during fatty acid oxidation.11 Acetone is produced the least because it’s the byproduct of the uncommon and spontaneous decarboxylation of 3HB.11 Ketone bodies are the only non-glucose derived energy source for the brain.10 The brain cannot process fatty acids, so they must be converted into ketone bodies first. They provide energy to the brain because both AcAc and 3HB can diffuse across blood brain barrier.9

     

    During a normal day, ketone bodies account for only 2% to 6% of an individual's energy requirements. However, after a three- to four-day fast, ketone bodies account for 30% to 40% of the body's energy source.9 The liver can produce 185 grams of ketone bodies daily, which is enough to satisfy a person’s daily energy needs.9

     

    By using ketone bodies, patients can avoid breaking down carbohydrates as an energy source, similar to how the body naturally functions during fasting. Ketone bodies are thought to have a direct beneficial mechanism, which will be discussed later, in disorders like epilepsy.

     

    Effects of Insulin and Glucagon

     

    Insulin and glucagon are important in ketosis and ketone bodies. Low insulin levels trigger steps in the ketosis process. Insulin, also called the antiketogenic hormone, decreases 3HB production, whereas glucagon, the ketogenic hormone, increases 3HB production.12

     

    When humans consume carbohydrates and blood glucose levels rise, the pancreas releases insulin to absorb the blood sugar for energy storage.13 Insulin inhibits hormone-sensitive lipase and HMG-CoA synthase, enzymes that take part in fatty acid breakdown. It also stimulates acetyl-CoA carboxylase, causing the conversion of acetyl-CoA to malonyl-CoA, and blocking fatty acid transport into the mitochondria.10 As a result, insulin decreases the need for fatty acid oxidation and ketone bodies are decreased. The ketogenic diet requires patients to avoid carbohydrates to diminish insulin production and promote these mechanisms.

     

    Glucagon does the opposite of insulin. The body uses epinephrine and glucagon to stimulate adipose (fat) tissue to produce more fatty acid.9 Glucagon triggers phosphorylation of hormone-sensitive lipase and HMG-CoA synthase, thus promoting ketogenesis.9 The body releases fatty acids from triglycerides, so they can be broken down by the newly activated enzymes.

     

    A successful ketogenic diet requires a high glucagon/insulin ratio, similar to that experienced during fasting and by patients with diabetes. The high ratio increases fatty acid production and oxidation. Ketogenesis will follow.

     

    Foods Consumed

     

    Most foods for a ketogenic diet will have moderate amounts of proteins, no carbohydrates, with many fats. To prevent heart disease, physicians and pharmacists can counsel patients to eat healthy fats. Table 1 describes some examples of foods that are common in the ketogenic diet.

     

    Table 1. Food Options Commonly Used in the Ketogenic Diet14

    Fish and Seafood -        Full of protein

    -        No carbs

    -        Associated with positive cardiovascular and health benefits

    Poultry and Meat

    (Chicken, beef)

    -        Rich in protein

    -        No carbs

    -        Limit processed meats

    Nuts

    (Almonds, walnuts, pecans, cashews)

    -        High in fiber, protein, and unsaturated fats

    -        Very low carbs

    -        Antioxidants

    Non-starchy Vegetables

    (Broccoli, green beans, bell peppers)

    -        Include other vitamins and nutrients

    -        Antioxidants

    Cheese -        No carbohydrates

    -        High in fats, protein, calcium

    -        Too many saturated fats

    Avocados -        Potassium, unsaturated fats

    -        Most carbohydrates in avocados are fiber

     

    Patients on the ketogenic diet must understand how to track their nutrition to diet properly, calculating proteins, carbohydrates, and fats daily. Patients must calculate carbohydrates to account for dietary fiber because fiber is not digested with other carbohydrates.14 When tracking nutrition, patients on the ketogenic diet must track net carbohydrates, which can be found by subtracting the dietary fiber content from the total carbohydrates. The total carbohydrate level reported on nutrition labels does not accurately reflect the carbohydrate content the patient has consumed.

     

    Most of the foods mentioned in Table 1 are high in fat. Fish, seafood, meat, poultry, and eggs are main staples. Processed meats, like bacon, should be eaten more sparingly compared to non-processed meats, like chicken and beef.14 Patients can eat chicken and fish more frequently because they promote cardiovascular health, unlike red meat. Many people believe that berries are not allowed on the ketogenic diet, but strawberries, raspberries, and blackberries have very low net carbohydrates. The total carbohydrates in berries may appear high, but their high fiber content allows berries to have a low net carbohydrate content.

     

    A vegetarian ketogenic diet is a possibility, even though options are more limited. Vegetarian options with high protein and low carbohydrates include nuts, tofu, and seitan (a meat substitute made from the gluten in wheat).15 These dieters can also enjoy peanut butter-based desserts for more proteins. Seeds are high in fat and have high dietary fiber. For higher calorie meals, eggs and dairy (hard cheeses and plain yogurt) are an important fat option. Eggs have many fats, but essentially no carbohydrates.15

     

    Any food that is high in net carbohydrates will disrupt the body's ketosis. These are foods like starchy vegetables, juices, syrup, chips, and crackers.14 Foods high in carbohydrates will give the body enough energy to not oxidize fatty acids and prevent the production of ketone bodies.14

     

    PAUSE AND PONDER: Would a fasting patient reach ketosis quicker than a patient who is not fasting?

    WHO BENEFITS FROM THE KETOGENIC DIET?

    Obesity

    Obesity, a leading risk factor for many chronic health conditions, continues to rise in the United States. According to the CDC, the prevalence of diabetes has increased to 41.9% from 2017 to 2020.16 Many have adopted low-carbohydrate, high fat lifestyles to lose weight. A 2016 meta-analysis of 11 randomized control trials assessed the efficacy of the ketogenic diet. Among the 1369 participants, those on the ketogenic diet experienced greater weight loss than those who participated in a low-fat diet.17 After six months to two years of intervention, patients experienced significant weight loss, HDL cholesterol increase, and triacylglycerol (TAG) reduction. The studies were limited by moderate to high heterogeneity and possible publication bias. A 2021 study evaluated the efficacy of the ketogenic diet using a mobile health application in comparison to a calorie restricted, low-fat application.18 Of the 155 participants, those using the ketogenic diet app experienced greater weight loss (12.3 pounds) at 12 weeks. Hemoglobin A1c (HbA1c) and liver enzymes also improved for the ketogenic diet group. This study was limited by operating fully remotely via the application. Patients could have benefited from in-person counseling or on-site visits to promote adherence.18

    Another meta-analysis of 13 randomized controlled trials showed that participants on the ketogenic diet benefited from greater weight loss than those on a low-fat diet proving that the ketogenic diet can be used for obese patients. The low-fat diet group consisted of 787 patients while the ketogenic diet group consisted of 790. Patients that were part of the keto group lost approximately 3.6 pounds (1.6 kilograms) more than the low-fat group.19 Patients saw a greater increase in HDL and a more significant reduction in TAG in the keto group.

    Type 2 Diabetes

    Patients with type 2 diabetes (T2D) sometimes benefit from the ketogenic diet through improved glycemia and reduced insulin resistance. A study of 28 patients with T2D following a ketogenic diet showed that blood glucose and HbA1c improved. The ketogenic diet could potentially help patients with T2D reduce the number or dose of medications.20 Another comparative study showed that obese patients with T2D had improvement in blood glucose profiles, insulin sensitivity, and HbA1c when adhering to the ketogenic diet for two consecutive weeks.21 However, the study was limited by short duration and small sample size.

    Polycystic Ovary Syndrome

    Similar benefits seem to apply to patients with polycystic ovarian syndrome (PCOS). Patients with PCOS experience hyperandrogenism, insulin resistance, and ovulatory dysfunction.22 Current treatment options include metformin, clomiphene, and letrozole; the ketogenic diet may provide good results for these women through insulin reduction.

    In addition to the symptoms listed above, women with PCOS tend to gain weight, develop acne, and experience hirsutism.23 Physicians recommend lifestyle modifications and hormonal contraceptives as first line interventions, but often, these interventions are insufficient, and symptoms persist.23

    Researchers have conducted many studies to evaluate the benefits of the ketogenic diet for women with PCOS, yet the studies are greatly limited by sample size. For example, a 2019 study consisting of 14 women with PCOS struggling with their weight assessed changes in body weight, BMI, fat body mass, lean body mass, HDL, and several other parameters. At 12 weeks, participants saw a 9.43-kilogram (20.7 pound) reduction in body weight, 3.35 reduction in BMI, and an 8.29-kilogram (18.2 pound) reduction in fat body mass.23

    A pilot study consisting of five women tested the ability of the ketogenic diet to reduce PCOS symptoms. Researchers provided the women with low-carbohydrate diet books and handouts alongside group meetings to test the ketogenic diet’s efficacy for PCOS. Participants consumed fewer than 20 grams of carbohydrates per day for six months. To test participants’ adherence, researchers measured ketones and body weight. Throughout the 24-week period, participants lost weight with a mean BMI decrease of four kilograms (approximately 8.8 pounds) which was a 14.3% total reduction in body weight.24 The study resulted with clear reductions in testosterone, fasting serum insulin, and an overall improvement of PCOS symptoms.

    Additionally, an eight-week crossover study involving 30 women with PCOS demonstrated various benefits. On average, weight loss ranged from 1.3 to 1.6 kg (2.8-3.5 pounds). When compared to baseline, the results of this study highlight the relationship between decreases in testosterone and fasting insulin.25 Overall, improvements in insulin resistance, testosterone levels, and weight loss, the ketogenic diet may help patients with PCOS.

    Epilepsy

    The original use for the ketogenic diet was as an antiepileptic therapy in children.1 After the discovery of antiepileptic medications, the need for the ketogenic diet diminished. However, researchers are bringing the ketogenic diet back to help treat patients who are refractory to modern antiepileptic medications.

    In combination with medications, researchers have seen up to a 50% reduction in the number of seizures patients are having, with 10% to 15% becoming seizure free.26 Co-administration with antiepileptics is possible for some medications. However, most patients are children and maintaining this strict diet is difficult.

    During a retrospective study, researchers compared the effects of the ketogenic diet to modern anticonvulsant medications in 150 children. At one year, 55% of patients remained on the diet, and 27% of the patients who remained in the trial had a greater than 90% decrease in seizure frequency.27 The diet allowed children to reduce their medication burden (patients averaged having 6.2 anticonvulsant medications before the trial), and proved to be more effective than many medications. More studies in larger patient populations are needed over longer periods of time to make stronger conclusions.

    Research attributes the ketogenic diet’s anticonvulsant properties to an increased seizure threshold. Mitochondria in the brain have healthier biogenesis and density, leading to increased resistance to metabolic stress.28 Another way the diet increases seizure threshold is through decreased glucose consumption and production of glycolytic ATP.28 Subsequently, potassium channels remain open and hyperpolarize the neuronal membrane.28

    Researchers have found that ketone bodies produced from fatty acid oxidation have their own anticonvulsant effects. Although different ketone bodies have different effects, researchers have found that they can alter various neuronal membrane transporters to decrease excitability. Ketone bodies can inhibit transporters like the vesicular glutamate transporter and neuronal potassium channels. Inhibition of these transporters prevents signal transmission and causes decreased excitability of neuronal cells.29

    Other Neurodegenerative Disorders

    In addition to epilepsy, promising evidence shows that the ketogenic diet has favorable effects for other neurodegenerative disorders. As the incidence of Alzheimer’s disease (AD) increases, few treatment options are available. The ketogenic diet may reduce deposition of amyloid beta (Aβ) plaques in patients with AD. With the addition of D-β-hydroxybutyrate (an enantiomer of the ketone body 3HB) to the ketogenic diet, ketones were able to increase neuron survival by reversing Aβ (1-42) toxicity. 30 By increasing ketone production in the liver, the ketogenic diet can reduce the production of reactive oxygen species.31 Ketone bodies also work to block histone hyper-acetylation initiated by histone deacetylases (HDACs), increasing antioxidant levels. The ketogenic diet can improve metabolic efficiency which improves ATP concentrations resulting in further protective effects.31

    Ketones’ neuroprotective effects can potentially help patients with Parkinson’s disease by reducing oxidative stress, maintaining energy supply, and modulating deacetylation and inflammatory responses.31,32 Because they can reduce inflammation and inhibit the glutamate excitatory synapse, infusions of ketone bodies like 3HB may lead to small improvements in Parkinson’s symptoms.32 The use of the ketogenic diet for Parkinson’s is still controversial, thus further research is necessary.

    Glaucoma

    Glaucoma is the second leading cause of vision loss in the world.33 Because ketone bodies are the major source of energy when participating in the ketogenic diet, mitochondrial dysfunction in the retina and optic nerves associated with glaucoma may be decreased.32,34 A 2020 observational study assessed the benefit of the ketogenic diet in 185,638 adults with glaucoma from three studies between 1976 and 2017. Results showed that following a low carbohydrate diet was associated with 20% lower risk of developing primary open-angle glaucoma with initial paracentral visual field loss.35 However, evidence is still lacking, and researchers need to investigate more to prove the ketogenic diet’s efficacy for glaucoma.

    Colorectal Cancer

    According to the American Cancer Society, colorectal cancer is the third leading cause of cancer-related deaths in men and women in the United States.36 A 2022 study suggests that the ketone body, 3HB, can suppress colorectal cancer.37 In one experiment, investigators evaluated the ability of the ketogenic diet to prevent tumor growth and development in mice.

    They discovered that 3HB could suppress tumor growth by reducing proliferation of colonic crypt cells.37 3HB induced positive changes in tumor growth through the upregulation of the homeodomain-only protein X (HOPX). The HOPX protein inhibits cancer organoid growth when overexpressed.37 Mice fed the ketogenic diet showed elevated levels of HOPX specific to the colonic tissue.

    Overall, mice assigned to the ketogenic diet experienced improved long-term survival rates. To test the efficacy of the ketogenic diet for existing tumors, after two cycles of dextran sodium sulfate, researchers introduced the diet to the mice. After exposure to the diet, tumor growth decreased. When researchers discontinued the ketogenic diet from the mice, tumor development proceeded.37

    This discovery led to further testing, this time in human organoids. Organoids are tissue cultures derived from stem cells.38 In the right environment, they are used to replicate organs. They are an essential tool to monitor disease development. Findings mimicked the results from the mice in 41 patients with colorectal cancer. This suggests that the ketogenic diet may be used for the prevention and treatment of colorectal cancer in the future.37

    PAUSE AND PONDER: How do you think patients would feel using the ketogenic diet as a primary treatment for neurodegenerative diseases in the future?

    Contraindications to the Ketogenic Diet

    Some patients should not follow the ketogenic diet. It is contraindicated in patients with liver failure, pancreatitis, inborn disorders of fat metabolism, primary carnitine deficiency, carnitine palmitoyl transferase deficiency, carnitine translocase deficiency, porphyria, and pyruvate kinase deficiency.39,40

    Because of the high risk of developing diabetic ketoacidosis (DKA), patients with type 1 diabetes on SGLT2 inhibitors should not participate in the ketogenic diet.41 DKA occurs when the body produces a dangerously high level of ketones at a rapid pace. Feeling extremely thirsty and frequent urination are early symptoms of DKA. Later symptoms of DKA include dry skin and mouth, flushing, fatigue, stomach upset, and pain. Another notable warning sign of DKA is a fruity odor on the patient’s breath. Acetone is responsible for the sweet scent and indicates high levels of ketones in the body.42 If left untreated, DKA can further develop, ultimately leading to death.

    Pregnancy is also a contraindication. The CDC recommends 340 additional calories per day during the second trimester of pregnancy and 450 additional calories per day during the third trimester.43 The CDC also recommends a well-balanced diet for women who are expecting. Losing weight during pregnancy is not safe and can be harmful to a patient’s baby.43 Folic acid and iron supplementation is pivotal in a fetus’ development. The World Health Organization recommends daily iron and folic acid supplements to reduce the risk of low birth weight.44 If a pregnant woman were to go on the ketogenic diet, she would need to ensure she consumes the suggested dose of 120 mg elemental iron and 2800 µg (2.8 mg) folic acid daily.44 Overall, no evidence indicates that the ketogenic diet is safe for pregnant women.

    KETOGENIC DIET SAFETY AND COUNSELING

    Although several studies suggest the ketogenic diet can be effective for weight loss, limited literature is available concerning its long-term effects. Long-term effects include hepatic steatosis, hypoproteinemia, kidney stones, and vitamin and mineral deficiencies.40

    Currently, no guidelines address the ketogenic diet specifically, and other guidelines do not include the ketogenic diet for the treatment of the previously mentioned diseases. Researchers must complete longer term studies with larger patient populations to prove the ketogenic diet’s benefits and elucidate any long-term risks. Pharmacists and other healthcare providers should keep this in mind when recommending the diet to patients.

    The Keto-Flu

    A common adverse effect of the ketogenic diet is the “keto-flu.” The symptoms are indicative of carbohydrate withdrawal that can create symptoms like brain fog, fatigue, nausea, vomiting, constipation, and muscle soreness.40, 39 Symptoms usually begin within one to two days and resolve within a week or less. Pharmacists can counsel patients on proper hydration, light exercise, rest, and starting the diet slowly to try to prevent the keto-flu.

    Cardiovascular Effects

    As research has previously shown, the ketogenic diet shows short-term benefits for obesity and cholesterol. Due to the overconsumption of fats, researchers wondered about the longer-term effects. In rodent studies, the ketogenic diet led to the development of hepatic inflammation and nonalcoholic fatty liver disease.45 Limited research has been done for nonalcoholic fatty liver disease in humans and more study is needed.

    Other Adverse Effects

    While on the ketogenic diet, patients may experience constipation. The healthcare team should implement a bowel regimen for the patient including an agent like polyethylene glycol 3350 (MiraLAX®) that’s sugar-free, meaning it adds no additional carbs. Other notable side effects are kidney stones and a decrease in bone density. To prevent kidney stone occurrence, pharmacists can counsel patients on drinking large amounts of liquids.. Patients can reach out to their providers to ensure they check bone health routinely. Several advisory groups recommend bone mineral density screening for women aged 65 and older and men aged 70 and older, and for other patients who are at high risk. Patients participating in the ketogenic diet are no exception, and could be considered high-risk if they do not consume enough calcium and vitamin D. Pharmacists can counsel patients to monitor their calcium and vitamin D intake and supplement it if necessary. Upon screening, providers may also recommend calcium and vitamin D supplementation for patients who experience a decline in bone mineral density.46

    What Can Health Professionals Do?

