182 - 2023 Beers Criteria Update: Navigating Medications Safely in Older Patients
In this episode, we discuss principles for medication use in the geriatric patient population and summarize the updated 2023 American Geriatrics Society Beers Criteria for Potentially Inappropriate Medication Use in Older Adults. Key Concepts The Beer’s Criteria was originally developed by Dr. Mark Beers in 1991 to identify medications in which the risks may outweigh the benefits in nursing home patients. This list is now maintained by the American Geriatrics Society and includes a variety of drug safety information related to elderly patients including medications that are considered potentially inappropriate (Table 2 and 3), medications used with caution (Table 4), drug-drug interactions (Table 5), drugs with renal dose adjustments (Table 6), and drugs with anticholinergic properties (Table 7). The newest update prefers apixaban over other DOACs for VTE and atrial fibrillation in elderly patients. This is a very controversial recommendation given that other guidelines (e.g. from the ACC/AHA) have not published a similar preference of one DOAC over another. Many of the medications that are potentially inappropriate involve drugs that have anticholinergic properties and drugs that increase the risk of incoordination and falls. Other resources exist to guide drug therapy decisions in elderly patients. As an example, the STOPP/START criteria (published in the European Geriatric Medicine journal) outlines drugs to avoid but also drugs to consider in elderly patients.

181 - From Meds to Machine Learning: How AI is (and will) Revolutionizing Pharmacy Practice
In this episode, we discuss artificial intelligence large language models (LLMs) and how these will impact the future of the practice of pharmacy. Key Concepts Generative AI with large language models (LLMs) have already changed how healthcare is delivered to patients. In the future, these changes will be more substantial and require pharmacists and other healthcare professionals to understand the benefits and downsides of this technology. Commercial LLMs, such as ChatGPT, are not HIPAA compliant and should not be used with protected health information. Companies currently offer software products that are HIPAA compliant and can integrate directly into electronic health records in a HIPAA-compliant manner. Currently, most commercial use cases of LLMs for healthcare providers focus on expediting or simplifying the documentation process (e.g. generating a first draft of a progress note or summarizing a patient encounter from an audio recording). In the future, LLMs will be used to perform a variety of clinical tasks, including drug interaction checking, renal dose adjustments, duplication of therapy, and even the appropriateness of a patient’s drug regimen for a given medical condition. These clinical tasks will almost certainly be done as a “first pass” to highlight or flag specific aspects of a patient’s chart and will then be reviewed by a licensed (human) healthcare provider as a final check prior to clinical decisions being made.

180 - The Ultimate Guide to Statins: An In-Depth Drug Class Review
In this episode, we review the pharmacology, indications, adverse effects, monitoring, and unique drug characteristics of HMG CoA reductase inhibitors (“statins”). Key Concepts Statins reduce LDL cholesterol by 20-60% (depending on the dose and statin potency). They have modest favorable effects on HDL and triglycerides. Clinically, statins reduce the risk of major adverse cardiac events by about 30% depending on the statin potency. There are four main groups of patients who are indicated for a statin: LDL >= 190 mg/dL, diabetes with age 40-75 years with LDL 70-189 mg/dL, those with an elevated 10-year ASCVD risk of > 7.5% (or possibly > 5%), and those who have had an ASCVD event (“secondary prevention”). Atorvastatin, lovastatin, and simvastatin heavily rely on CYP 3A4 metabolism and tend to be most susceptible to drug interactions compared to the other statins. When a statin is started, baseline lipid panel and liver function tests should be obtained. After 4-12 weeks, a lipid panel should be repeated. Liver function and creatine kinase testing should only be done if a patient has a symptom (e.g. jaundice, right upper quadrant pain, muscle pain or weakness, dark urine, etc.) References Grundy SM, Stone NJ, Bailey AL, et al. 2018 AHA/ACC/AACVPR/AAPA/ABC/ACPM/ADA/AGS/APhA/ASPC/NLA/PCNA Guideline on the Management of Blood Cholesterol: A Report of the American College of Cardiology/American Heart Association Task Force on Clinical Practice Guidelines.