    Pharmacists can counsel patients on ketone testing to prevent occurrences of DKA. When a patient’s blood glucose exceeds 240 mg/dL, testing ketone levels every four to six hours is warranted.47 Ketones can be monitored through the urine and blood. A urine stick test is the most common and changes color depending on the ketone level. Although urine tests are convenient, blood ketone tests from finger sticks are more accurate because they measure 3HB and/or AcAc in the blood.48 If ketone tests indicate high levels, the patient is at moderate or high risk for ketoacidosis and patients should seek medical attention. Table 2 shows normal ketone levels, the optimal state of nutritional ketosis, and the level for ketoacidosis.

    Table 2. Ketone Levels48
    Normal Ketone ≤ 0.5 mmol/L
    Nutritional Ketosis 1 - 3 mmol/L
    Ketoacidosis ≥ 20 mmol/L

    Patient adherence to long-term regimens always becomes challenging. Counseling patients on the importance of sticking to their diet and other medications will increase the likelihood of desired results.

    PAUSE AND PONDER: On average, how long do you think a patient can remain adherent to the ketogenic diet lifestyle?

    Medication management is a vital component of patient safety. To ensure that starting the ketogenic diet is safe, a healthcare professional should perform a complete medication reconciliation. Pharmacists, with an interdisciplinary team, should then develop a plan for medication adjustments (including OTCs) and carbohydrate intake. The use of medication package inserts, institutional databases, and manufacturer helplines can assist the team in determining carbohydrate content of drugs to make the process more seamless.46 The following oral suspensions contain high carbohydrate contents:49    

    • Amoxicillin
    • Nystatin
    • Levetiracetam
    • Midazolam
    • Phenobarbital
    • Phenytoin
    • Baclofen
    • Ibuprofen

    Making patients aware that they must inform the healthcare team of any new medications is equally as important.

    Some medications are of concern with the ketogenic diet.

    • Patients taking SGLT2 inhibitors should not participate in nutritional ketosis due to the increased risk of diabetic ketoacidosis.
    • Clinicians need to monitor patients taking the anticonvulsant valproate (a fatty acid) and might need to adjust their doses since the ketogenic diet increases metabolic efficiency and valproate can be burned by cells for energy.50 Patients may feel as though valproate is not as effective after starting the ketogenic The dose, in this case, may need to be increased temporarily.
    • A case study showed that topiramate can increase blood pH, inducing metabolic acidosis and kidney stones.51 This may become hazardous if patients are already in nutritional ketosis.
    • Patients may experience hypotension while taking antihypertensive agents and following the ketogenic They should monitor blood pressure frequently.

    Pharmacists and other health professionals should inform patients to stay hydrated to reduce the risk for kidney stones and eat low salt food items.

    MYTHS AND FACTS

    The ketogenic diet has become increasingly popular over the years. Halle Berry, Vanessa Hudgens, Kourtney and Kim Kardashian are a few of many celebrities that have tried the ketogenic diet and have seen incredible results. MTV’s Jersey Shore star, Vinny Guadagnino, also known as the Keto Guido, is no stranger to the diet and has even written a keto cookbook. Seeing such drastic transformations all over tabloids and social media, without a doubt leaves people wondering “Why not? If they can do it, so can I,” while others think, “This can’t be real.”

     

    Many misconceptions create skepticism among patients from the abundance of information available on the internet. Pharmacists can alleviate patient worries by staying informed and referring patients to reliable resources. Table 3 below dispels common myths.

     

    Table 3. Myths and Facts About the Ketogenic Diet52
    MYTH FACT
    The ketogenic diet is bad for your health. The ketogenic diet has several health benefits including:

    ●      Weight loss

    ●      Improved brain function

    ●      Reduction of seizures

    ●      Blood sugar management

    ●      Improvement of PCOS symptoms

    Side effects may include nausea, vomiting, constipation, or other common side effects.

    All I have to do is consume any type of fat while going keto. Patients should eat healthy fats like avocados, nuts, seeds, and fish. Healthy fats lower LDL levels and raise HDL levels. Unhealthy fats saturated and trans fatty acids (e.g., fried foods, pastries, butter, and cream) raise LDL levels.
    If I go keto, I will get ketoacidosis. Ketosis and ketoacidosis are different conditions. The ketogenic diet induces ketosis.

    ●      In ketosis, the body burns fat since carbohydrates are unavailable. Nutritional ketosis is a normal response.

    ●      Ketoacidosis is a complication seen primarily in patients with T2D where the blood becomes acidic. It can be life-threatening.

    I will have no energy if I start a ketogenic diet. Some people may experience an adjustment period while beginning the ketogenic diet. They may experience temporary fatigue, brain fog, or the “keto-flu.” Eventual ketone production fuels the brain with energy and resolves symptoms.
    The ketogenic diet is only useful for weight management. The ketogenic diet has proven effective in patients with diabetes, PCOS, metabolic syndromes, Alzheimer’s disease, and obesity.
    I can’t drink any alcohol while on the ketogenic diet. Various low-carb alcoholic beverages can be substituted. Light beer, vodka, gin, and rum are a few examples, but patients should keep intake low-moderate. Patients should avoid sweet drinks and cocktails to prevent high sugar intake.

     

    Another common misinterpretation is that any low-carbohydrate food is considered keto. No food item has the same benefit as the other. The healthcare team must work with patients to create dietary plans that are more feasible for them. With a tailored diet plan, patients are more likely to feel structured and reach their goals. Overall, providers should conclude that patient education is necessary to certify patient trust and safety.

    CONCLUSION

    Following a low-carbohydrate, high fat diet that uses ketone production to fuel the body requires a large selection of foods if patients are to maintain this diet. This is the challenge of the ketogenic diet. Pharmacists and technicians need a good understanding of what this diet is—and what it is not—so they know when prescribers are likely to use it for diseases. Pharmacists, as they screen for contraindications, should identify the signs of ketosis and counsel patients on managing safe ketone levels.

    Patient education is the key to reaching patient goals. Pharmacists must be ready to address patient questions and concerns regarding the ketogenic diet in conjunction with current medications. When pharmacists are a part of the care process, outcomes improve.

      ABSTRACT

      Compounding of drug preparations requires training and knowledge in the science underlying pharmaceutical compounding. Altering the original drug product can change the drug’s stability and clinical efficacy. The United States Pharmacopeia (USP) is an independent non-profit organization of knowledgeable volunteers who set the standards for pharmaceutical compounding to ensure patient safety. State regulating bodies oversee and enforce these standards at compounding pharmacies to ensure compounded preparations are up to quality and purity standards. Since the field of pharmaceutical compounding is constantly changing, USP revises its standards regularly. The USP recently revised General Chapter <795> Pharmaceutical Compounding – Nonsterile Preparations with revisions enforceable on November 1, 2023. To make this transition easier, this continuing education activity outlines the most significant changes made to USP <795>. USP changed General Chapter <795> Pharmaceutical Compounding - Nonsterile preparations to mimic those of USP General Chapter <797> Pharmaceutical Compounding – Sterile Preparations. Overall, the revision elevates nonsterile compounding’s quality and sanitary standards to improve patient safety by reducing common safety errors seen across the United States.

      CONTENT

      Content

      Introduction

      The original “little blue pill” was created in the 1860s and was a popular cure for everything from toothache to tuberculosis.1 Pharmacists compounded “blue mass syrup” and “blue pills” based on their own recipes or on one of several widespread recipes. Its name probably derives from the use of blue dye or blue chalk (used as a buffer) in some formulations. Blue mass’s ingredients varied, as each pharmacist prepared it himself, but they all included elemental mercury. One recipe for blue mass syrup consisted of1

      • 33% mercury (measured by weight)
      • 5% licorice
      • 25% Althaea (a root extract, possibly from hollyhock or marshmallow)
      • 3% glycerol
      • 34% rose honey

       

      Pharmacist-compounders produced blue pills by substituting milk sugar or chalk for the glycerol and rose oil for the rose honey. Each pill contained one grain (64.8 milligrams) of mercury and was prescribed two to three times a day, which today we know causes heavy metal poisoning, since the dose is more than 100 times more than the limit set by the Environmental Protection Agency.1 Products were made without fancy definitions or regard to cleanliness. Times have changed.

       

      Pharmaceutical compounding is the act of manipulating a drug product to create a new drug formulation.2 Pharmacists and pharmacy technicians still compound drug preparations for a specific patient or group of patients when no drug product exists on the market, or as seen more recently, when the drug product is backordered with no therapeutic alternative(s). It is also interesting to note what the United States Pharmacopeia (USP; described below) does NOT consider to be compounding. Preparing a powdered antibiotic bottle with distilled water per manufacturer’s directions is not considered compounding. Splitting tablets and repackaging is also not considered compounding, nor is preparing a single dose for a single patient to be used within four hours. In other words, making one dose of blue mass syrup and giving it directly to a patient is not compounding. (OK, maybe no one makes blue mass syrup anymore, but crushing a tablet and placing it in a liquid for immediate use is still not a compounded preparation.)

       

      Pharmaceutical compounding has two categories: sterile compounding and nonsterile compounding.2

      • Sterile compounding is creating a new drug preparation that must be sterile (completely free of pathologic microorganisms) and includes preparations that are primarily infusions, injections, eye drops, and many irrigations.
      • Nonsterile compounding is creating a new drug product that is not required to be sterile (although these products should be as “clean” as possible) and are mostly used for oral or topical administration. Nonsterile compounding is often employed for pediatric and veterinary preparations where patients need very small or very large doses. Some examples are medicated creams for neuropathic pain, and anesthetic mouthwashes for oral sores and pains.

       

      The USP is an independent non-profit organization of knowledgeable volunteers who set the standards for pharmaceutical compounding to ensure patient safety.3 The USP also distinguishes guidelines for hazardous and non-hazardous compounding. Both sterile and nonsterile compounding can involve manipulation of hazardous drugs. This continuing education activity focuses on non-hazardous nonsterile compounding. More information on hazardous compounding can be found in General Chapter <800> Hazardous Drugs – Handling in Healthcare Settings. Access to the USP Compounding Compendium costs $250.00 for a 12-month membership. There are also various plans for multiple users. Many institutions have a contract with USP. (Readers should check with their designated person or supervisor, as they may already have access to this service.)

       

      The origin of nonsterile pharmaceutical compounding in the U.S. cannot be pinned down to one exact date, but historically, the 1800s saw immense growth in not only population but also in disease states as people traveled and settled to new areas. Between 1840 and 1850, it is estimated that more than 1.5 million persons immigrated to the United States. Backyard herbalists became highly regarded apothecaries seemingly overnight.4

       

      Unfortunately, there were no established compounding standards until 1820 when a small group of physicians raised concerns about the high prevalence of poor-quality medicine across America and the USP was formed. By 1863, during the height of the Civil War, the USP had become the most trusted source for information about medicines.3.

       

      The USP continuously strives to improve the quality of drugs, including compounded preparations. Today we know that the quality of a compounded preparation depends as much on handwashing, gloving and cleaning, as checking the pH of the product itself. These steps are necessary to safeguard the preparation that a pharmacist or pharmacy technician compounds, and ultimately, safeguard the patient.

       

      The USP sets standards for pharmaceutical compounding but has no regulatory authority, so it does not enforce the standards it sets. Each state is responsible for regulating pharmaceutical compounding, but the Food and Drug Administration (FDA) is also authorized to regulate all aspects of drugs, including compounding. Both state regulating bodies and the FDA can inspect compounding in pharmacies and take legal action and can amass fines if compounders do not uphold USP standards. However, this action only applies to states that write USP standards into their laws. Depending on the situation’s severity, legal action could result in a loss of license for the pharmacy or pharmacist.

       

      The USP sets standards for sterile and nonsterile compounding through General Chapter <797> and General Chapter <795>, respectively. (Here’s a PRO TIP: chapters numbered from 1 to 1000 are enforceable by state and federal agencies). More recently, the FDA has been inspecting compounding pharmacies to ensure they meet General Chapter <797> standards, but it is only a matter of time before these agencies turn their attention to General Chapter <795>.

       

      In November 2022, the USP published a revised General Chapter <795> Pharmaceutical Compounding – Nonsterile Preparations. Going forward, we will call these standards the newly revised standards. This revision now includes a designated person (the individual assigned to be accountable and responsible for the compounding facility’s operation, performance, and personnel) requirement to mimic General Chapter <797>. With the implementation of a designated person for nonsterile compounding under proposed General Chapter <795>, when the facility is not up to code, State boards of Pharmacy and the FDA hold the designated person responsible, creating a risk of loss of license. The revised standards will be official in November 2023. Major changes include

      • garbing
      • cleaning
      • training
      • beyond-use dating and
      • a designated person requirement

       

      The focus here is on how to implement the major changes made to the currently enforceable General Chapter <795>, which was revised and reissued in 2020. Going forward, we will call these standards the current standards. Once readers are familiar with this summary of the major changes in the newly revised standards, they are encouraged to review the full text of the proposed chapter <795> to address additional minor changes.

       

      So, to repeat, the standards that were revised and reissued in 2020 and are currently enforceable will be called the current standards. The revision that will be adopted in November 2023 will be called the newly revised standards.

       

      Garbing

      The newly revised standards put greater emphasis on garbing procedures for nonsterile compounding than the current standards do. Pharmacy personnel who compound sterile preparations are well acquainted with garbing, however, garbing is a foreign concept to many who prepare nonsterile preparations. Think back to the past. How often did you go to the back of the store, push some items on the counter aside, and start mixing a magic mouthwash? You probably made it wearing a shirt and tie or more formal dress, while possibly wearing a lab coat, unless it was a really hot day. You might even have washed your hands if you just came back from lunch. Conversely, many hospital pharmacies mix magic mouthwash in so much garb, that you might think that it is a toxic preparation. The SIDEBAR explores this topic in greater detail.

       

       

      TECH TALK SIDE BAR5

      Have you noticed that many pharmacists and pharmacy technicians no longer wear white lab coats? Physicians began to wear white coats in the late 1800s as doctors started to recognize the color white’s effectiveness. It is easier to see dirt and soil that prompts the wearer to launder it, and frequent laundering helps reduce pathogens. Soon all medical professionals adopted the practice. White coats were worn not only to protect one’s clothing, but they were seen as a sign of prestige and respect.

       

      Today, white coats are rarely used, because according to Dennis Miller, “White coats cause white coat syndrome” (hypertension) and they “increase the distance between the pharmacist and the customer.” Few states regulate pharmacy technician attire. Many institutions and most large retail chains require pharmacy technicians to wear uniform “scrubs.” Restricting white coats to professional staff may reduce some customer confusion, but in certain situations, scrubs might imply the wearer is a nurse or other hospital professional, which is also confusing. One of this CE’s authors says, “I can’t even tell you how many patients and families would ask if I was a nurse.”

       

      Recently, some hospitals have banned pharmacy technicians from wearing scrubs, forcing them to wear civilian clothing. Unfortunately, that makes technicians look like pharmacists again. Of course, some pharmacists like to wear scrubs to work; are they secretly wishing they were technicians? Doubtful. Business attire has certainly gone downhill lately. So, if we can’t wear a white coat and we can’t wear scrubs, what are we to wear?

       

      THE ANSWER (which is required by law in many states): A name tag that indicates your position!

       

       

      The current standards state that personnel involved in compounding should garb “as needed for personal protection and to prevent contamination” of the compounded nonsterile product (CNSP) prior to preparation.6 For example, compounding staff don two pairs of gloves for personal protection when preparing cytotoxic CNSPs for their own safety. More information on hazardous compounding can be found in General Chapter <800> Hazardous Drugs – Handling in Healthcare Settings. The current standards also state compounding personnel are responsible for maintaining good hand hygiene and wearing appropriate clothing to prevent contamination of the CNSP.6 These statements give compounding personnel some latitude when they make decisions. For example, currently, some compounders don gloves to make magic mouthwash, while many others prepare it with ungloved hands in their practice. Nonsterile gloves will become mandatory on November first.

       

      The newly revised standards now specify hand washing and garbing procedures and provide guidance on personnel who should NOT prepare a CNSP. Compounding personnel are to remove all “garments that cannot be easily cleaned” before entering the designated compounding area. So compounding personnel must now remove personal outer garments (such as jackets, sweaters, hats, and scarves), hand and wrist jewelry, anything that might hinder the use of gloves, and headphones must be removed before compounding something as simple as magic mouthwash. Compounding personnel must wash their hands for at least 30 seconds and dry with one-time use paper towels before compounding as well. After handwashing, personnel must don nonsterile gloves and inspect the gloves for holes, rips, or tears. Compounding personnel should wipe or replace gloves in between different preparations and must remove these gloves before leaving the designated compounding area.6 These proposed standards are analogous to the procedures required for sterile compounding. In fact, the format of and definitions within the revised <795> aligns with the revised <797> for sterile products much more closely than in the past.

       

      The current standards still require personnel to be in good health and fit for compounding, but the revisions are considerably more specific. Personnel who have new tattoos, oozing sores, open wounds, conjunctivitis, rashes, or active respiratory infections are not considered fit to compound due to risk of contamination of the CNSP. The newly revised standards hold the designated person responsible for deciding if personnel are fit for compounding or not.6

       

      Cleaning the Designated Compounding Area

      Do I need to create an area for compounding? Yes. The newly revised standards describe a designated compounding area in detail. Some readers are thinking, “My pharmacy is small. Can I use the area for tasks other than compounding?” The designated compounding area is a space with a marked perimeter that is required to be clean, orderly, sanitary, well-lit, and have low foot traffic, and no other activities can occur in this space simultaneously. You may perform other duties there if there is no compounding going on as long as someone cleans the area before compounding again. The newly revised standards suggest the designated compounding area be uncarpeted for easier cleaning, which in one of this CE’s author’s opinion should be changed to a must, since carpets tend to harbor dust and dander, and can be very difficult to clean. (Have you ever dropped and broken a bottle on the carpet in your pharmacy? It’s not pretty.)