179 - Annual Dose of Sweetness: 2024 Updates from the American Diabetes Association Guidelines
In this recurring episode, we discuss the important updates from the 2024 American Diabetes Association Guidelines! Key Concepts Tirzepatide is now recommended as one of the weight loss pharmacotherapy options along with semaglutide in patients with diabetes. The language for its use in comparison to insulin therapy has been updated similar to GLP-1RAs. The new hypoglycemia section in chapter 6 now houses all recommendations regarding screening, education, prevention, and treatment of hypoglycemia. The recommendation for prescribing glucagon has been clarified - regardless of type of diabetes, it is recommended that glucagon be prescribed to all patients using insulin or those who are at high risk with proper education of family members or caregivers. Teplizumab, a monoclonal antibody against CD30, is available for preventing progression of stage 2 type 1 diabetes to stage 3 type 1 diabetes. Guidelines have updated screening criteria for staging type 1 diabetes and recommends use of teplizumab in these patients. Other updates revolve around emphasis of using diabetes technology such as CGMs and AID for appropriate patients, clarified or strengthened screening recommendations for type 1 staging, peripheral arterial disease, bone mass density, etc., and emphasis on weight management alongside meeting glycemic goals.

178 - Law & Order: Pharmacy Edition. A Concise Review of High-Yield Pharmacy Law Topics for the MPJE
In this episode, we speak with Janeen Winnike, the Associate Dean for Student Affairs at Rosalind Franklin and a co-course director for the Pharmacy Law course at the university. We review some of the key points regarding federal and Illinois pharmacy law – a must-listen especially for graduates preparing for their MPJE exam after graduation! Key Concepts The FDA (via the Food, Drug, and Cosmetic Act) primarily regulates manufacturers. Most regulation for pharmacies and pharmacists is via the federal Controlled Substances Act and state-based regulations (acts and administrative codes). An IND (investigational drug application) is required to begin human clinical trials (phase I-III). An NDA (new drug application) is used for the FDA to consider whether a drug should be approved for use in the US. The Federal Controlled Substances Act outlines which drugs are scheduled I-V. State law can be more restrictive. C-II drugs have special regulations related to prescribing, ordering/distribution, refills, partial fills, etc. In Illinois, pharmacists, student pharmacists, and pharmacy technicians are permitted to vaccinate patients aged 7 years and older (or temporarily 3 years and older per the PREP act for COVID-19 and influenza vaccines). Pharmacists can order and administer COVID-19 and influenza vaccines; other vaccines require a standing order or a prescription in order prior to administration in a pharmacy.

177 - The Antidote Arsenal: Exploring the Emergency Toolbox for Anticoagulant Reversals
In this episode, we review evidence-based guidelines for the emergency reversal of warfarin, dabigatran, and the oral Xa inhibitors (apixaban, edoxaban, and rivaroxaban). Key Concepts Reversal of anticoagulation is indicated in patients with major hemorrhage or when emergency surgery is necessary. Reversal of warfarin (Coumadin®) involves a fast-acting, short-term solution (usually prothrombin complex concentrates [PCC]) and a slower-acting, long-term solution (intravenous vitamin K). Idarucizumab (Praxbind®) is the preferred reversal strategy for dabigatran (Pradaxa®). Idarucizumab is a monoclonal antibody fragment specific that binds and inactivates dabigatran. If idarucizumab is unavailable, PCCs are recommended. Andexanet alfa (Andexxa®) is the preferred reversal strategy for oral Xa inhibitors and has FDA approval specific to apixaban and rivaroxaban. Andexanet alfa is a decoy factor Xa protein with higher binding affinity than human clotting factor Xa. There are several barriers to use with andexanet alfa that has led to low utilization in hospitals. If andexanet alfa is unavailable, PCCs are recommended. References Baugh CW, et al.

176 - Hormonal Harmony: A Pharmacist’s Guide to Hormonal Contraceptives (Part 2)
In this two part episode, we review some of the most important clinical pearls in the pharmacotherapy and practice aspects of hormonal contraceptives with a brief focus on the very first FDA approved OTC hormonal contraceptive product (Opill). Key Concepts (Part 2) Missed dose instructions are particularly important with progestin only pills (POPs). Patients should take POPs at the same time (within 3 hours) each day - missing a dose beyond this 3 hour window is considered a missed dose and requires barrier contraception. There are a wide variety of hormonal contraception options for patients - each with its own unique advantages and disadvantages. Shared decision making between a healthcare provider and a patient is critical to selecting the most appropriate form of contraception! The CDC's Medical Eligibility Criteria (MEC) is an important resource to guide prescribers with regards to selecting hormonal contraception and also in identifying the clinical significance of a variety of drug interactions with hormonal contraception. One of the most important aspects of hormonal conctraception is adequate patient follow-up. Especially given the wide variety of hormonal contraception options, patients may need to switch their contraceptive multiple times until they find one that works best for them. Close follow-up and patient counseling are pivotal for helping a patient identify their optimal regimen. References CDC Selected Practice Recommendations for Contraceptive Use. 2016.