       

      The compounding area must be used in a manner that prevents cross contamination of CNSPs from other areas of the pharmacy. For compounding to be completed in the most efficient manner possible, all equipment in the designated compounding area must be arranged in a way that prevents errors. Last, the facility’s standard operating procedures (SOPs) must always include this information and be available to staff.

       

      The current standards simply state that compounding equipment “shall be clean, properly maintained and used appropriately.”6 This statement allowed compounding personnel to decide on their own standard of clean when preparing a CNSP and their own definition of when or if they should clean. The newly revised guidelines strengthen the minimum requirements for cleaning the designated CNSP compounding area. The USP dedicates an entire section to cleaning procedures, representing a major change in the standards. The new standards indicate that personnel must clean the perimeters—walls and ceilings—when visibly soiled, after spills, and when surface contamination occurs.6 Readers will see that visible soil, spills, and surface contamination form a frequent theme in the newly revised standards!

       

      The new standards also establish a routine cleaning schedule. The section, “Cleaning and Sanitizing” states pharmacy personnel must clean work surfaces at the beginning and end of each shift at a minimum, between each CNSP, and again if spills or surface contamination occurs. The standards add that personnel must clean floors daily on days when compounding occurs, and again if spills or surface contamination occurs.6. Personnel must clean storage shelves every three months, after spills, and when surface contamination occurs. Personnel qualified to clean can be defined as any staff member who has been properly trained and observed in a facilities cleaning procedures. That means that pharmacy staff can train housekeeping staff to complete the cleaning.

       

      Personnel need to clean and sanitize, and if two separate products are used—one to clean and one to sanitize—cleaning is done first, followed by sanitizing second. Selecting appropriate cleaning products requires careful attention. They should be (1) compatible, (2) effective, and (3) leave minimal residue. Finally, daily documentation is essential on days when compounding occurs.6 An old adage applies here: cleaning is not truly done unless it is documented. High tech organizations commonly complete this documentation using an online platform integrated with other daily documentation requirements such as daily temperature monitoring, but a simple sign off sheet is also acceptable. A best practice is to include any cleaning and its documentation into the compounder’s daily workflow, so it is not forgotten. Daily and or weekly task charts can be created to include all activities that need to be performed.

       

      PAUSE AND PONDER: How were you originally trained to compound? Were you told to watch how it was done and then you were on your own?

       

      Training

      Another major area of change is the training of compounding personnel. The current standards state that compounders must be “proficient in compounding” and suggest that compounders should pursue knowledge by attending seminars or studying literature related to compounding. It also states that compounders must be conversant on General Chapter <795> and familiar with General Chapter <797>. With standards this vague, and no required number of CE credits on this subject, how often do you think compounding personnel previously searched for compounding topics? Also, the current standards simply require at a minimum compounding personnel to be trained and capable of the compounding duties assigned to them, and for someone to document the training. Compounding duties include verifying critical processes like weighing and mixing that occur frequently during compounding.

       

      The newly revised standards will require a more structured training program for compounding personnel. All compounding personnel must complete this training program initially before being allowed to compound and every 12 months thereafter. The newly revised standards require compounding personnel to repeat compounding procedures “independently while under the supervision of the designated person or assigned trainer for completion of the training program.”6 The organization’s designated person will be responsible for designing the training program, which must include

      • the required training, meaning a detailed description of the training
      • the frequency of training, and
      • the process used to evaluate competency.

       

      Table 1 lists the training program’s required topics. It is interesting to note that pharmacists who do not compound but complete in-process checks, verification, or dispensing also must complete the CNSP training program before completing checks, verification, or dispensing. A training program may include an online portion of reading or videos teaching concepts with quizzes to evaluate understanding, and a physical portion to evaluate measuring, mixing, and overall compounding. The designated person or assigned trainers can train personnel, and of course, they must document the completion of the training program.6

       

      Table 1. Proposed General Chapter <795> Required Topics for Training6

      Training programs must teach compounding personnel the following:
      ·       cleaning and sanitizing
      ·       documentation such as Master Formulation Records and Compounding Records
      ·       hand hygiene and garbing
      ·       handling and transporting CNSPs and their components
      ·       measuring and mixing
      ·       proper use of compounding equipment and devices
      ·       understanding General Chapter <795>
      ·       understanding safety data sheets
      ·       understanding procedures to complete compounding duties

       

      It is important to note this table only lists the minimum requirements, additional requirements may be necessary according to each facility’s needs.

       

      The Designated Person

      The necessity to designate a person who has oversight and full responsibility for compounding practices now in General Chapter <800> is included in proposed General Chapter <795> and <797>. The current standards again broadly describe the requirements. The chapter states that compounding personnel are responsible for adhering to the general principles of compounding outlined in the current standards. It specifies several responsibilities, which include training, selecting ingredients for compounding, labeling, and cleaning. However, since the compounding process may include many people, the ultimate accountability is unclear.

       

      To clarify accountability, the proposed General Chapter <795> requires each organization to designate one or more persons to be responsible and accountable for nonsterile compounding. The designated person’s responsibilities include ensuring the organization develops written formal quality control and quality assurance procedures and reviews them annually. The designated person must monitor and observe compounding, identify areas of error, and take corrective action if needed. The designated person has several other responsibilities. These include6

       

      • establishing, documenting, and monitoring SOPs within the CNSP compounding area to include component handling and storage
      • ensuring that all staff members follow all SOPs
      • reviewing complaints
      • determining if potential issues are likely with CNSPs
      • selecting components to be used in compounding

       

      Beyond Use Dates

      The final major difference is the establishment of beyond-use dates (BUD) for CNSPs. The current standards hold compounders responsible for establishing BUDs based on their observation of the drug during compounding. Compounders (not a designated person) are held responsible for noticing signs of instability and using their education and experience to assign a BUD to the final preparation.6 The current standards also recommend assigning BUDs based on three categories: non-aqueous, water-containing oral, or water-containing topical. The new guidelines are based on the activity of water (aw) in each product.

       

      Table 2 compares the current and proposed BUD recommendations.6

       

       

      Table 2. A Comparison of BUD Requirements6,7       

      Description Minimum BUD requirement

      Aqueous preserved 14 days in refrigerator 35 days controlled room temp or refrigerator
      Aqueous topical

      (Cream, lotion, shampoo, nasal spray, gel, rinse, foam, etc.)

      30 days 35 days if preserved

      14 days if non-preserved

      See activity of water chart

      Nonaqueous oral

      (Oil or powder filled capsule, glycol or oil based oral solution, compressed tablet, powder for inhalation, troche, lollipop, etc.)

      6 months 90 days
      Nonaqueous

      (Medicated stick, ointment, suppository, etc.)

      6 months 180 days (6 months)

       

      Proposed General Chapter <795> determines BUDs based on a preparation’s water activity (aw, see SIDEBAR), which is more clearly defined as aqueous and non-aqueous by the following distinction:

       

      • CNSPs with an aw ≥0.6, considered aqueous dosage forms
      • CNSPs with an aw <0.6, considered non-aqueous dosage forms

       

       

      SIDEBAR: Activity of Water7-10

      The water in a preparation can “participate in chemical, biochemical, or physicochemical reactions.” However, it is not the water content (such as % water in the CNSP), but rather the activity of water that determines the water’s availability to participate in degradation reactions and allow microbial growth. Therefore, compounders must determine a BUD by considering the preparation’s water activity and not the preparation’s water content.

       

      Water activity is roughly equivalent to relative humidity, except that relative humidity is expressed in terms of percent and water activity is expressed as a fraction. So, a water activity of 0.6 is roughly equivalent to 60% relative humidity. If the dosage form with a water activity of 0.6 were to be sealed in a package, any surrounding space would eventually have a relative humidity of 60%. Compounders can measure water activity for a specific preparation by the procedures outlined in General Chapter <922> Water Activity. However, the proposed General Chapter <795> provides an easy classification system (see Table 3).

       

      The aw cut-off of 0.6 established in USP comes from various studies showing no microbial growth of any kind in foods below this value. Although the water activity determination was constructed using food, it is also the basis of USP <1112> Water Activity Determination and is the foundation for the BUD rationale in the proposed <795>. A product with an aw greater than or equal to 0.6 has been shown to have increased bacterial, fungal, and other microbial growth. However, in products with an aw below the threshold of 0.6, no microbial growth was found.

       

       

      The newly revised standards recommend adding antimicrobial agents to any CNSP with an aw at or exceeding 0.6 when assigning a BUD of 35 days. Even components as simple as ascorbic acid can help extend the BUD. As always, careful research must be done to determine suitable preservatives for each product and if an extended BUD date is assigned, the preparation must be tested for antimicrobial effectiveness. Consider one formula for magic mouthwash, which might have an aw of 0.73 and contains no preservatives. With no USP monograph, one would refer to Table 3 to determine that the BUD should be limited to 14 days when stored in the refrigerator. We are sure that pharmacists compounding blue mass syrup could have cared less about the activity of water in their concoctions. We wonder if they would have viewed mercury as a preservative.

       

      Compounders can assign non-aqueous dosage forms with an aw less than 0.6 a maximum BUD of 90 days for an oral liquid and 180 days for alternative routes.

       

      While the newly revised standards provide strong guidance on determining a CNSP’s BUD, compounders should only use its tables if no other stability information is available. The designated person is responsible for searching for stability information for each CNSP and determining if a CNSP can have a BUD beyond that specified in Table 2. If the designated person finds an extended BUD appropriate, compounding staff must test it for antimicrobial effectiveness. However, if compounding staff is following a United States Pharmacopeia- National Formulary (USP-NF) monograph for CNSP preparations, the BUD must not exceed that which is indicated in the monograph. Last, the CNSP’s components should drive the overall expiration date, which is not a change from the current standards.

      CONCLUSION

      Compounders face many of the same challenges today as they did in the 1800s. They were faced with a limited drug list, similar to a closed formulary in today’s world. They searched for alternative therapies, and they did, as we still do, face many drug shortages. The main difference is that we have advanced knowledge to make better products to keep patients safer.

       

      The time has come to designate your area, designate your person, and train your staff, including pharmacists who may not actually be compounding! Keep the designated area clear for compounding use only, if possible, and remove any unnecessary items before entering. Set up a cleaning routine for the entire space, including floors, walls, and shelving, and incorporate the routine into the daily workflow so it is never forgotten. Train your staff well to the new standards and reevaluate every 12 months. Look into the literature to determine the best BUD for each CNSP and when information is not available, use USP guidance for assigning a BUD date. Choose a designated person wisely, as they need to be responsible and organized with taking responsibility and accountability for all nonsterile compounding occurring in the facility.

       

      Remember, improvements in non-sterile compounding standards will make for higher quality and safer compounded non-sterile products for our patients and are enforceable come November 1, 2023.

      ABSTRACT

      Recently, it’s a rare day when the national news outlets and social media platforms don’t discuss medication-assisted weight loss. Semaglutide has become a social media sensation for its ability to help people–even people who do not have diabetes (its approved indication) lose weight. With celebrities reporting significant weight loss with off-label use of glucagon-like peptide-1 (GLP-1) receptor agonists, pharmacy teams are fielding questions and juggling prescriptions to deal with drug shortages. This continuing education activity provides basic facts about using GLP-1 receptor agonists for weight loss.

      INTRODUCTION

      Lifestyle modifications have been the mainstay of weight management for years. We’ve all heard the advice: Exercise more, eat less, limit fried foods and sugary drinks, and the weight should slowly disappear. As the weight comes off, you might have some setbacks but just keep tracking your foods and your success is right around the corner.

       

      If only it was that easy!

       

      Scroll any social media platform today and search the term, “#ozempicweightloss” and a plethora of joyful testimonials appear. Some videos have reports of people losing 17 pounds in 3 months or 64 pounds in a year with no cravings for food. “I can eat whatever I want!!” cried a satisfied user. It is as if the golden ticket has been found in all the candy bars ever produced and everyone is going to the candy factory!

       

      Although the recent media emphasis has been on semaglutide, and the Ozempic product primarily, other glucagon-like peptide-1 (GLP-1) receptor agonists have also been associated with weight loss to varying degrees. This continuing education activity’s primary focus is to clarify misinformation, highlight specific GLP-1s’ risks and benefits when used for weight loss, and answer frequently asked questions.

       

      WHAT ARE GLP-1 RECEPTOR AGONISTS?

       

      Major breakthroughs in the physiology of the pancreas occurred in the early 1900s.1 At that time, physiologists thought the nervous system had exclusive control of all bodily functions. That idea changed when two scientists, William Bayliss and Ernest Starling, discovered a chemical compound they named secretin. Released from intestinal mucosa, secretin stimulated the pancreas.2 Shortly after the discovery of the hormone insulin in 1921, research being conducted at the time primarily stimulated the pancreas to produce insulin by administering glucose via the intravenous route. However, when glucose was administered orally (allowing nutrients to travel to gastrointestinal areas), insulin levels improved substantially. This observation was known as the incretin effect. As a result, two insulinotropic hormones were later identified as incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) discovered in 1971 and glucagon-like peptide-1 (GLP-1) discovered in 1985.1,2

       

      Analyzing the venom of the Gila monster (Heloderma suspectum) in 1990, endocrinologist Dr. John Eng discovered a peptide that stimulated insulin release from the pancreas.3 Named exendin-4, this peptide was similar in structure and function to GLP-1 found in humans. One problem with GLP-1 was that when it is released into the body, dipeptidyl peptidase-4 (DPP-4). quickly inactivated it. Researchers then developed the DPP-4 inhibitors to allow GLP-1 to remain active for a longer period of time. However, synthetically producing GLP-1 receptor agonists (GLP-1RA) directly has extended the peptide’s life. Initial development resulted in twice daily and then daily administration (half-life of 13 hours) of GLP-1RAs. However, when researchers combined semaglutide with a free fatty acid side chain that was tightly bound to albumin, its half-life was increased substantially. The resultant half-life of 165 hours led to an advantageous injection administration schedule for semaglutide: once weekly.3,4,5

       

      Mechanism of Action

      As a class of medications, all GLP-1RAs share common mechanisms of action in the treatment of diabetes: stimulate the pancreas to secrete insulin, suppress the action of glucagon, and decrease gastric emptying.4 Scientists previously studied the effects of GLP-1 and noticed that the protein, when injected in rats, decreased appetite quickly.5 Once clinicians began using GLP-1RAs to treat diabetes in humans, they also observed weight loss due to decreased appetite, increased feelings of fullness, and reduced caloric consumption.4

       

      Researchers determined that the brain contained GLP-1 receptors. Weight loss was due to GLP-1RAs ability to travel to these receptors and influence specific areas of the hypothalamus that are key to controlling appetite, calorie consumption, satiety, and body weight.4 Among GLP-1RAs, semaglutide and liraglutide stimulate the highest amount of weight loss success.

      Adverse Drug Reactions and Boxed Warning

      GLP-1 agonists all have similar and common gastrointestinal adverse effects (nausea [~15–30%], vomiting [~10-15%], diarrhea [~5-10%], abdominal pain, constipation).6,7,8 Patients can use some strategies to possibly mitigate these adverse effects6,7,8:

      • Increasing the GLP-1 agonist dose slowly
      • Staying hydrated and increasing fiber
      • Avoiding high-fat foods and alcohol
      • Stopping eating when full (and eating only when hungry)
      • Spacing meals appropriately
      • Using short-term proton pump inhibitors or H2 blockers if needed

      Patients may also experience headache, fatigue, dyspepsia (gastrointestinal upset), dizziness, abdominal distension, eructation  (burping), hypoglycemia in patients with type 2 diabetes, flatulence, gastroenteritis, and gastroesophageal reflux disease.7 Clinicians should evaluate patients for gallbladder disease if cholelithiasis (gallstones) or cholecystitis (an inflamed gall bladder) is suspected.

       

       

      Reports of patients experiencing hair loss have surfaced recently from news and social media. Listed as an adverse reaction for Wegovy, but not for Ozempic, the Wegovy dose is much higher for treatment of weight loss.9 Some clinicians think that the rapid loss of weight triggers the body to conserve calories consumed for essential functions.9 Since patients eat less while taking the medications, their diet may consist of lower amounts of protein and minerals important for hair growth. Clinicians have seen hair growth resume once the body reaches a plateau in weight loss, therefore the loss of hair is not permanent.9

      These drugs also share a boxed warning for risks of pancreatitis and medullary thyroid carcinoma (cancer in the thyroid gland in its medulla, the calcitonin-producing area), which is rare.6 Patients with a personal history of pancreatitis or a personal or family history of medullary thyroid carcinoma must avoid these drugs.6

      These drugs also required an FDA approved Medication Guide whenever GLP-1RAs are dispensed. Pharmacy technicians can be very helpful to pharmacists if they check the patient’s bag and make sure that the Medication Guide is in it.

       

      Recent Shortages of GLP-1 Receptor Agonists

       

      The sensation of weight loss success for some has caused serious problems for other patients who have diabetes and are struggling to find medication at local pharmacies. Staff in community-based pharmacy practice are well aware of the semaglutide shortages that have occurred in the past year. Pharmacists and technicians should be able to explain the current drug shortages, adverse reactions, and FDA approved or off-label use to patients and other healthcare providers.

       

      Ozempic face”

       

      As social media and now news media have reported the success of dramatic weight loss, some users bemoan weight loss woes associated with use of GLP-1 agonists. The term, “Ozempic face,” introduced by a dermatologist in New York, describes the typical female patient who has lost a significant amount of weight on semaglutide but now needs (or wants) dermal fillers for her sagging facial structures.10 Patients complain about sagging skin and a gaunt appearance, two problems that follow the loss of facial fat after any harsh weight loss.