175 - Hormonal Harmony: A Pharmacist’s Guide to Hormonal Contraceptives (Part 1)
In this two part episode, we review some of the most important clinical pearls in the pharmacotherapy and practice aspects of hormonal contraceptives with a brief focus on the very first FDA approved OTC hormonal contraceptive product (Opill). Key Concepts (Part 1) The effectiveness of contraceptives varies based on “ideal use” (e.g. in a clinical trial with optimal compliance) versus “typical use” (e.g. real-world effectiveness in patients who may sometimes be less adherent than in clinical trials). Oral, patch, and ring-based hormonal contraceptives (combination estrogen-progestin or progestin-only formulations) with “typical” use are about ~90% effective, meaning in one year there are ~10 unplanned pregnancies with these contraceptive options. When using an estrogen-based oral contraceptive, the estrogen dose should be initiated at a low dose (25 mcg or less per day of ethinyl estradiol). The dose of estrogen may need to be increased if breakthrough bleeding occurs in the early/mid cycle despite being on therapy for at least 6 months. Breakthrough bleeding later in the cycle is typically due to an inadequate progestin dose. In general, manufacturers do not provide multiple different formulations with different progestin doses; therefore, if late breakthrough does occur, an alternative formulation with a different progestin should be considered. If a patient misses one dose of a combination oral contraceptive, they should take the missed dose as soon as possible (even taking two doses at once if they remember when the next dose is due). If two or more doses are missed, the package insert should be consulted for instructions – management depends on the timing of the cycle, recency of unprotected sex, and other factors.

174 - Finding Your Mount Rushmore: The Journey of an Industry Pharmacist
In this episode, we interview Scott Glosner, PharmD, MPH, BCPS about his extensive experience working at Pfizer in medical outcomes and as a field medical director. Dr. Glosner will share his career journey from a clinical pharmacist transitioning into the pharmaceutical industry in the late 1990s and what current pharmacists and students should know about a job in a pharmaceutical company. Key Concepts Pharmacists are playing an increasingly important role within the pharmaceutical industry. Prior clinical experience is a significant advantage to applicants for these positions. Key characteristics of a competitive pharmacist applicant for an industry position include strong communication skills, being perseverant (“tough skin”), being extremely persistent, and having real-world clinical experience. Different companies and job positions within industry often require differing amounts of prior experience. Applicants with more than several years of experience (or equivalent fellowship experience) may be more competitive for positions. Standing out in any way, whether board certification, doing research, networking, etc. is important for any applicant. In the future, pharmacists in industry may be playing a greater role in the oncology space, social determinants of health, emerging topics (such as gene therapy), and being capable of analyzing and interpreting “real world” clinical trial data.

173 - Balancing Access and Safety: The FDA's Prescription Drug Risk Mitigation Strategy (REMS)
In this episode, we will discuss the definition of REMS (Risk Evaluation and Mitigation Strategies), why they exist, the role of FDA in administering REMS, types and examples of REMS, and how they impact pharmacy practice. Key Concepts The REMS (Risk Evaluation and Mitigation Strategies) program was developed in 2007 as part of the FDA’s drug risk management strategies designed to balance risk and benefits of certain drugs. Elements of REMS vary depending on the drug, but commonly include medication guides, communication plans, and other elements to assure safe use. REMS can require patients, providers, and pharmacies to take certain actions including training, registration, enrollment, safety monitoring, documentation of safety concerns, and follow prescribing and dispensing regulations. The FDA captures and assesses data on a regular basis to make changes in the REMS program. It also has authority to enforce compliance and take punitive actions against non-compliant parties.