       

      Facial fat loss is common when patients lose weight, and when the weight loss is significant, patients will look older. Skin wrinkles and loosens—hallmarks of aging. Similar to weight loss from old-fashioned dieting, fat loss while taking GLP-1 agonists affects the entire body (not just the face). But patients on GLP-1 agonists for cosmetic weight loss fail to understand that they can’t just lose weight where they’d like to lose weight. The facial fat loss is distressing to them.10 Pharmacy teams need to know that “Ozempic face” is a slang term, and GLP-1 agonists don’t specifically target the face.11

       

       

      Weight Loss Blockbuster or Fad

       

      Over the past two years, celebrities and social media influencers have posted successful weight loss stories while using semaglutide and as a result, catapulted its popularity as a weight loss miracle.12 Questions remain as to how long the weight loss effect will last and if patients will gain the weight back once stopping the treatment. Novo Nordisk, semaglutide’s manufacturer, indicates weight loss can be sustained with long-term use. However, the data collected is limited by a time span of two to three years. Since people who pay out-of-pocket for semaglutide will pay around $1200 per month and some insurance companies may not cover the medication, pharmacists should counsel patients that once the medication is discontinued, weight gain is likely to occur and the weight gain might exceed the original amount lost.12

       

       

      FDA APPROVED AND OFF-LABEL USE

      In December of 2017, the FDA approved semaglutide (Ozempic) for the treatment of diabetes. As significant weight loss was observed, the Semaglutide Treatment Effect in People with obesity (STEP) studies produced promising weight loss data.13 As a result, the FDA approved semaglutide for an additional indication, weight loss, in June 2021 under the brand name Wegovy.

       

       

      Diabetes

      In patients with type 2 diabetes mellitus (T2DM), semaglutide is used in combination with diet and exercise to reduce blood sugar levels.14 In patients with T2DM who additionally have established cardiovascular disease, liraglutide and semaglutide are indicated to help lessen the risk of major cardiovascular incidents. Dulaglutide, liraglutide, and semaglutide also have beneficial effects on chronic and diabetic kidney disease.6 Patients who have a history of pancreatitis should avoid any member of the GLP-1RA class and they are not to be used as treatment for patients who have type 1 diabetes.

       

      Dosing semaglutide for the treatment of diabetes requires a period of time for dosage escalation to minimize adverse effects. The FDA has approved both subcutaneous and oral semaglutide (Rybelsus) dosage forms, but only the injectable version is approved for weight loss. Subcutaneously, semaglutide is initially dosed at 0.25 mg once weekly, and after four weeks the patient should increase to 0.5 mg weekly for four weeks. Doses of 1 mg and 2 mg are optional if glycemic control has not been achieved, however the 1 mg dose should also be used for a minimum of four weeks before increasing to the maximum 2 mg strength.6 Dosed on the same day of the week, injections can be dosed at any time of the day with or without regard to meals. Patients sometimes miss or forget their scheduled dosing day. If this occurs, patients should inject the dose within 5 days of the missed dose.6

       

      Patients who have diabetes and currently use metformin, sulfonylureas, thiazolidinediones, or insulin can use semaglutide in combination.  However, patients can administer semaglutide and insulin injections at the same time and in the same areas of the body, but not close together; they must never mix them together in the same syringe.14 Hypoglycemic episodes are possible when using a sulfonylurea and/or insulin with semaglutide. Pharmacists therefore should remind patients of the signs and symptoms of hypoglycemia when these drugs are used together. Prescribers may need to adjust the dose of insulin and/or a sulfonylurea when starting semaglutide.6

      Affecting 70% of American adults, obesity and being overweight contribute to a variety of complications and have reduced quality of life.15 Debilitating and expensive disease states associated with obesity include: T2DM, cardiovascular disease, osteoarthritis, sleep apnea and cancer.13,15 Since obesity has roughly tripled worldwide from 1975 to 2016, investigating the reasons for the rise in prevalence and finding solutions is of utmost importance to prevent and treat obesity.16

       

      The access and ease of inexpensive prepared high caloric foods, limited physical activity, and sedentary life styles are factors that have contributed to the rise of obesity.17 As mentioned, treatment typically has concentrated around the modification of these lifestyle habits.18 Although the weight reduction is usually moderate in magnitude, it is recovered over time (yes, that means that people gain the weight back!).13

       

      Anti-obesity medications have been added to lifestyle modifications. Discouraged by adverse drug reactions, contraindications, cost, and moderate weight loss results with weight that is regained over time, many patients and prescribers are hesitant to consider these treatment options.16

       

      Maintaining weight loss has proved equally difficult due to the regulatory centers in the brain that control appetite. Increased hunger and abnormal satiety signals controlled by neuroendocrine pathways have been discovered in the hypothalamus.16 Researchers have also identified levels of hormones that regulate weight in the hypothalamus. These hormones (leptin, ghrelin, peptide YY, and GIP) play a role in counteracting weight loss after dieting and lead to regain of weight.17, 16

       

      Once semaglutide was approved for the treatment of diabetes, clinical trials focused on weight loss. The STEP trials were phase 3 studies implemented to evaluate the safety and efficacy of semaglutide 2.4 mg subcutaneously once weekly injections for 68 weeks. Patients enrolled in the studies were adults with obesity or overweight, a mean age of 46.2 to 55.3 years, mean BMI of 35.7 to 38.5 kg/m², and were mostly female (mean: 74.1% to 81.0%) for five of the trials.13All studies included lifestyle interventions at varied intensities.13, 18 In one of the larger studies that compared semaglutide with placebo, semaglutide was associated with a 12.4% loss of body weight.15As a result of the  ≥ 5% in weight loss exhibited in the studies, the FDA approved semaglutide for chronic weight management.18,15 The approval came in June of 2021, and the manufacturer marketed semaglutide as Wegovy.

       

      The STEP 8 trial compared once-weekly semaglutide to once-daily liraglutide and enrolled 338 adult patients with 126 receiving semaglutide 2.4 mg, and 127 participants receiving liraglutide 3 mg. Participants were overweight or obese, without diabetes, had a mean BMI of 37.5, and most had 0-2 comorbidities with dyslipidemia and hypertension being the most frequent.19, 18 The primary results at 68 weeks reported an estimated mean change in body weight at -15.8% with semaglutide, and -6.8% with liraglutide.19 Based on data from this STEP study, the researchers concluded semaglutide is far superior to liraglutide when used for weight loss and had significantly improved cardiometabolic risk factors.19, 18

       

      The most frequent adverse side effects reported in the STEP studies were gastrointestinal disorders. Most gastrointestinal side effects were considered mild or moderate in severity and usually were most prominent during the dose titration phase.19 In the STEP 8 study, semaglutide (84.1%) reported a higher occurrence of gastrointestinal events than liraglutide (82.7%).19  Other side effects reported were hypoglycemia, acute pancreatitis, gallbladder disorders that generally resulted in cholelithiasis (gall stones), malignant neoplasms (cancer), change in pulse and injection site reactions.18, 19

       

      SIDEBAR: Alcohol use disorder potential

      As patient use of semaglutide has expanded over the past several years, a side effect has emerged that is surprising many clinicians. Patients have reported an abrupt loss in the desire to drink alcohol, almost to the point of repulsion for some patients. GLP-1RAs are known to decrease the desire, enjoyment, and consumption of fatty foods in humans, but observations that patients began to decrease alcohol consumption was unexpected. Although studies to date have observed a reduction of alcohol in rats, mice, and monkeys when receiving GLP-1RAs, reliable researchers avoid extrapolating results from animal studies directly to humans, especially since humans tend to consume more alcohol than animals.20 Since several patients have reported decreased intake of alcohol and data from animal models reflect these results, researchers are starting to investigate GLP-1RAs effect on patients who have alcohol use disorder (AUD).

       

      Existing studies on GLP-1RAs effect on AUD in humans are minimal. A recent study published from Denmark compared the use of a different GLP-1RA, exenatide 2 mg versus placebo in patients with AUD. Researchers were looking to determine if exenatide reduced the amount of heavy drinking days. At the same time, functional MRI brain scans were also completed during the study that focused on areas involved in addiction and reward centers of the brain. Administered once weekly to 127 patients along with cognitive behavior therapy for 26 weeks, exenatide failed to show a decrease in heavy drinking days.21  However, in a subgroup of obese patients (BMI > 30 kg/m2) heavy drinking days and total alcohol intake was reduced.21 Brain scans revealed weakened alcohol cue reactivity and lower dopamine transporter availability for those patients in the exenatide group.21

       

      Ongoing phase two clinical trials are studying the effects of semaglutide on patients with AUD.22 Since semaglutide usage and availability have increased with approved indications for diabetes and obesity, researchers are continuing to investigate this drug class for potential promising new therapies.

       

      Product information

      When used for chronic weight management, semaglutide (Wegovy) is approved in addition to a reduced calorie diet and increased physical activity.7, 15 Semaglutide is indicated for patients who meet one of the following criteria: BMI of 30 kg/m² or greater, or patients who have a BMI of 27 kg/m² with at least one comorbid weight related condition (cancer, cardiac disease, diabetes, dyslipidemia, obstructive sleep apnea).7, 15 Available in a prefilled pen that contains one dose, semaglutide is a clear and colorless liquid that can be injected into the upper arm, lower stomach or upper thigh.7 Semaglutide should be stored in the refrigerator between 36°F to 46°F (2°C to 8°C).7 If the pen has been frozen, exposed to light, or heat above 86°F (30°C), the pen should be discarded. The pen remains stable and active for 28 days once removed from refrigeration. Each pen contains the exact dose to be delivered with the needle located inside each pen, therefore each pen should be disposed of in a sharps container.7

       

       

      Drug shortages, alternatives for therapy

      Shortly after marketing Wegovy, the facility hired by Novo Nordisk to fill syringes was cited by the FDA for issues with current good manufacturing processes.23, 24 As a result, deliveries and manufacturing of Wegovy was halted in December of 2021.24 At the same time, staggering demand for the drug was reported by the manufacturer mainly due to news and social media platforms announcing the success of several celebrity weight loss stories. As a result of the Wegovy shortage, prescribers started to write for Ozempic off label in an effort to treat obesity and therefore depleted the supplies of Ozempic.24 At the end of 2022 and early 2023, Novo Nordisk announced that supply issue resolution for Wegovy was on the horizon and that production of the drug was being increased. Due to residual and increasing demand though, some supply issues might continue sporadically but over time distribution centers and pharmacies should receive more drug product in the months ahead.25

       

      CONCLUSION

      Probably the first drug to be considered a social media sensation, semaglutide’s entrance into the realm of prescription weight loss treatments has been filled with anticipation, fame, demand, intrigue, and acceptance. Lifestyle management will continue to play a role in losing and maintaining weight loss, with or without a GLP-1RA used in treatment for weight management. Long term use of semaglutide seems to be necessary to maintain a healthy weight but more research is necessary. Gastrointestinal side effects are seen as the most prevalent adverse effect, leading some patients to discontinue the drug. As availability of semaglutide increases due to resolution of the issues that halted production, price, and lack of coverage by insurance plans continues to be problematic for some patients. This is an area where pharmacy technicians can help by looking for coupons or patient assistance programs.

       

      Researchers continue to investigate the various effects seen as a result of usage of semaglutide. Investigators are hopeful of finding new treatments for patients that are struggling with alcohol use disorder and addictive behaviors. GLP-1RAs will continue to be in the headlines for years to come. Pharmacists and technicians hold the golden ticket of information by helping patients and providers understand this unique class of medication’s history, mechanism of action, dosing, side effects, storage requirements, pricing and potential treatments being investigated.

      ABSTRACT

      The gallbladder—a member of the biliary system—is responsible for bile secretion into the digestive tract. It was more useful centuries ago when the human diet was largely carnivorous and high in fat, its role in digestion today is less essential. This makes removal of the organ to treat gallbladder disease (GBD) quite commonplace. Although surgery is first line GBD treatment, pharmacy teams should remain involved in care for patients with this condition. Pharmacy involvement is especially important post-gallbladder removal. This continuing education activity describes the function of the gallbladder, risk factors for and pathogenesis of GBD, treatment approaches for GBD, and how to optimize care for patients with the disease and post-gallbladder removal.

      INTRODUCTION

      Gallbladder disease (GBD; see Sidebar: Types of Gallbladder Disease) is the most common surgical emergency, responsible for 600,000 surgeries per year in the United States.1 Cholelithiasis, or gallstones, is one of the most common and costly gastrointestinal diseases, affecting more than 20 million Americans annually.2 An estimated 115 of every 100,000 of the world’s population will undergo gallbladder removal surgery every year.3

      GBD is influenced by genetic and environmental factors, diet, physical activity, and nutrition. The healthcare team should encourage patients to incorporate healthy habits into their lifestyles to reduce the risk of GBD. This continuing education activity will discuss GBD pathology, risk factors, treatment, considerations post-cholecystectomy, and the pharmacy team’s role.

       

      GALLBLADDER DISEASE

      The Gallbladder

      The gallbladder is the small pear-shaped organ located in the right upper quadrant (RUQ) of the abdomen beneath the liver. It is part of the biliary system, which is a series of ducts in the liver, gallbladder, and pancreas that drain into the small intestine.4 The gallbladder acts as a storage pouch for up to 50 mL of bile, also known as “gall.”5 Gall became a synonym for bile in the Middle Ages and also meant “embittered spirit.”5 In the late 19th century, gall was used to describe a person having boldness or insolence.4

      Bile is a yellowish-brown alkaline surfactant (substance that decreases surface tension) continuously produced by the liver.1,2 It is composed of cholesterol, bilirubin, water, bile salts, phospholipids, and ions. The common bile duct carries bile from the liver to the gallbladder. Fatty foods and proteins released from the stomach into the small intestine stimulate the gallbladder to empty bile into the duodenum via the sphincter of Oddi, which facilitates digestion. Bile salts emulsify lipids in the intestines allowing absorption of dietary fats such as cholesterol and fat-soluble vitamins. Unused bile salts return to the gallbladder through the distal ileum and portal circulation.1,2

      The gallbladder was probably more valuable centuries ago.5 Primitive humans were carnivorous hunters; meals were large, few, and far between.5 The gallbladder would have been crucial for digestion of large, high fat meals. The organ wasn’t considered nonessential until the late 1600s, after two Italian doctors discovered that animals could thrive without it.1 This discovery was forgotten until a German physician successfully performed the first cholecystectomy (surgical removal of the gallbladder) in a human in 1878.1,6 Figure 1 describes a brief history of the gallbladder, gallstones, and cholecystectomy beginning in the 15th century.

      Today, the gallbladder assists in digestion of fat-soluble vitamins, proving important even for vegetarians.5 People can still live a healthy life after gallbladder removal; however, the risk of hepatic problems increases due to impaired fat digestion.5

      This continuing education activity will focus on gallstones and their complications, which may include cholecystitis, choledocholithiasis, and cholangitis. Cholecystectomy (gallbladder removal) is the treatment mainstay for gallstones and pharmacist intervention is most valuable post-cholecystectomy.

       

      Gallstones and Acute Cholecystitis

      The most common gallbladder disease is gallstones.7 Gallstones commonly form from imbalances in bile constituents and biliary sludge (solids precipitated from bile) caused by slowed gallbladder motility or altered hepatic cholesterol metabolism. Hardened cholesterol or bilirubin become saturated in bile and crystalize, like rock candy, and can lodge in the common bile duct.7 Gallbladder hypomotility leads to delayed emptying, resulting in the formation of biliary sludge and consequently, gallstones.7

      Bilirubin is a substance found in bile resulting from red blood cell breakdown in the liver. It is normally eliminated through the feces. Gallstones caused by bilirubin, or “pigment stones”, are rare and only account for approximately 10% of all gallstones.8 Pigment stones are commonly seen in individuals with blood disorders, such as sickle-cell anemia.8 Approximately 75% of gallstones in Western countries contain cholesterol as their major component.9

      The presence of stones in the gallbladder is called cholelithiasis. Most patients with gallstones are asymptomatic and may not have any attributable symptoms during their lifetime.8 Asymptomatic cholelithiasis does not require treatment as the risk of symptom development is only about 10% at five years.8

      Cholelithiasis becomes acute cholecystitis when gallstones block the cystic duct, causing the gallbladder to become inflamed and patients to become symptomatic. Biliary pain—also known as biliary colic—is the most common symptom of cholecystitis. Epigastric (upper-middle abdomen) pain lasting from 30 minutes to several hours radiates around or through the back and may be accompanied by heartburn, bloating, nausea, and/or vomiting. The sharp, stabbing pain generally follows food intake and peaks after the first hour. It is characteristically steady and is severe enough to interfere with activities of daily living. The pain is not relieved with a bowel movement. Women often describe biliary pain as being worse than childbirth.2,8

      Cholecystitis pain from an acute episode usually subsides over one to five hours as the stone dislodges.3,10 The likelihood that patients experience repeated symptomatic episodes from their gallstones is approximately 38% to 50% annually.8 More than 90% of patients presenting with a single episode of biliary colic have recurrent pain within 10 years.13

      Ultrasound is the best test for diagnosing gallstones and finds most patients with an average of two to 20 stones. The record-setting number of stones was found in England in 1987; a female patient had 23,530 stones removed.5 Computerized tomography (CT) can also be used for diagnosis, but it is less accurate than other imaging methods, detecting approximately 75% of gallstones.2 Providers can also diagnose by the presence of Murphy’s sign, or pain upon inhalation when the inflamed gallbladder meets the examiner’s hand.8 Other diagnostic markers include elevated liver function tests, white cell count, erythrocyte sedimentation rate, and C-reactive protein.8 Patients presenting with acute cholecystitis may have experienced several bouts of biliary colic before diagnosis.

      Acute cholecystitis diagnosis typically requires admission for pain management and intravenous (IV) fluid rehydration. Nonsteroidal anti-inflammatory drugs (NSAIDS) like ketorolac, diclofenac or indomethacin combat inflammation and promote speedy recovery.8 NSAIDS are generally preferred to narcotic analgesics as they are equally effective with fewer adverse effects.2 A study of 324 patients given IV ketorolac or meperidine showed both drugs offered similar pain relief but patients in the NSAID group reported fewer adverse effects.2 Patients receive broad-spectrum antibiotics (e.g., ciprofloxacin, cefuroxime) to prevent or treat bacterial infection.8

      Failure to properly treat cholecystitis can lead to severe inflammation, gangrene, sepsis, and life-threatening gallbladder perforation. Cholecystitis can also lead to gallstone pancreatitis if stones in the sphincter of Oddi are not cleared and block the pancreatic duct.2

      Chronic Cholecystitis

      Repeated episodes of cholecystitis or chronic irritation from gallstones can lead to chronic cholecystitis.11 Chronic cholecystitis more often presents with cholelithiasis (calculous) but can also exist without gallstones (acalculous). Symptomatic patients usually present with dull RUQ pain that radiates around the waist to the middle back. Most patients are afebrile.11

      While acute cholecystitis symptoms are sharp and abrupt, chronic cholecystitis symptoms usually develop and worsen over weeks to months.11 Lab values normally elevated in acute disease may not be in chronic disease and therefore cannot be used in diagnosis. Ultrasound of the RUQ is the best diagnostic tool to evaluate the gallbladder for wall thickening and inflammation. Elective cholecystectomy is the preferred treatment for chronic cholecystitis. Patients who are not eligible for or who prefer not to undergo surgery should be closely monitored. A low-fat diet and other lifestyle modifications can help reduce symptom frequency.11

      Pharmacists should recognize the differences between presentations of acute versus chronic cholecystitis and refer patients to the nearest emergency department if symptoms are severe.

      Choledocholithiasis and Cholangitis

      Choledocholithiasis, or common duct stones, are gallstones that have migrated from the gallbladder to the common bile duct via the cystic duct. Approximately 8% to 16% of patients with symptomatic gallstones will also have common bile duct stones.8 Common duct stones can be asymptomatic or may lead to complications such as gallstone pancreatitis or acute cholangitis. Cholangitis is inflammation of the biliary system that causes fever, jaundice, and abdominal pain (Charcot triad).8 Charcot triad becomes Reynolds pentad when hypotension and altered mental state are also present.8 These symptoms develop due to bile stasis and bacterial infection in the biliary tract.

      Cholangitis is most commonly caused by gram-negative (Escherichia coli [25% to 50%], Klebsiella spp. [15% to 20%], Enterobacter spp. [5% to 10%]) intestinal bacteria, and less often by gram-positive bacteria (Enterococcus spp. [10% to 20%]).8 Patients require prompt treatment with IV antibiotics such as a broad-spectrum cephalosporin or ciprofloxacin.8 Pharmaceutical intervention should be followed by stone removal to prevent septicemia (systemic blood infection), which can be fatal.  Most clinicians recommend that common bile duct stones be removed once discovered, even when asymptomatic.8

      Risk Factors

      Several genetic and environmental factors contribute to gallstone development. Patients with first-degree relatives with history of cholelithiasis are at a three times higher risk of gallstones.8 Approximately 60% of patients with acute cholecystitis are female, but the illness is generally more severe in males.2 Women experience a higher prevalence because of estrogen’s effects on cholesterol metabolism.12 Estrogen increases cholesterol synthesis and decreases bile acid production.12 Progesterone in pregnancy decreases gallbladder contractility leading to stasis, making gallstones 10 to 15 times more common in women who have been pregnant.8,12 Women with history of biliary colic, gallstones, and the like should be aware of how hormones may affect their risk for recurrence. This is valuable information for pharmacists to consider and an appropriate place to intervene and educate.

      European and American populations are more likely to develop gallstones, and Black people of African descent are least likely. Prevalence is highest in Native American populations, with 60% incidence in the Pima Indian populace of southern Arizona.8 Table 1 summarizes risk factors for GBD.2,8,13

      Glucagon-like peptide 1 (GLP1) receptor agonists (GLP-1RAs) are notable for their glucose control and cardiovascular risk reduction for patients with type 2 diabetes mellitus and more recently, for weight loss. Their link to GBD is controversial as GLP1 inhibits gallbladder motility and delays gallbladder emptying.14 A recent systematic review and meta-analysis of 76 randomized clinical trials shows an association between GLP-1RA use and elevated GBD risk. The risk for gallbladder or biliary diseases were more prominent with higher doses, longer duration, and when used for weight loss.14 Clinicians should discuss the benefits of using these hypoglycemics for type 2 diabetes or weight loss and whether they outweigh the risk for GBD. Pharmacists can educate patients initiating GLP-1RAs about their benefits, risks, and implications with past medical history of or additional risk factors for GBD. Multiple GLP-1RAs are available in varying doses and pharmacists should continue to counsel patients as doses are increased over time.

      Chronic use of gastric acid suppressants may cause cholelithiasis.15 These drugs impact gut microbiome and may slow gallbladder motility leading to delayed gallbladder emptying. A recent prospective cohort of 0.47 million participants found that regular use of proton-pump inhibitors (PPIs) and histamine-2-receptor antagonists (H2RAs) resulted in increased cholelithiasis risk.15 Physicians should be aware of this association when prescribing these medications, especially for patients requiring long-term use or those already at high risk for gallstones. Pharmacists should keep these risks in mind when filling prescriptions for their patients on long-term or high-dose H2RAs and PPIs.

      Ketamine abuse has been associated with chronic biliary colic. Ketamine was developed in 1962 as an anesthetic.16 “Street ketamine”, a close analogue of ketamine, is commonly used for its euphoric effects. Ketamine’s onset of action after oral ingestion is about ten minutes and its hallucinogenic effects are short acting, lasting up to two hours. The most common signs of ketamine abuse are hypertension, tachycardia, and abdominal tenderness. Ketamine abuse is also associated with impaired consciousness, dizziness, abdominal pain, and lower urinary tract symptoms.16 Case reports have shown ketamine abusers presenting with severe bladder dysfunction and recurrent episodes of epigastric pain due to a dilated common bile duct not associated with gallstones.16 Clinicians should collect detailed drug histories for patients presenting with recurrent abdominal pain, namely biliary colic.

      Diets characterized by increased caloric intake with highly refined sugars, high fructose, low fiber, high fat, and consumption of fast food increase the risk of gallstone formation.9 Nutrition and lifestyle changes may be beneficial in the prevention of gallstones. Increased physical activity, consuming smaller more frequent meals, and “heart healthy” diets low in cholesterol and fat and high in fiber can reduce risk of cholelithiasis.7 Fat should not be completely cut out of the diet as too little fat can also precipitate gallstone formation.

      Weight loss can reduce gallstone risk, but rapid weight loss achieved by low-calorie diets (less than 800 kcal/day) or bariatric surgery can cause gallstones.2,9 Patients should seek professional advice before starting diets promoting very low caloric or high fat intake to achieve rapid weight loss (i.e., Atkins, ketogenic). Pharmacists should be aware of patients who have recently undergone bariatric surgery or are taking drugs or supplements for weight loss. These patients may be at a higher risk for gallstones, especially those with past medical histories of GBD or abdominal colic symptoms.

      Some foods and medications seem to be associated with a reduced risk of gallstones:

      • Statins alter bile cholesterol and thus affect gallstone formation, suggesting a role in prevention. While the relationship between statins and gallstone formation is conflicting, studies report reduction in symptomatic gallstone disease with statin use.17
      • Ezetimibe, a selective NPC1L1 inhibitor, has been associated with a reduced incidence of cholesterol gallstones in animal studies. The mechanism involves reduced amounts of absorbed cholesterol, decreasing biliary cholesterol saturation, and in turn, reduced rate of cholesterol gallstone formation.12
      • Vitamin C supplementation has been shown to reduce gallstone prevalence. Researchers have studied vitamin C supplementation’s effects in gallstone formation in guinea pigs; those deficient in vitamin C more often develop gallstones. An observational study of a randomly selected population in Germany (n = 2129) showed a positive correlation between regular vitamin C intake and a reduced gallstone incidence.18
      • Coffee consumption may also offer a protective effect against gallstone formation. Studies suggest coffee stimulates cholecystokinin release, enhancing gallbladder contractility, thereby reducing bile cholesterol crystallization. A 2019 observational analysis published in the Journal of Internal Medicine found a 23% decrease in gallstone formation in subjects consuming six or more cups of coffee daily.19
      • A small study conducted in Spain shows that regular consumption of olive oil containing monounsaturated and polyunsaturated omega-6 fatty acids may prevent gallstones. Similarly, fish (omega-3 fatty acids) and fish oil may reduce triglycerides and prevent gallstones. A group of participants with hypertriglyceridemia taking fish oil supplements for a seven-week study in the Netherlands experienced improved gallbladder motility and a decrease in triglycerides.10

      TREATING GALLBLADDER DISEASE

      Endoscopic retrograde cholangiopancreatography (ERCP) is the most common way to identify and remove common duct stones. ERCP is minimally invasive and carries the risk of acute pancreatitis.8 This diagnostic tool may also identify duct strictures at which time stents are placed to reduce obstruction and improve biliary flow.8,10 Timely stent removal (within three to six months) is crucial to prevent occlusion, stent migration, or cholangitis.22 Cholecystectomy is the definitive treatment for symptomatic gallstones and should commence within 48 hours of symptom onset during the acute inflammatory process, before tissue thickening or scarring develops.8,10

      Surgical Intervention: Cholecystectomy

      The first gallstone removal surgery was a coincidence. In the mid-19th century, a physician was performing investigative surgery on a female patient, and when he cut into her gallbladder, several bullet-like objects spilled out.5 The first planned gallbladder removal was performed 15 years later.5 Before the early 1900s, the surgery was performed through an incision in the RUQ (Kocher’s incision, named after Emil Theodor Kocher, a Swiss physician and medical researcher who performed the first successful cholecystectomy in 1878).6,8 This invasive procedure was outmoded a few years after Erich Muhe, a German surgeon, performed the first laparoscopic cholecystectomy in 1985.8 Today, surgeons perform more than 98% of cholecystectomies laparoscopically, over 70% of which are outpatient day surgeries.8

      Cholecystectomy is associated with fewer gallbladder-specific complications and shorter length of hospital stay when surgery is elective or performed as a single emergency visit without previous surgical admissions.3 A population-based cohort study of outcomes following surgery for benign GBD showed poorer outcomes and risk of readmissions with delayed cholecystectomy. Many studies define emergency or early surgical intervention as operations performed within 48 to 72 hours of symptom onset. A study of 14,200 patients in Canada discovered patients experienced fewer complications when surgery was performed within seven days of hospital admission.3 These studies show value in offering emergency surgery over delaying cholecystectomy for patients presenting with benign GBD.3

      Antibiotic prophylaxis is not routinely recommended for low-risk patients undergoing elective laparoscopic cholecystectomy.13 High-risk patients (age older than 60, type 2 diabetes, acute colic within 30 days of surgery, jaundice, acute cholecystitis, or cholangitis) may benefit. Providers should limit prophylaxis to IV cefazolin 1 g as a single dose one hour prior to surgery.13

      Several studies suggest that pain management before or during, and after laparoscopic cholecystectomy can reduce post-operative pain. A 2018 review of 258 randomized control trials recommended a basic analgesia technique: acetaminophen plus an NSAID or cyclooxygenase-2 inhibitor with local anesthetic infiltration.21 Opioids are reserved for breakthrough pain.21

      Patients are generally discharged a few hours after surgery. Surgeons should be on alert for early signs of complications if there is divergence from the usual course of rapid recovery post-op. Extreme pain shortly after surgery may indicate intra-peritoneal leakage of bile or bowel contents.8 Persistent hypotension (low blood pressure) and pain can suggest bleeding. Re-laparoscopy may be necessary to identify and repair these problems and is preferred to diagnostic imaging.8

      Removal of the gallbladder will not cause weight loss/gain or vitamin deficiencies. Patients should be able to tolerate foods they couldn’t before surgery, but providers should advise them to add those foods back into their diet very slowly. Following gallbladder removal, the liver will continue to make bile, but instead of storing it in the gallbladder, it will drain into the stomach and small intestines. Patients might experience three to five days of soreness post-op and are expected to fully heal within four to six weeks.7

      Diarrhea and bloating due to alternation of biliary flow are common short-term occurrences after surgery.22 A small percentage (1% to 2%) of patients will have loose stools each time they eat greasy or high-fat meals.7 A cystic duct remnant is also possible, potentially leading to stone formation, causing Mirizzi syndrome. Mirizzi syndrome is characterized by fever, jaundice, and RUQ pain due to common hepatic duct obstruction caused by compression from the impacted stone in the remnant cystic duct.22 Endoscopic removal of the stone may be adequate. In rarer cases, surgical excision of the remnant duct may be necessary to prevent further complications.22

      Pharmacologic and Other Non-Surgical Interventions

      Nonoperative methods exist for patients unwilling or unable to undergo surgical intervention. Contraindications for laparoscopic cholecystectomy include10,13

      • Absolute: gallbladder cancer (see Sidebar: Gallbladder Cancer), general anesthesia intolerance, giant gallstones, morbid obesity, uncontrolled bleeding disorder
      • Relative: advanced cirrhosis/liver failure, bleeding disorder, peritonitis, previous upper abdominal surgeries, septic shock

      Gallbladder Cancer20

      Gallbladder cancer is a rare malignancy but accounts for almost 50% of biliary cancers. Biliary cancers have a poor five-year survival rate and a high recurrence rate. Factors affecting prognosis are stage at discovery, tumor location, operability, response to chemotherapy, and presence and location of metastases. Early-stage gallbladder cancer may be curable with surgical resection.

       

      Oral bile acid dissolution drugs include ursodeoxycholic acid (ursodiol) and chenodeoxycholic acid (chenodiol).23 Table 2 lists dosing and adverse effects of these medications. Smaller gallstones (0.5 to 1 cm) may be better suited for pharmaceutical intervention but may take up to 24 months to dissolve.2 Ursodiol is preferred over chenodiol due to its safer adverse effect profile. Use-limiting adverse effects of chenodiol include dose-dependent diarrhea, hypercholesterolemia, hepatotoxicity, and leukopenia.2 Recurrence rate is more than 50% and fewer than 10% of patients with symptomatic gallstones are candidates for this treatment.13

       

      Table 2. Oral Bile Acids2,23,24

      Drug Dosage Duration Adverse Effects
      Ursodiol

      (Actigall)

      8-10 mg/kg/day given in 2-3 divided doses Symptom relief after 3-6 weeks, results may take 6-24 months, continue for 3 months after documented dissolution Dyspepsia (>10%), nausea, vomiting, pruritis, headache, diarrhea, dizziness, constipation
      Chenodiol (Chenodal) 250 mg twice daily for 2 weeks, increase dose by 250 mg/day weekly until maximum tolerable dose reached (13-16 mg/kg/day in 2 divided doses) Discontinue if no response by 18 months, safety not established beyond 24 months Dose-dependent diarrhea* (>10%), hypercholesterolemia, leukopenia, increased serum aminotransferase

      * If diarrhea occurs, reduce dose and restart at previous dose when symptoms resolve.

       

      Extracorporeal shock wave lithotripsy is a noninvasive option for symptomatic patients.13 Complications such as biliary pancreatitis and liver hematoma are rare, however stone recurrence is common. Recent studies show this procedure is beneficial for large pancreatic and common bile duct stones with similar pain relief and duct clearance outcomes compared to surgery.13

      The initial approach for pregnant women with symptomatic gallstones is supportive care.13 Meperidine is the choice agent for pain control as NSAIDs are not recommended in pregnancy.13 Chenodiol is contraindicated in pregnancy.24 Ursodiol has been used in pregnant patients for intrahepatic cholestasis; safety and efficacy of use for gallstones has not been studied.13,23 Laparoscopic cholecystectomy, when indicated, is safe in all trimesters.13

      POST-OPERATIVE CONSIDERATIONS AND THE PHARMACY TEAM

      Post-Cholecystectomy Syndrome

      Persistent or delayed onset abdominal pain after laparoscopic cholecystectomy may indicate post-cholecystectomy syndrome (PCS).22 Additional PCS symptoms include fatty food intolerance, nausea, vomiting, diarrhea, heartburn, indigestion, flatulence, and jaundice. PCS often occurs in the post-operative period but can present months or years after surgery.22 Cholecystectomy carries a low mortality risk, but approximately 10% of patients undergoing cholecystectomy each year develop PCS.22 The risk increases with urgent surgeries and 20% of patients will develop PCS regardless of choledochotomy (surgical incision of common bile duct).22

      PCS etiologies can be extra-biliary (pancreatitis, pancreatic tumors, hepatitis, esophageal diseases, mesenteric ischemia, diverticulitis, peptic ulcer disease) or biliary (bile salt induced diarrhea, retained calculi, bile leak, biliary strictures, stenosis, sphincter dyskinesia) in nature.22 Pathophysiology is related to alterations in bile flow and bile is the main trigger for patients with gastroduodenal symptoms or diarrhea.

      The likelihood of diarrhea post-cholecystectomy ranges from 2% to 50% according to various studies.25 Diarrhea usually improves or resolves over the course of weeks to months. As discussed, in the gallbladder’s absence, bile flows straight from the liver into the small intestine continuously. This redirection of bile flow can overwhelm the ileum’s capacity for reabsorption, leading to increased bile acids in the colon and subsequently cholerheic diarrhea (also known as bile acid diarrhea).25 Patients may respond to treatment with bile acid sequestrants, including cholestyramine and colestipol.25

      Bile acid sequestrants release chloride and bind bile acid in the intestines, preventing bile acid reabsorption. The drugs do not leave the gastrointestinal tract and are eliminated in the feces. They are indicated for hypercholesterolemia but patients use them off-label for chronic diarrhea due to malabsorption (Table 3). The most common adverse effect of bile acid sequestrants is constipation, which occurs in more than 10% of patients.26,27 Clinicians should instruct patients to drink plenty of fluid and increase dietary fiber. Most adverse effects are gastrointestinal-related (e.g., abdominal pain, flatulence, bloating, anorexia, nausea, vomiting, dysphagia), and others include26,27

      • Cholestasis and cholecystitis (with colestipol only)
      • Dental bleeding and caries
      • Diuresis, dysuria, and burnt odor to urine
      • Edema
      • Worsened hemorrhoids

      Bile acid sequestrants bind vitamin K and folate so prescribers should monitor for deficiencies of both. Patients should supplement with folate. Patients may supplement with vitamin K; however preexisting coagulopathy is a contraindication. These drugs should be used with caution in patients with renal insufficiency.26,27

      *May cause tooth discoloration or enamel decay. GI, gastrointestinal.