172 - Battle of the Clot Busters: Alteplase vs. Tenecteplase for Acute Ischemic Stroke
In this episode, we review the role and indications of thrombolytics in acute ischemic stroke. The efficacy, safety, administration considerations, and cost between alteplase and tenecteplase are compared and contrasted. Key Concepts Alteplase (Activase) is a recombinant DNA version of human TPA (tissue plasminogen activator). Tenecteplase (TNKase) is similar to human TPA except it has three amino acid changes that result in a longer half-life and higher fibrin specificity. In patients with stroke, alteplase is given as a bolus followed by a 60-minute infusion. Tenecteplase is given as an IV bolus without the need for an infusion due to its longer half-life. Tenecteplase is at least as safe and effective as alteplase in acute ischemic stroke (with some studies showing greater benefit with tenecteplase). In patients with acute ischemic stroke who are candidates for mechanical thrombectomy, thrombolytics (with alteplase or tenecteplase) will still be given in patients who meet inclusion criteria and have no exclusion criteria.

171 - Two Vax’s and a MAB: What’s New in RSV Prevention
In this episode, we briefly review RSV (respiratory syncytial virus) infections and focus on new data supporting the use of two different RSV vaccines (Abrysvo and Arvexy) in preventing RSV infections in older adults and in pregnant women. Key Concepts RSV is a contagious respiratory virus that is usually mild and self-limiting in most patients but can cause severe disease especially in young children or older adults with certain risk factors. The FDA recently approved two vaccines for RSV (Abrysvo from Pfizer and Arexvy from GSK). The initial FDA approval was for adults 60 years of age and older; however, the FDA recently granted an additional indication for Abrysvo for pregnant women (to prevent the infant from severe RSV infection once born). When studied in older adults, both vaccines did meet efficacy criteria but the incidence of RSV infection was relatively low and thus the number needed to treat (NNT) is high. Both studies were done at times with lower RSV prevalence - the NNT would likely be more favorable during RSV outbreaks. Unlike Abrysvo, Arvexy (GSK) contains an adjuvant to improve the immune response. Although direct comparisons of efficacy and safety are not appropriate, Arvexy does appear to elicit more systemic adverse effects such as fever, myalgias, headache, and fatigue.

170 - Hope and Healing: Overcoming Opioid Use Disorder Through Evidence-Based Therapies
In this episode, together with our faculty colleague, Dr. Roberta Dume, PharmD, BCPP, we discuss the pharmacologic options and evidence for the treatment of opioid use disorder (OUD) and how pharmacists play a vital role in assisting patients suffering from opioid use disorder. Key Concepts The treatment for OUD should be provided by either the treating clinician or a certified Opioid Treatment Provider (OTP) using one of three FDA-approved therapies which include buprenorphine, methadone, and naltrexone. Selection of the OUD treatment depends on availability of treatment provider; pharmacologic agent specific factors such as efficacy, dose titration, safety, and need for detoxification; and patient factors such as ability to safe-keep medications, adherence to required clinic visits, or presence of comorbidities. Pharmacists can play an important role for patients needing OUD by providing treatment education, treatment induction, monitoring treatment outcomes, harm reduction by providing naloxone and related education, and utilizing preventative strategies such as monitoring opioid use, offering non-opioid pain management options, and promoting safe storage and disposal of opioids.

169 - Introducing HelixTalk’s 2023 Drug Superlative Awards!
In this episode, we announce the second iteration of the HelixTalk Drug Superlative Awards -- awards given to medications on the market that are outstanding or notorious. In announcing these completely fictitious awards, we review key clinical pearls and pitfalls that every clinician should be aware of with these notable medications. Key Concepts The award for the most unique phase III patient population for a widely used medication goes to … Pneumovax-23 (PPSV-23) for its predecessor versions that were studied in South African novice gold miners. The award for the most misunderstood boxed warning goes to … all of the DOACs (but specifically apixaban and rivaroxaban). In particular, due to BOTH an increased risk of thrombosis and bleeding when switching from a DOAC to warfarin therapy in patients with atrial fibrillation. The award for the biggest difference between pharmacokinetic properties and pharmacodynamic effects goes to … aspirin due to its short-half life and short duration of analgesic effect and yet very prolonged antiplatelet effect. The award for the drug that should be dispensed with extra toilet paper … TIE between irinotecan and clindamycin. The most common dose-limiting adverse effect of irinotecan is diarrhea – loperamide is extensively used in these patients. Clindamycin earns the award because it is the antibiotic most associated with Clostridium difficile-associated diarrhea (CDAD).