       

      PCS is a temporary diagnosis until further investigation establishes organic or functional diagnosis.22 Misdiagnosis of preexisting conditions is possible. The healthcare team should order a complete blood count and consider patients re-presenting with ongoing or new-onset abdominal pain post-cholecystectomy for CT scan.8 Presence of gas and fluid in the gallbladder bed may be normal but fluid or gas build-up elsewhere may indicate a bile leak. Elevated liver function tests may also suggest a bile leak or retained common bile duct stone. The most common cause of PCS is the presence of stones in the biliary tree.10 ERCP, both diagnostic and therapeutic, is the most common procedural approach to PCS.22

      Medication: Treatment Goals

      Pharmacologic treatment goals in GBD are to prevent complications and reduce morbidity.22 Administration of bulking agents like psyllium fiber can help patients with symptoms of irritable bowel syndrome (IBS) and/or diarrhea. Psyllium husk (Metamucil, Benefiber) is an over-the-counter (OTC) option for patients looking to increase fiber intake. It is usually used to treat constipation and works by stimulating intestinal contractility, speeding up the movement of stool through the colon.28 Psyllium can also treat diarrhea by soaking up excess water from the intestines, bulking stool, and promoting regularity.28 Psyllium may reduce absorption and effectiveness of many medications; it is important that patients seek pharmacist counseling before initiating a psyllium fiber regimen.

      Antispasmodics (e.g., loperamide) may help patients with IBS symptoms like cramping. Cholestyramine may help symptoms of diarrhea alone. Antacids (Maalox, Mylanta, Tums), H2RAs (e.g., famotidine), and PPIs (e.g., esomeprazole, lansoprazole, omeprazole) can improve gastritis or gastric reflux symptoms by reducing acid production.22 One study showed a correlation between dyspeptic symptoms and gastric bile salt; these patients may benefit from bile acid sequestrants.22 Patients should consult their gastroenterologist for recommended dosing of these drugs, as they may vary depending on clinical presentation and severity of symptoms.

      The Pharmacy Team’s Role

      Pharmacists and pharmacy technicians are integral members of the healthcare team. Pharmacists can educate patients about GBDs, the risk factors for their development, and how to mitigate them with a proper diet and exercise.

      Pharmacy technicians can help by directing patients in the right direction when looking for OTC antacids, fiber supplements, or anti-diarrheal agents. Many patients may not ask questions about OTC products before purchase. Pharmacy technicians are often the patients’ first point of contact in the pharmacy and should ask open-ended questions at the register before or during the transaction.

      Patients should use the products as directed by their gastroenterologists. Pharmacy technicians should refer patient questions relating to administration, dosing, adverse effects, and drug interactions to the pharmacist on duty. Consider possible scenarios that may arise in the pharmacy and how pharmacy technicians and pharmacists should approach them:

      • Mark is a pharmacy technician at XYZ Pharmacy. Jaclyn enters the pharmacy, approaches the pick-up window, and places several OTC items on the counter. She states she would like to pick up a prescription her doctor called in today. Mark retrieves Jaclyn’s prescription and notices it is for omeprazole 40mg. The items on the counter include Tums, famotidine 20mg, docusate sodium 100mg, and lansoprazole 30mg. Mark knows that omeprazole and lansoprazole are in the same drug class. What questions can Mark ask Jaclyn? Should Mark involve the pharmacist?
      • Jaclyn comes back to the pharmacy a week later to pick up a prescription for cholestyramine. She wants to know if she can take this with omeprazole and famotidine. Mark refers Jaclyn’s question to the pharmacist. How should the pharmacist respond to Jaclyn’s question and what counseling points are important to include?

      CONCLUSION

      Gallbladder diseases typically occur secondary to cholelithiasis. Most gallstone cases are asymptomatic, but some develop into symptomatic disease. Factors that may increase GBD risk include gender, age, family history, ethnicity, diet, and medical conditions. Surgical gallbladder removal is the most common treatment, but many nonsurgical alternatives exist when surgery is nonpreferred or contraindicated. Additionally, PCS can occur months to years after surgery and treatment should be directed based on specific diagnosis post-examination. Healthcare providers should collaborate to develop the best procedural and/or pharmaceutical treatment plan as each patient’s clinical presentation and symptoms will vary.

      The pharmacy team should take an active role in GBD management, especially following cholecystectomy. Pharmacy technicians should be weary when patients complain of abdominal pain or attempt to purchase multiple OTC products to treat their symptoms; they should relay specific disease- and drug-related questions to the pharmacist on duty. GBD is a common and highly manageable condition, and patients can live normal and healthy lives once symptoms are properly controlled and treated.

            ABSTRACT

            Recently, the US Food and Drug Administration approved an over-the-counter naloxone product. This is a welcome change that will hopefully reduce the number of opioid-related deaths in the United States, which have escalated over the last two decades. Used appropriately, naloxone can be lifesaving. In addition, its wide margin of safety contributed to the FDA's decision to move this medication from prescription status to over-the-counter (OTC) status. This continuing education (CE) activity covers important information about naloxone, signs of overdose, and naloxone use by bystanders who observe potential opioid overdoses. It also discusses the legal repercussions of using OTC naloxone. Finally, this CE covers counseling tips that are critical for laypeople who purchase OTC naloxone.

            Content

            INTRODUCTION

            The opioid epidemic has gripped the United States (U.S.) for more than two decades.1 Opioid overdose is the number one cause of death for adults aged 25 to 64 years old, which significantly contributes to the decline in the average lifespan.1 The rise of synthetic opioids (primarily fentanyl) augments the uptick in overdoses, referred to as the “3rd wave” of the opioid epidemic.1,2 In fact, 8 in 10 fatal opioid overdoses in the U.S. now involve synthetics.1 Non-fatal overdose is also significant; for every opioid-induced fatality, up to 8.4 non-fatal overdoses occur.1

             

            Prescription opioids are also a noteworthy contributor to the rise in opioid overdose deaths.2 Healthcare providers started prescribing opioids for chronic, non-cancer pain (e.g., arthritis, back pain) in the 1990s.3 In the decades since, patients started receiving increasingly higher doses of prescription opioids for long-term chronic pain management.2,3 In 2015, the amount of opioids prescribed per person was three times higher than it was in 1999.3 Even when patients take opioids as prescribed, they are still at risk of accidental overdose and drug-drug (e.g., benzodiazepines) or drug-alcohol interactions.2 Their household contacts are also at risk.

             

            Naloxone—an opioid antagonist—is the only approved treatment to reverse opioid overdose.4 The drug competes for the same receptor sites opioids use, effectively and rapidly reversing their effects (i.e., respiratory depression, sedation, and hypotension).4 Naloxone is available in intranasal, subcutaneous, and intramuscular formulations for outpatient use and intravenous formulations for inpatient use.5,6 Naloxone is a safe antidote for suspected overdose, and its use has caused the number of opioid overdose deaths to decrease in communities where it is readily available.2

             

            The U.S. Food and Drug Administration (FDA) has undertaken a series of measures to increase accessibility to this lifesaving medication.7 Until recently, naloxone was only available via prescription. In March 2023, the FDA approved the first naloxone product for over-the-counter (OTC), nonprescription use.6,7 This aims to improve access to naloxone, increase the number of locations where it is available (e.g., drug stores, convenience stores, grocery stores, the Internet), and help reduce opioid overdose deaths across the country.

             

            INCREASED ACCESSIBILITY

            The FDA first approved naloxone in 1971 as a prescription drug.6 It wasn’t until 2014 that the agency approved the first naloxone auto-injector for use outside of a healthcare setting, followed by a nasal spray formulation in 2015.8 Its status as a prescription-only medication made initial access difficult and inconsistent across the country and various high-risk groups.

             

            In the mid-1990s, community-based programs implemented efforts to increase distribution to high-risk individuals.6 Consequently, naloxone dispensing from retail pharmacies increased substantially from 2010 to 2015, with a 1170% increase between 2013 and 2015.6 Naloxone dispensing remains inadequate, however, with only one naloxone prescription dispensed for every 70 high-dose opioid prescriptions.

             

            Pharmacist Naloxone Prescribing

            It’s common knowledge that pharmacists are highly accessible, trusted healthcare professionals, so their role in naloxone distribution is not surprising. Their accessibility, medication expertise, access to patients’ medical records, and regular patient interaction are valuable tools for increasing naloxone availability.6

             

            Many states across the U.S. have enacted naloxone access laws (NALs) to expand pharmacists’ scope of practice through standing orders or collaborative practice agreements, allowing them to distribute naloxone without a patient-specific prescription.6 Studies show that NALs significantly increased naloxone prescribing, but not enough.6 Despite NALs, many pharmacists remain uncomfortable dispensing the drug without a patient-specific order given limited training, lack of understanding state laws, and lack of reimbursement for patient education. Some evidence also exists that pharmacists are afraid of potential legal ramifications.6

             

            Shifting to the Other Side of the Counter

            The FDA has a specific process for shifting from prescription to OTC approval.9 Prescription products can undergo a full switch or partial switch. A full switch converts the drug product covered under a New Drug Application (NDA) to nonprescription marketing status entirely. A partial switch only converts some of the conditions of use (e.g., indications) to nonprescription status and retains others within prescription status. A full switch requires a sponsor to submit an efficacy supplement to an approved NDA or a 505(b)(2) application, but a partial switch requires an entirely new NDA.9 Ultimately, approval of a prescription-to-OTC switch application depends on the FDA deciding that prescription status is “not necessary for the protection of the public health by reason of the drug’s toxicity or other potentiality for harmful effect, or the method of its use, or the collateral measures necessary to its use, and…the drug is safe and effective for use in self-medication as directed in proposed labeling.”9

             

            The FDA has been working to authorize an OTC version of naloxone since 2019 by prioritizing applications and assisting manufacturers pursuing OTC naloxone approval.8 The agency announced in January 2019 that preliminary assessment showed that consumers understood a model drug facts label well for OTC naloxone nasal spray and manufacturers found the label acceptable, a slow but steady step in the right direction.8 In late 2022, the FDA issued a Federal Register notice indicating that certain naloxone products—up to 4 mg nasal spray and up to 2 mg intramuscular or subcutaneous autoinjector—may be approvable for nonprescription use.10 This did not immediately approve naloxone products for safe and effective OTC use, but it did provide the framework for manufacturers to pursue approval.

             

            The FDA granted priority review status to the application to approve branded naloxone nasal spray (Narcan) for OTC use.11 It was then the subject of an advisory committee meeting in February 2023 where the committee voted unanimously to approve naloxone for nonprescription marketing.11

             

            What’s Next?

            It’s important to note that the prescription to OTC switch does not automatically apply to all forms of naloxone. Only branded Narcan 4 mg nasal spray is now granted OTC status, not its generic counterparts.7 Manufacturers of generic products with Narcan listed as their reference listed drug product will need to submit a supplemental application to switch their products to OTC status. Other brand name naloxone nasal spray products of 4 mg or less must also update labeling and apply individually for a switch to OTC status.7

             

            Pharmacy teams should also be aware that the drug will not be available on drug store shelves immediately.12 The manufacturer will need to implement manufacturing and supply chain changes to support nonprescription packaging requirements. According to the drug’s manufacturer, pharmacies can expect the OTC formulation to be available in late summer 2023. Until then, the prescription product will be readily available through current access channels.12

             

            Cost is also important to consider. The drug’s manufacturer has yet to reveal pricing plans for the OTC version, but it plans to work with public interest groups who are now charging about $47.50 per box.13 Health economists predict that the price of OTC Narcan could land somewhere between $35 and $65, plus a retailer’s markup.13 Unfortunately, this price could be prohibitive for many individuals, especially those who misuse opioids. Some also fear that this could encourage individuals to shoplift the drug, forcing locations to move the product behind the pharmacy counter or behind glass and creating a barrier to those who can afford it but are uncomfortable asking for it.13

             

            As for accessing the drug outside of a pharmacy setting (e.g., convenience stores, gas stations), additional barriers may exist. Some states require a special license for non-pharmacy businesses to sell OTC medications, which can effectively create “naloxone deserts” where the drug is not available for purchase. In the state of Connecticut, for example, 28 towns currently do not have stores with permits to sell OTC medications, causing residents to travel to obtain the lifesaving antidote.14 Pharmacy teams should check their state’s law regarding OTC sales to direct interested individuals on where to obtain the drug.

             

            NEW OPPORTUNITIES FOR THE PHARMACY TEAM

            Naloxone shift to OTC availability may seem to take the load off pharmacy teams when it comes to collaborative practice agreements and NALs, but the pharmacy team should remain heavily involved in naloxone distribution. OTC medications are often not covered by insurance, so pharmacists should stay vigilant about active NALs and collaborative practice agreements to prescribe the drug for people with cost concerns.

             

            Assessing Overdose Risk

            Prescription or not, a crucial role for pharmacy staff is identifying patients for whom naloxone is appropriate. Anyone exposed to opioids, regardless of the source, is at risk of overdose and should be considered for naloxone.15 This applies to people taking opioids for pain with or without other medications and those who misuse opioids. As the drug is bystander-administered, caregivers of individuals at risk of overdose may also request naloxone and should be educated about its use.15

             

            Paying attention to opioid dosing is important when considering patients for naloxone. A dose of 50 morphine milligram equivalents (MME) per day doubles the risk of fatal opioid overdose compared to 20 MME or less.3 Patients taking 90 MME or more daily are 10-times more likely to die from an overdose.3 Other overdose risk factors include15

            • concurrent benzodiazepine and/or alcohol use
            • history of substance use disorder, including opioid addiction
            • comorbid mental illness (e.g., depression, anxiety)
            • filling prescriptions at multiple pharmacies and/or from multiple prescribers
            • receiving a methadone prescription
            • recent emergent medical care for opioid poisoning, intoxication, or overdose
            • recent period of abstinence (e.g., release from incarceration, discharge from an opioid detox or abstinence-based program)
            • renal or hepatic dysfunction
            • comorbid respiratory conditions (e.g., smoking, chronic obstructive pulmonary disease, emphysema, asthma, sleep apnea)

             

            Counseling on Naloxone Nasal Spray Use

            The FDA deemed naloxone nasal spray safe enough for OTC use, but that doesn’t preclude the need to counsel individuals on its safe and appropriate use. Pharmacists should counsel all patients buying OTC naloxone nasal spray about signs of an opioid overdose, how to administer naloxone, and other important clinical pearls. Signs of an opioid overdose include15

            • pale and/or clammy skin
            • limp body
            • pinpoint pupils
            • blue or purple lips, nose, and/or fingernails
            • vomiting or making gurgling noises
            • unconscious or unarousable
            • breathing very slow or not at all

             

            Pharmacists should advise individuals to administer naloxone in the event of suspected overdose even if they are not 100% sure the victim is in fact suffering from an overdose.16 Administering naloxone to someone who is not actually suffering from opioid overdose is better than withholding care from an overdose victim based on uncertainty. See Sidebar: Saving a Life is Scary for additional information to ease concerns regarding naloxone administration.

             

            SIDEBAR: Saving a Life Is Scary15,17

            Often, individuals are trained and ready to perform lifesaving first-aid procedures like CPR or the Heimlich maneuver, but they are afraid of the implications if things take a turn for the worse. Naloxone administration is subject to these same liability concerns. Individuals may also be concerned about legal repercussions when calling for help at the scene of an overdose. Ensure that individuals know about supporting laws and regulations that protect them to increase comfort and confidence with administering the drug:

            • Good Samaritan*: Protects people who call for emergency medical assistance at the scene of an overdose from being arrested for drug possession.
            • Liability protection/third party administration: Protects naloxone prescribers and bystanders who administer the drug and allows bystanders to obtain naloxone for use on opioid overdose victims.

             

            *Some states have Good Samaritan laws that differ from general ones. For example, Ohio places limits on the number of times someone can be granted Good Samaritan immunity and requires that overdose victims seek referral for addiction treatment within 30 days. Pharmacy teams should stay current with state-specific Good Samaritan laws regarding naloxone.

             

            Naloxone nasal spray is available in a two-pack of single-use, prefilled devices that cannot be reused.4,5 The device should not be primed. Pharmacists should advise people buying OTC naloxone nasal spray about the following administration steps4,16:

            • Check for a suspected overdose (i.e., yell “wake up,” shake the person gently)
            • If the individual does not wake up, lay them on their back
            • Hold the nasal spray device with a thumb on the bottom of the plunger
            • Insert the nozzle into one nostril and press firmly to administer the dose
            • Call 911 immediately
            • Stay until medical assistance arrives, even if the person wakes up
            • Give another dose if the person does not wake up after 2 to 3 minutes or they become very sleepy again initial arousal
            • Continue giving doses every 2 to 3 minutes until the person wakes up or medical assistance arrives (it is safe to keep giving doses)

             

            Naloxone is a relatively safe drug, but it still comes with risks and clinical pearls that cannot be ignored. Abrupt opioid reversal in physically dependent individuals can cause acute withdrawal.4,7 Signs and symptoms include body aches, fever, sweating, runny nose, sneezing, piloerection, yawning, weakness, shivering or trembling, nervousness, restlessness or irritability, diarrhea, nausea or vomiting, abdominal cramps, increased blood pressure, and tachycardia.4 Patients may also become aggressive upon sudden reversal of opioids. Naloxone is only effective in reversing opioid overdoses, not in treating other types of overdoses, so it is crucial that individuals seek emergency medical attention following naloxone administration.

             

            CONCLUSION

            Naloxone is a vital tool for preventing fatal opioid overdose. Pharmacists should be prepared to identify people at risk of overdose and assess their need for this lifesaving drug, make all individuals aware of its OTC availability, and counsel on its safe and appropriate use.

            A. Evidence that the drug is safe for self-medication
            B. Evidence of bioavailability to the prescription product
            C. A lower dose than the prescription formulation

            2. Which of the following is an appropriate course of action following the naloxone prescription-to-OTC switch?
            A. Move all naloxone products to the customer-facing shelves of the pharmacy immediately
            B. Warn patients that naloxone nasal spray will be unavailable until late summer 2023
            C. Review state NALs and collaborative practice agreements to continue dispensing naloxone

            3. Which of the following is TRUE about naloxone nasal spray administration?
            A. Bystanders should administer a maximum of 2 doses before emergency care arrives
            B. It can cause patients to act aggressively or show signs of withdrawal
            C. Bystanders should only use it if they are 100% sure the victim used opioids

            4. It’s 2024 and your customer-facing pharmacy shelf is stocked with naloxone nasal spray. A woman presents to the counter with the product stating she knows her father is on opioids for cancer pain, but she is afraid he will accidentally take too many doses. She asks if there is anything important she should know about naloxone nasal spray and expresses that she is concerned she will not know how to identify when he is experiencing an overdose. Which of the following is the BEST counseling point for this individual?
            A. The Good Samaritan law will protect you from liability if you administer naloxone on your father and it does not work or he was not actually overdosing on opioids.
            B. If your father experiences an overdose, he will show signs of respiratory distress (slowed or stopped breathing) and be unconscious. Even if you are not 100% sure, administer the naloxone anyways.
            C. Your father is not at risk of overdose because he is using prescription opioids for cancer pain, so naloxone nasal spray is unnecessary. Use a pill organizer to ensure he uses the opioids as prescribed.

            5. Which of the following people are most likely at high risk of opioid overdose?
            A. An individual with an expired prescription for methadone who was recently released from incarceration
            B. An individual with no opioid use history who takes lorazepam (a benzodiazepine) as needed for panic attacks
            C. An individual diagnosed with gout who fills prescriptions for naproxen from both his primary care provider and an urgent care facility

            ABSTRACT

            Ulcerative colitis is an idiopathic relapsing/remitting disease that is increasing in incidence and prevalence. It is characterized by inflammation, abdominal cramping, bloody diarrhea, fatigue, and bowel urgency among other symptoms. It often presents in teens and young adults with various degrees of severity and significantly impacts quality of life. Primary treatment objectives include achieving rapid resolution of symptoms, mucosal healing, clinical and endoscopic remission, and improving a patient’s quality of life. In moderate to severe disease, prescribers employ immunosuppressive medications, anti-TNF agents, IL 12/23 antagonists, adhesion molecule inhibitors, JAK inhibitors, and S1P receptor modulators. Two organizations have published joint recommendations regarding these pharmaceuticals’ place in therapy. As more data is published and investigational therapies are approved, the treatment approach will continue to evolve. Ulcerative colitis is incurable, so some patients may require surgery. Optimizing care with a multidisciplinary team, including pharmacy personnel, remains an opportunity in this complex condition.

            INTRODUCTION

            Fiery inflammation in the bowel can be due to several conditions. In inflammatory bowel disease (IBD), gastrointestinal (GI) tract inflammation episodes are common. Crohn’s disease (CD) and ulcerative colitis (UC) are two IBDs differentiated by location and bowel involvement.1 That’s a point to remember: that IBD is an umbrella term that includes CD and UC. In 10% to 15% of patients, the features of CD and UC are so similar that it is impossible to differentiate between them and misdiagnosis may result.1,2 Besides the GI tract, both CD and UC also may be accompanied by symptoms outside the intestine, called extraintestinal symptoms.

             

            DIFFERENTIATING CD AND UC

            CD results in patchy ulceration of any portion of the GI tract (see Figure 1) from the mouth to the anus. It frequently affects the terminal ileum and colon, and bleeding is uncommon. Typically, patients experience pain in the lower right abdomen.3 UC, this continuing education’s primary focus, involves inflammation of the colon mucosa. UC often affects the rectum, referred to as proctitis, and bleeding during bowel movements is common. Typically, patients experience pain in the lower left abdomen. It may extend into the left (sigmoid) part of the pelvis or beyond the sigmoid, or include the entire colon, referred to as pancolitis.4 In UC, inflammation leads to edema, ulcers, bleeding, and electrolyte losses.

            Figure 1. The Gastrointestinal Tract

            Cartoon image showing the entire gastrointestinal tract, from mouth to anus

            UC is a chronic idiopathic relapsing/remitting condition (meaning it waxes and wanes) with interactions between the environment, immune system, gut microbiome, and a genetic predisposition to the disease suspected as causes.UC’s incidence and prevalence is increasing worldwide.6 From 1990 to 2017, its incidence increased from 3.7 million individuals to 6.8 million affected individuals worldwide.7 UC is incurable, so treatment goals aim to achieve rapid resolution of symptoms, mucosal healing, and clinical and endoscopic remission. An additional goal is to improve a patient’s quality of life (QoL).6.

             

            Individuals with this complex condition have a high level of disability and high healthcare resource utilization. Beyond medical management, 15% to 20% of patients with UC will require surgery. Compared to adults without IBD, adults with IBD experienced $11,029 higher direct costs per patient per year according to one report.8 Documenting this diagnosis in the pharmacy’s profile can help pharmacists and technicians screen for potential problems more efficiently.

             

            Differentiating the two forms of IBD drives treatment. Both CD and UC present as similar repetitive episodes of GI inflammation and create significant patient burden. In CD, inflammation or ulceration commonly occurs in the ileum and colon.4 Outside of the intestine, CD may affect the esophagus, duodenum, or stomach, and gallstones may occur. In UC, extraintestinal manifestations may appear most commonly as inflammatory arthropathies (joint disease) and bile duct inflammation and scarring, but may include bone, eye, and skin involvement.9,10 Although IBD’s incidence peaks at age 15 to 29 years, 10% to 15% of new diagnoses occur among adults aged 60 years or older.11 Both forms of IBD are more prevalent among non-Hispanic White people than among people in other racial/ethnic groups.12

            UC’S PATHOPHYSIOLOGY AND ASSESSMENT

             

            The normal colon is five or six feet long and three inches wide. Its layers of circular and longitudinal muscles and tissues contract to move food and liquid forward. It wraps around the outside of the small intestine, has segments, and looks somewhat flat. A seam runs vertically down the middle so the segments bulge on either side of the seam. As UC becomes chronic, the colon becomes more rigid and short, leading to a pipe-like appearance.9

             

            The most important risk factor for UC is a family history of IBD in a first-degree relative.14 Patients with disease extension to the left side of the colon, or extensive colitis, are more likely to need medication, undergo colectomy (removal of a portion of the colon), and develop colorectal cancer.15  Risk factors for colorectal dysplasia (abnormal that are not cancerous but can sometimes lead to cancer) or cancer include disease duration and extent, active inflammation, presence of a stricture (inelastic narrowing of a section of the GI tract), polyps, and family history of colorectal cancer. The bile duct may also become diseased in 3% to 7% of patients with UC.15,16

             

            UC’s pathophysiology involves defects in the epithelial barrier, defective immune response, the presence of leukocytes, and microflora imbalance in the colon.17,18 UC’s inflammation deteriorates the epithelium, and exposure to certain intestinal microbes worsens the inflammation.9 Other immune-related factors that affect UC’s pathophysiology and the body’s response include tumor necrosis factor-alpha (TNF-alpha), numerous interleukins, and elevated immune globulin levels.17

             

            Two measures are recognized in UC. Gastroenterologists and researchers tend to use the erythrocyte sedimentation rate (ESR) and c-reactive protein (CRP) components of the Truelove and Witts criteria. Researchers frequently measure ESR and CRP before and during treatments as outcome measures. The prescribing information for anti-TNFs, JAK inhibitors, and IL-12/23 antagonists also include ESR and CRP measures. Table 1 illustrates UC disease severity measured by assessment in the modified Truelove and Witts criteria.15

             

             Table 1. Modified Truelove and Witts Criteria15

            °C=degree Celsius; CRP = c-reactive protein; ESR = erythrocyte sedimentation rate; °F = degree Fahrenheit

             

            In the clinical setting, the simpler Mayo score (see Table 2) is used more widely than Truelove and Witts criteria.19 It reflects stool frequency, rectal bleeding, a physician’s global assessment, and a measure of mucosal inflammation at endoscopy, with a maximum score of 12. Clinical response in UC is defined as19

            • a reduction of Mayo score by at least 3 points and a decrease of 30% from the baseline score, or
            • a decrease of at least 1 point on the rectal bleeding subscale or
            • a total rectal bleeding score of 0 or 1

             

            Table 2. Mayo Score for Ulcerative Colitis15,20,19

              Points
            Mayo Variables 0 1 2 3
            Stool frequency Normal 1-2/day more than normal 3-4/day more than normal 5/day more than normal
            Rectal bleeding None Streaks of blood with stool <50% of the time Obvious blood with stool most of the time Blood passed without stool
            Mucosa (endoscopic subscore) Normal or inactive disease Mild disease (erythema, decreased vascular pattern, mild friability) Moderate disease (marked erythema, lack of vascular pattern, friability, erosions) Severe disease (spontaneous bleeding, ulcerations)
            Physician’s global assessment Normal Mild disease Moderate disease Severe disease

            Mayo score = sum of scores for each of the four variables (maximum score 12)

             

             

            Beyond clinical response, clinical remission is a desired objective and is defined as a Mayo score of 2 or less and no individual subscore exceeding 1.19 Mucosal healing is defined as a mucosa subscore of 1 or less. Disease activity is a measure used to decide what treatments to prescribe. Mild disease activity is defined as scores of 3 to 5. Moderate and severe disease activity are defined as scores between 6 and 10 and 11 and 12, respectively.19

             

            The clinician’s patient assessment must be global (all encompassing).21 During patient interviews, clinicians should inquire about extraintestinal symptoms, which may include joint, mood, ocular, oral, or skin changes. They should order laboratory evaluation for anemia and liver function abnormalities. Clinicians should explore QoL issues, such as impact on school, work, or personal relationships. Treatment plans should incorporate patients’ unmet needs and preferences. Exploring the need for social and emotional support, financial resources, and adequacy of patient education regarding their disease are important.21

             

            Throughout treatment, it’s important to assess the patient’s clinical response and remission periodically. Clinicians should monitor cross-sectional imaging, specifically MRI, CT and ultrasound, and surrogate markers, such as fecal calprotectin (FCP; type of white blood cell that migrates to inflamed tissue) and CRP.15,22 A sigmoidoscopy or colonoscopy is recommended within three to six months of initiating treatment to determine the level of suppression of the inflammation, treatment response, or the need to modify the treatment.22

             

            THE PATIENT’S JOURNEY

            The journey through symptoms, diagnosis, and treatment to quell the fiery inflammation associated with UC can be long and difficult. In one study, one in four individuals with IBD reported GI symptoms to their primary care physician more than six months before receiving a diagnosis.23 Of these individuals, 10.4% reported symptoms five years before receiving a UC diagnosis. Delayed diagnosis often results in disease progression, worsening tissue, and mucosal damage, surgery, colectomy, or colitis-associated cancer.  Patients with a previous diagnosis of irritable bowel syndrome or depression were less likely to receive a timely specialist appointment.23

             

            UC is vastly heterogeneous. Table 3 presents two cases with distinct disease journeys.

            UC affects many distinct populations. In the pediatric population with UC, unlike in adults, the clinical condition can present atypically with a more severe, early onset and continuous inflammation of the rectum and colon.26,27,28 In these patients, clinicians should assess disease location and severity. One study indicated 62% of pediatric patients with UC from birth to age 5 years had extensive pancolitis, and 38% and 31% from ages 6 to 11 and from ages 12 to 18, respectively, had pancolitis.27   Children can also experience rectal sparing (a normal/unaffected rectum) and limited distal disease.26,28

             

            To optimize management, enhance QoL, and minimize complications in all patients, continued patient engagement is important.29

             

            GOALS OF UC MANAGEMENT

             

            The UC treatment guidelines recommend goals of therapy to include29

            • induction and maintenance of clinical and endoscopic remission
            • maintaining steroid-free remission
            • improving QoL, and
            • preventing complications, hospitalizations and surgery.

            Pursuing these goals can also contribute to minimizing cancer risk.21,30,31 Long-term mucosal healing may reduce the risk of dysplasia.31

             

            The Treat-To-Target Approach                                                         

            UC is considered relapsing/remitting because it presents as relapses of symptoms and then periods of symptomless response and remission. Beyond symptom remission, a treat-to-target (T2T) approach focuses on32,33

            • minimizing disease activity
            • reducing futures risks and
            • reducing future relapses or complications such as ileal strictures (narrowing), fistulas, functional impairment, or colon cancer.

             

            In 2015, the Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) initiative recommended that UC treatment goals should address two targets: clinical and endoscopic outcomes.32 IBD experts recommend using measures of inflammation such as FCP.32  FCP detects GI inflammation sensitively and is used to monitor disease activity and predict relapse.

             

            PAUSE AND PONDER: Which UC treatments do you see in your practice location most often?

             

            UC’s treatment options are plentiful and evolving. Pharmacy team members can collaborate with multidisciplinary professionals regarding patient care for UC. (See SIDEBAR). Pharmacists’ drug therapy and disease management expertise can promote individualized treatment decisions for these complex patients.

             

             

            SIDEBAR: Working with the Multidisciplinary Team

            Team collaboration can increase patient and provider education, enhance quality of care, and reduce disease burden, and morbidity. Many pharmacists don’t know how to introduce themselves to or work with multidisciplinary teams. Sometimes, team members from other disciplines will call with questions or concerns, and the call opens the door for regular communication. Often, however, pharmacy staff will need to take the initiative and introduce themselves. Here are four tips to working better with the UC care team.

            • Ask patients if they are seeing a nutritionist, primary care provider, gastroenterologist, or behavioral health provider (for stress support). If UC is severe, inquire if they have a surgeon or know their radiologist. Record these providers’ names in the patient record and contact them when questions or concerns arise.
            • Make the patient your ally and be your patient’s ally. When you educate patients well and show them your capabilities, they will report back to their clinicians.
            • When you work with a patient who has UC, let the professional team members know. Sending a quick note to say that, for example, the patient’s adherence was poor and you discussed ways to improve it with the patient sheds light on possible non-response. It also makes clinicians aware that you have skills and you’re not afraid to use them!
            • Don’t be afraid to make team members aware of issues like cost or availability of less expensive options. Often, prescribers have no idea that patients experience sticker shock when they fill their prescriptions.

             

            TREATMENT

            Medication is a mainstay of treatment for patients with UC. Prescribers may combine, dose-escalate, reduce, or discontinue medications, depending on the patient’s disease severity.

             

            Traditional Treatments

            When a patient presents with mild to moderate UC, the expert consensus is to start treatment with an oral 5-aminosalicylate (5-ASA; sulfasalazine, mesalamine, and diazo-bonded 5-ASA [the prodrugs, balsalazide and olsalazine, which convert to mesalamine]34) with or without a rectal 5-ASA.34,35 In many cases, rectal dosing improves symptoms; using a suppository, enema, or rectal foam applies the medication exactly where needed. Sulfasalazine, balsalazide, and mesalamine are similarly effective and safe.34 Some patients will respond inadequately and may need to escalate therapy to systemic corticosteroids, immunomodulators (IMM), biologics, or other agents. If symptoms persist, it is important to rule out infection, optimize adherence, increase the oral dose, and add rectal 5-ASA if not yet prescribed.34,35

             

            Comparative efficacy studies are helpful to clinicians. One technical review of multiple drugs in mild to moderate UC compared rectal 5-ASAs (5-ASA enemas 1 to 4 g/day or 5-ASA suppositories 1g/day) to rectal corticosteroids (hydrocortisone enema 100mg/day, prednisolone enema 25–30 mg/day, budesonide enema 2 mg/day, beclomethasone 3 mg/day or comparable foam) in 13 trials.36 In mild to moderate ulcerative proctosigmoiditis cases treated for two to eight weeks, rectal 5-ASAs were superior to rectal corticosteroids for induction of clinical remission.36

             

            Table 4 lists the broad categories of medications for mild, moderate, or severe UC and dosing information.

            Sulfasalazine

            If sulfasalazine is prescribed, 4 g provides approximately 1.6 g of 5-ASA equivalence.34 Typical doses are 2 tablets 4 times a day.37,43 In some cases, prescribers may initiate therapy with a smaller dose, (e.g., 1 to 2 g daily) to reduce possible GI intolerance and slowly increase as tolerated. They may also try enteric-coated sulfsalazine.37,43 Sulfasalazine is commonly prescribed for individuals with UC and rheumatologic comorbidities.43 Periodic monitoring of complete blood counts (CBC) and liver function tests (LFT) is recommended.

             

            Sulfasalazine may be poorly tolerated due to adverse effects such as headache, nausea, diarrhea, and rash.43 Additional adverse events with sulfasalazine include folate metabolism interference, male infertility, and rare cutaneous side effects such as Stevens-Johnson syndrome. Anemia, leukopenia, or thrombocytopenia are also possible. Pneumonitis and hepatitis have been reported.43  Sulfasalazine is contraindicated if a patient has a sulfa allergy. Sulfasalazine tablets are a yellow/orange color; individuals who take it may notice an orange tinge in urine, tears, and sweat that can stain clothing and contact lenses. Auxiliary labels and counseling should emphasize drinking plenty of fluids, taking the drug on an empty stomach, and avoiding antacids.