168 - Beyond the Controversy: Exploring Efficacy and Safety of Medication Abortion
There has been a lot of news about abortion (abortifacient) medications recently. Since the overturn of Roe v. Wade in 2022, individual states passed their own laws restricting access to abortion, this includes access to abortion medications. This clearly impacts the way pharmacists practice. In this episode, we summarize the science behind the two main abortive drugs, mifepristone and misoprostol, and provide a picture of how the access to these medications stand in the United States. Key Concepts Among other modalities to terminate pregnancies, medication abortion is a safe and alternative option that is picking up popularity given recent changes post-Dobbs vs. Jackson WHO decision. The FDA-approved use of combination mifepristone and misoprostol regimen to terminate pregnancy up to 70 days (10 weeks of gestation) is based on strong evidence for its efficacy and safety. Since the overturning of Roe vs. Wade in 2022, states have taken their own action to further restrict or increase access to abortion services including access to medication abortion. These legal changes further impact dispensing of mifepristone and misoprostol by pharmacists across the country adding to more confusion. Legal councils, state boards of pharmacies, or state pharmacy associations may serve as suitable resources to consult regarding these fast-changing laws.

167 - Beyond One-Size-Fits-All: Unraveling the Genetic Tapestry of CYP2D6 Drug Metabolism
In this episode, we review the science behind genetic differences in humans in the CYP2D6 hepatic enzyme responsible for drug metabolism and how these genetic variants can lead to certain drugs being metabolized far too much or far too little, which can cause drug toxicities or a lack of effectiveness. Key Concepts About 20-25% of drugs on the market are metabolized by CYP2D6. Humans have a huge degree of variability in CYP2D6 metabolism ranging from “ultra” metabolizers to “poor” metabolizers. Drugs that heavily rely on CYP2D6 metabolism are prone to large variability in responses due to these genetic differences. Some drugs rely on metabolic inactivation of CYP2D6 whereas other drugs use the enzyme to become converted to a more active compound. Codeine and tramadol both heavily rely on CYP2D6 activation to a more potent opioid compound. Patients with excessive CYP2D6 activity will have toxicities (from too much of an active metabolite) whereas patients with low CYP2D6 activity will have little therapeutic effect. Numerous antidepressants (paroxetine, nearly all tricyclic antidepressants, and venlafaxine) rely on CYP2D6 metabolism. Differences in CYP2D6 metabolism have been shown to either cause toxicity or a lack of effectiveness with these medications. References Chartrand R, Forte AM, Hoger JD, Kane SP, Kisor DF.

166 - Thiazide Throwdown: Hydrochlorothiazide vs. Chlorthalidone - The Ultimate Showdown for Hypertension Management
In this episode, we compare hydrochlorothiazide and chlorthalidone, but specifically from a cardiovascular outcomes perspective when used in patients with hypertension. Key Concepts Chlorthalidone, hydrochlorothiazide, and indapamide are available thiazide diuretics for treatment of hypertension; however, hydrochlorothiazide is the most commonly used agent. Chlorthalidone is more potent in reducing blood pressure but also is associated with a higher risk of electrolyte abnormalities compared to HCTZ. Recent studies for cardiovascular outcomes show that chlorthalidone is not better than HCTZ in preventing CV outcomes, but increases risk for hypokalemia, need for monitoring and even potassium supplementation.

165 - QT and the Beast: Managing Medications That Prolong the QT Interval
In this episode, we discuss the concerns of QTc prolongation, which can cause a fatal arrhythmia called torsades de pointes (TdP). We cover the difference between QT and QTc, how to interpret a QTc (and when it is inaccurate), common medications that prolong QTc, and how pharmacists can evaluate the risk of QTc/TdP in patients who are receiving QTc-prolonging therapies. Key Concepts The QTc interval is the QT interval that has been “corrected” for heart rate. In nearly all cases, when describing a QT interval, it should be expressed as the QTc. Although a prolonged QTc is usually defined as a QTc exceeding 450-480 msec, the risk of torsades de pointes (TdP) begins to become concerning when the QTc is more than 500 msec, 15-20% longer than baseline, or if the QTc has increased by more than 60 msec. Vaughan-Williams Class III antiarrhythmics are most implicated in QTc prolongation and TdP risk. These therapies include sotalol, dofetilide, and dronedarone. Although amiodarone is a class III antiarrhythmic, its risk of TdP is quite low despite the fact that it often substantially prolongs the QTc. When pharmacists are assessing the risk of QTc prolongation and TdP, multiple factors (not just the QTc itself) should be considered. Risk scores, like the Tisdale Risk Score, as well as considering the risks/benefits of switching drug therapy, should be evaluated. References CredibleMeds.com.