             

            Mesalamine and Balsalazide

            Low dose mesalamine may be prescribed initially at less than 2 grams per day(g/d). Some patients need 2 to 3 g/d. Higher doses of 3 g/d or more may be required to induce remission.36 Combining oral and rectal therapy may deliver a higher effective dose of 5-ASA to the involved area and lead to higher rates of induction and maintenance of remission. This approach may avoid escalation to corticosteroids or other agents.36

             

            Mesalamine and balsalazide are associated with rare idiosyncratic worsening of colitis.22 Rare interstitial nephritis may also occur. The prescribing information recommends periodic renal function monitoring. Olsalazine is generally less well tolerated than either mesalamine or balsalazide. Headache, nausea, diarrhea, leukopenia and hepatitis are possible. 5-ASA treatments should be avoided in pregnancy.22

             

            Steroids and Other Traditional Treatments

            Corticosteroids, such as budesonide, are generally prescribed for a short duration or for induction of remission.34 Some experts suggest prescribing oral mesalamine, balsalazide or olsalazine over budesonide because hepatic first-pass metabolism lowers budesonide’s systemic activity.34,44 As the patient’s condition improves, withdrawing the steroids and reaching steroid-free remission (SFR) is important. Long-term corticosteroid use may lead to infection, diabetes mellitus, weight gain, insomnia, osteoporosis, or glaucoma.45 Mood changes, cataracts and delayed wound healing are possible.45

             

            Thiopurines and Cyclosporine

            Thiopurines, including azathioprine and 6-mercaptopurine, may improve inflammation in patients with UC. They inhibit the proliferation of lymphocytes and are used to maintain remission. Their dosing is weight-based and their onset of action can be slow, taking up to three months.22 They are often used in combination with biologics. Monitoring for drug interactions is necessary. Allopurinol interactions with thiopurines are especially important because allopurinol inhibits thiopurine metabolism.46 The dose of mercaptopurine or azathioprine may need to be reduced to one-third or one-quarter of the normal dose if allopurinol is also prescribed. Prescribers determine dose reductions based on therapeutic response and toxicity.47

             

            Even though thiopurines and cyclosporine have been prescribed for many years, remaining aware of their side effects is important. Possible adverse events of thiopurines include nausea, vomiting, fever, leukopenia, thrombocytopenia, pancreatitis, and hepatotoxicity. Rare adverse events may include non-Hodgkin lymphoma. Individuals prescribed calcineurin inhibitors, such as cyclosporine, may experience hypertension, nephrotoxicity, hyperkalemia, infection, lymphoma, or diabetes mellitus.37

             

            Additional therapies include biologics and newer small molecules (tofacitinib, ozanimod). Before discussing newer therapies, a short review of step-up and step-down approaches is reasonable. If a patient presents with moderate to severe ulcerative colitis, philosophies differ among gastroenterologists regarding beginning with a step-up versus a step-down approach.36,48

            • The step-up approach begins with the traditional therapies mentioned above and followed by biologics and IMM if symptoms persist, if remission is not achieved, and the patient is considered high-risk. Extensive inflammation and the need for repetitive use of corticosteroids are examples of high-risk status.
            • The step-down approach occurs when prescribers begin with a more intensive treatment with biologics and IMM and then step down to the medications mentioned above if patients improve.

             

            Step Up or Step Down?

            A 2021 study (N = 1891) examined UC’s clinical presentation in the five years before starting biologic therapy. The researchers analyzed patients’ experiences, comorbidities, morbidity, and treatment burden over time. Figure 2 summarizes participants’ health burden, disease progression, medication burden, and increased comorbidities. Across the study period, the need for treatment with oral corticosteroids, 5-ASA, and other non-biologic immunomodulators (IMM) increased progressively. Due to the increasing burden, the researchers supported early use of biologics (a step-down approach) rather than gradual step-up after failing conventional therapies for adult patients with moderate to severe UC.30 

            Figure showing results from the trials mentioned

            Anti-TNF agents

             

            Anti-TNF agents are commonly prescribed for moderate to severe UC due to their effectiveness, length of time on the market, and healthcare professional comfort prescribing them.44 The U.S. Food and Drug Administration (FDA) has approved many anti-TNFs, but has approved only adalimumab, golimumab, or inFLIXimab for treating UC. Usually, prescribers use anti-TNFs after 5-ASA and corticosteroids in patients with mild to moderate severity and the step-up approach to treatment. Prescribers may prescribe the step-down approach, using biologics earlier, in some cases.38 They often employ concomitant IMM to decrease immunogenicity seen with anti-TNFs.38,47

             

            Because biologics like anti-TNFs are made with living cells, patients may develop an unintended immune response (immunogenicity) in the form of anti-drug antibodies; if they develop, these antibodies may render the anti-TNF medication less effective. The antibodies may bind to the anti-TNF, interfere with its mechanism of action, reduce the anti-TNF’s serum concentration, increase its clearance, and lead to loss of effectiveness. Antibodies may also occur upon restarting an anti-TNF if a patient starts and stops an anti-TNF over time. It is unknown why some people develop anti-drug antibodies and others do not. The presence of antibodies and reduced response often prompt prescribers to switch the anti-TNF to regain effectiveness, and doing so often works. The addition of an IMM can suppress the antibodies which may reduce the risk of switching therapies or avoiding an anti-TNF dose increase.47

             

            Pharmacy team members should remain diligent about look-alike, and sound-alike names of the anti-TNF agents and should remember that doses of anti-TNF agents vary by indication.

             

            SIDEBAR: TECH TALK about Look-alike, Sound-alike medications

            Medications with names that look-alike and/or sound alike are classified as high-alert medications.

            • Know that inFLIXimab had been confused with riTUXximab, so the Institute for Safe Medication Practices recommends using TALL Man lettering.
            • Prevent medication errors between therapies for UC, such as adalimumab and golimumab, ustekinumab and upadacitinib, or vedolizumab and ustekinumab or adalimumab. Segregate the medications in different locations or consider stickers or other alert methods prior to medication dispensing.

             

             

            An Anti-integrin

            Integrins are adhesion receptors that mediate cell-to-cell and cell-to-extracellular adhesion. Vedolizumab is a humanized monoclonal antibody that binds to the α4β7 integrin, blocks the interaction of α4β7 integrin, and inhibits lymphocyte migration into inflamed GI tissue.49 With fewer lymphocytes in the GI tract, vedolizumab helps reduce inflammation and UC symptoms. Vedolizumab can be referred to as a B-anti-integrin and an adhesion molecule inhibitor. Patients with steroid-dependent disease have treatment options, including treatment with thiopurines, anti-TNF agents (may be combined with azathioprine or 6-mercaptopurine), or vedolizumab.38

             

            Prescribers and patients may ask about outcomes in clinical trials. A vedolizumab study enrolled patients with an inadequate response or intolerance to IMM therapy (i.e., azathioprine or 6-mercaptopurine) and/or an inadequate response, loss of response, or intolerance to an anti-TNF.49 Participants received IV vedolizumab 300 mg or placebo at week 0 and week 2. Concomitant stable dosages of 5-ASA, corticosteroids (prednisone dose of 30 mg/day or less or equivalent), and IMM (azathioprine or 6-mercaptopurine) were permitted through week 6. The percentage of patients achieving a clinical response at week 6 was 47%. The researchers also measured remission and found 17% of participants achieved remission at week 6. Those with a clinical response at week 6, or receiving open-label vedolizumab, were invited to enter a 52-week study with every 8-week dosing. At week 52, 42% of participants achieved clinical remission.49

             

            JAK inhibitors

             

            Tofacitinib and upadacitinib are referred to as small molecules because their molecular structure is smaller and simpler than the biologics’, which are large three-dimensional structures. The JAK inhibitors are dosed orally and require a loading dose. JAK inhibitors are indicated for adults with moderately to severely active UC who responded inadequately or couldn’t tolerate one or more anti-TNF agents.39 Many individuals are willing to visit an infusion suite for treatment; however, younger patients and those with very busy lifestyles or heavy travel schedules may prefer the small molecule oral drugs for their convenience.

             

            When prescribing JAK inhibitors, pretreatment screening should include assessment for hepatitis B and tuberculosis. When patients start biologics or JAK inhibitors, their immune response may decrease, increasing risk of certain infections, such as hepatitis B or tuberculosis. If patients have active hepatitis B or tuberculosis, they need treatment to eradicate those infections before beginning biologics or JAK inhibitors. A risk of bacterial, viral, and herpes zoster infections exists, so prescribers must assess vaccination status before treatment. CBC and lipid panel monitoring is recommended. Prescribing tofacitinib in combination with biologics for UC or with potent IMM, such as azathioprine and cyclosporine, is not recommended.40

             

             

            IL-12/23 antagonist

            Interleukin 12 (IL-12) and IL-23 are proteins that can cause inflammation. Ustekinumab is a human monoclonal antibody against the shared p40 subunit of IL-12 and IL-23 cytokines. Ustekinumab disrupts inflammation by blocking IL-12/23.41 The FDA has approved this biologic for adults with various forms of psoriasis, CD, and UC. (It is also approved for children 6 and older for various forms of psoriasis.) In UC in adults, it is typically administered as an IV induction dose, followed by subcutaneous maintenance dosing every eight or 12 weeks. Clinicians should screen for hepatitis B and tuberculosis and monitor CBC every six months.41 To minimize the risk of medication errors, pharmacy staff should double-check the prescribed route (IV or subcutaneous). They should also be alert for look-alike, sound-alike issues, to prevent prescription transcribing errors or other confusion between ustekinumab and the JAK inhibitor upadacitinib.

             

            Research has documented outcomes for this monoclonal antibody, too. A ustekinumab clinical trial assessed efficacy and safety in adults with UC; the primary endpoint was clinical remission at week 8.41 The researchers randomized participants to a single IV dose of ustekinumab of approximately 6 mg/kg, 130 mg (a lower dose than recommended), or placebo at week 0. Enrollment required previous inadequate response to corticosteroids, IMM, or at least one biologic. At week 8, 19% of participants successfully reached clinical remission.41

             

            S1P Modulator

            Ozanimod is an oral sphingosine 1-phosphate receptor (S1P) modulator indicated for the treatment of moderately to severely active UC in adults.42 It is also approved for relapsing forms of multiple sclerosis, and the pharmacy team may field questions about this medication’s various indications. Ozanimod binds with high affinity to S1P receptors 1 and 5. It blocks lymphocyte trafficking from lymph nodes, reducing the number of lymphocytes in peripheral blood. Ozanimod may transiently decrease heart rate and cause atrioventricular conduction delays, so a low-dose starter titration pack is available. Prescribers should escalate the dosing slowly to avoid rare but significant bradycardia. Progressive multifocal leukoencephalopathy, a disabling, sometimes deadly adverse event, is rare but possible. Pharmacy teams should counsel patients regarding the need for effective contraception to prevent pregnancy; patients should use contraceptives for three months after discontinuing ozanimod.42

             

            An ozanimod clinical trial assessed efficacy and safety using a primary study endpoint of clinical remission at week 10.42 It enrolled adults with moderately to severely active UC if they had an inadequate response, or were intolerant, to specific other treatments. The treatments included oral 5-ASA, corticosteroids, IMM (e.g., 6-mercaptopurine and azathioprine), or a biologic (e.g., anti-TNF and/or vedolizumab). The proportion of patients reaching clinical remission at week 10 was 18% with an ozanimod dose of  0.92 mg once daily. Those achieving a clinical response were invited to be re-randomized to a 52-week study extension. The primary endpoint was the proportion of patients in clinical remission at week 52. The proportion of patients with an ozanimod dose of 0.92 mg once daily with clinical remission at week 52 was 37%.42

             

            MEDICATIONS IN DEVELOPMENT

            Etrasimod is a once-daily, oral S1P receptor modulator in development for the treatment of UC. Results from the phase 2 OASIS trial and open-label extension study revealed patients with moderately to severely active UC who received etrasimod showed improvements in clinical remission and symptom relief beginning as early as week 2. In the phase 3 ELEVATE UC 52 study, 27% of patients in the etrasimod group achieved clinical remission compared with 7% of patients in the placebo group at 12 weeks.50 Use of etrasimod in UC is not FDA-approved and regulatory authorities have not yet evaluated its safety and efficacy.

             

            Risankizumab-rzaa is an IL-23 inhibitor that is FDA-approved for psoriasis and Crohn’s disease. It is in development for treatment of individuals with UC. In the INSPIRE trial, 20.3% of participants with intolerance or inadequate response to conventional or advanced therapies (biologics, JAK inhibitors, and S1P receptor modulators) achieved clinical remission at week 12.51 The FDA has not approved risankizumab in UC or evaluated its safety and efficacy.

             

            Considerations for Medications in Therapy

            Decision-making regarding UC treatment requires consideration of many factors, including

            • disease and inflammation location, severity, and extent
            • comparative effectiveness and long-term safety of available treatments
            • treatment availability
            • product labeling
            • guideline recommendation
            • prior treatment successes or failures
            • cost, and
            • patient preferences

            Since some prescribers may dose escalate to an off-label (higher) dose or off-label shorter dosing interval, pharmacy teams need to remain alert regarding insurance policies that may impact treatment decisions.

             

            Safety Information

            Each medication’s full prescribing information includes comprehensive safety and efficacy details. The information in this section is not all-inclusive. It’s critical to keep in mind that all UC treatments have limitations. Because most infusions have similar adverse events, Table 5 summarizes select safety information and limitations regarding newer agents used in UC.

            Identifying drug interactions is a key skill for pharmacists. Of note, JAK inhibitors can interact with CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin) and CYP2C19 inhibitors (e.g., fluconazole, omeprazole).40 Drug interactions may be a concern with the use of ozanimod and concurrent IMM, tyramine, antiarrhythmics, beta blockers, or calcium channel blockers.42

             

            ACG and AGA Guidelines for the Management of Moderate-to-Severe UC

            The American College of Gastroenterology (ACG) and the American Gastroenterological Association (AGA) published comprehensive treatment guidelines and interventions for UC.31,44 Both guidelines cover achieving a response, induction of remission, and maintenance of remission. Select highlights presented below are not all-inclusive.

             

            For remission induction, ACG recommends the following options31:

            • In moderately active UC, oral budesonide MMX
            • In moderately to severely active UC, oral corticosteroids
            • In moderately to severely active UC, anti-TNF therapy
            • When inFLIXimab is used as induction therapy for patients with moderately to severely active UC, it should include a thiopurine
            • In moderately to severely active UC, or if failed anti-TNF, vedolizumab
            • In moderately to severely active UC, tofacitinib 10 mg orally twice a day for 8 weeks
            • For induction of remission in moderately to severely active UC with previous failure of anti-TNF therapy, tofacitinib

             

            For maintenance of remission, ACG recommends the following options31:

            • For previously moderately to severely active UC in remission due to corticosteroid induction, thiopurines
            • Continue anti-TNF therapy after anti-TNF induction in patients with previously moderately to severely active UC
            • Continue vedolizumab in previously moderately to severely active UC now in remission after vedolizumab induction
            • Continue tofacitinib in previously moderately to severely active UC now in remission after induction with tofacitinib

             

            The AGA provides the following recommendations for response and remission44:

            • Current evidence supports use of inFLIXimab, adalimumab, golimumab, vedolizumab, and tofacitinib for remission induction and maintenance in moderate-severe UC
            • Thiopurine monotherapy should not be used for induction of remission but may be considered for remission maintenance
            • Meta-analysis suggests that inFLIXimab and vedolizumab may be preferred first-line therapy in biologic-naïve patients, rather than standard-dose adalimumab or golimumab
            • In patients with prior inFLIXimab exposure, particularly those with primary non-response to induction therapy, vedolizumab or tofacitinib may be preferred over adalimumab or golimumab
            • Combination of a biologic agent with an immunomodulator is more effective than monotherapy with either agent
            • In patients with moderate-severe disease activity, at high risk of colectomy, biologic agents with or without an IMM, or tofacitinib, should be used early rather than gradual step-up therapy after failure of 5-ASA
            • Patients in remission with biologic agents and/or IMM, or tofacitinib, after prior failure of 5-ASA, may discontinue 5-ASA

            Patient Education Pearls for Patient Counseling

             

            Pharmacy teams have numerous opportunities to provide UC patient education. Because the condition appears differently in affected individuals, conversations should align with the individual patient’s situation. Supportive patient education pearls addressing inflammation and advancing opportunities to remission should be individualized from these topics53:

            • UC’s exact cause is unknown
            • UC affects people differs widely
            • UC is a chronic condition and symptoms wax and wane
            • Medications are available to control UC
            • The number of people with UC has been increasing
            • It can occur at any age and in any racial or ethnic group
            • Symptoms will occur in the intestine and may occur outside of the intestine
            • Ulcers in the intestine lining that bleed may lead to low red blood cell count (anemia)
            • Ask the doctor what tests are needed
            • Diet and nutrition plans differ for each patient
            • Managing stress is important
            • Have supportive friends and family
            • Locate restrooms when outside the home
            • Carry extra underclothes, toilet paper or moist wipes
            • Ask for school or work accommodations

             

            SIDEBAR: OTC and Alternative Therapies for Patient Discussion34,35,44,54

             

            Patients with UC may use these OTC products:

            • Patients with UC may eat less, thinking it will decrease diarrhea. However, they need proteins, water, vitamins, and minerals to promote healing. Patients need vitamin D and calcium for bones if reduce their dairy intake.
            • Bismuth subsalicylate (Pepto Bismol) is an antidiarrheal liquid, chewable tablet, and also swallowable tablet. It helps reduce inflammation in the intestinal lining. Remind patients that it darkens stool and the tongue. That darkening is not a medical concern.
            • Simethicone (Gas-X) is an anti-flatulent that helps form gas bubbles in the digestive tract, making them easier to pass and relieving gas pain.
            • Loperamide (Imodium) should be taken with caution. It slows digestion. Occasional use may be effective, but patients should consult healthcare providers if they contemplate ongoing use.
            • If mild disease persists, such as seen with a Mayo score of 1, the AGA guidelines and some advocacy web sites mention curcumin (a phytochemical from turmeric) or suggest adding curcumin and probiotics for some individuals suffering with UC.
            • Patients with severe disease, frequent bleeding, anemia, or abnormal laboratory results may need folic acid. The usual folic acid dose is 1 mg/day. Asparagus, broccoli, and spinach are also foods that contain folate or folic acid.

            Patients who have UC should avoid these OTC products:

            • Patients should consult their healthcare providers whether to avoid aspirin, nonsteroidal anti-flammatories (ibuprofen, naproxen), lactose, sugar substitutes, or preservatives.
            • Patients who take sulfasalazine or mesalamine should not take them with antacids.

             

            Many institutions, hospitals and healthcare providers have created UC resources. Table 6 lists  examples of supportive options that can be shared with individuals with UC.

            CONCLUSION

            UC is a debilitating chronic IBD that usually requires long-term treatment to control symptoms and prevent disease-related complications. Many treatments are available; however, the effectiveness, safety, and durability of response and remission vary, and careful assessment of these factors must drive a personalized approach to care. Pharmacy teams must recognize that every patient’s disease is different, and results in diverse manifestations. Pharmacists and pharmacy technicians are ideally positioned to collaborate with multidisciplinary teams to support strategies tailored to each patient to optimize care and to help patients maintain a positive outlook.

             

            Many unanswered questions remain about UC. Researchers will continue to evaluate treatment advances and explore disease management opportunities while pharmacy teams encourage patients suffering from UC to have routine doctor visits, adhere to their medication regimen, and maintain a healthy lifestyle.