164 - Breaking Down the Updates: Key Changes and Implications of the 2023 American Diabetes Association Guidelines
In this episode, we will discuss the most important updates from the American Diabetes Association’s 2023 Standards of Care in Diabetes. Key Concepts The first-line therapy for type II diabetes is based on whether the primary goal of therapy is cardiorenal benefit (reduced risk of ASCVD, heart failure, or CKD) or glycemic and weight goals. For cardiorenal benefit, GLP1 receptor agonists and SGLT2 inhibitors are heavily emphasized. For glycemic control and weight gain, GLP1 receptor agonists (or GLP1/GIP in the case of tirzepatide) have a very favorable effect on weight loss and glycemic control. While metformin is still mentioned, it is no longer the sole, first-line therapy for type II diabetes. For patients with diabetes and a high risk of ASCVD (20% or higher), high-intensity statins, ezetimibe, and/or PCSK9 inhibitors are recommended to achieve an LDL less than 70 mg/dL. In patients with a history of ASCVD events, these same therapies are used to achieve a recommended LDL goal of less than 55 mg/dL. Among selected patients with diabetes and CKD with albuminuria, finerenone (a new mineralocorticoid receptor antagonist) is recommended to improve renal and cardiovascular outcomes. A variety of different therapies are now recommended for neuropathic pain, including gabapentinoids, SNRIs, TCAs, and several antiseizure medications (lamotrigine, lacosamide, oxcarbazepine, and valproic acid). A wide variety of other new recommendations are discussed in the episode, including NASH/NAFLD, obesity and weight management, special populations, diabetes technology, and health behavior changes.

163 - The Two-Drug Tango: A Concise Guide to Tacrolimus and Mycophenolate in Organ Transplantation
In this episode, we review clinical pearls and common pitfalls of immunosuppression regimens for organ transplantation with a particular focus on tacrolimus and mycophenolate. Key Concepts Most recipients of an organ transplantation will be on a two or three drug regimen. The most common regimen is tacrolimus and mycophenolate with/without a corticosteroid. Tacrolimus is hepatically eliminated and susceptible to CYP3A4 and PGP drug interactions. Particularly at higher drug concentrations, it is associated with nephrotoxicity and neurotoxicity (among several other adverse effects). Mycophenolate is unstable in the acidic environment of the stomach. The two formulations on the market are CellCept (which uses a prodrug, mycophenolate mofetil, that is converted in the liver to an active compound) and Myfortic (an enteric-coated formulation of mycophenolic acid, which releases after exiting the stomach). The intensity of an immunosuppression regimen is determined by numerous factors, including the type of organ, how long ago the organ was transplanted, if acute rejection has occurred in the past, patient-specific risk factors, and more.

162 - A1C You Later: A Concise Review of Continuous Glucose Monitors for the Practicing Pharmacist
In this first ever CE episode, we discuss the A-Zs of continuous glucose monitors (CGMs). In specific, our learning objective for the CE are: Describe commonly available types of continuous glucose monitors (CGMs) in the US market and the features and capabilities of these devices. Summarize the evidence and guideline recommendations for use of CGMs in the management of diabetes. Identify the role of the pharmacist in the selection of CGMs and provision of education to patients and providers. Interpret the ambulatory glucose profile (CGM data output) and recommend changes in antihyperglycemic regimen for a patient.

Once payment is successful, you will be redirected to our CE partner (CE Impact) to complete an evaluation and to earn 1.0 hour of CE credit. CE is available for 12 months after episode publication. Key Concepts There are two main types of stand-alone personal CGMs available in the US market – real-time (rtCGM) and intermittently scanning (isCGM). [1] These CGMs vary in their features such as sensor wear time, sensor warm up time, sensor application site, reader availability, approved age for use, fingerstick calibration, non-adjunctive FDA labeling, interconnectability with other technology such as insulin pumps, and drug interactions – these variabilities can be used in decision-making when selecting an appropriate CGM for a patient. [2-7] Based on the evidence for use, both types of CGMs (real-time and intermittently scanning) are recommended in patients with Type 1 and Type 2 diabetes who are on multiple-daily insulin or continuous insulin infusion (pump), patients with Type 2 diabetes on basal insulin therapy, and as adjunct use in patients with diabetes who are pregnant. The strength of recommendations in general is stronger for real-time CGMs than for intermittently scanning CGMs. [1,11] These recommendations are supported by the evidence that CGMs can help improve glucose control, reduce risk of hypoglycemia, diabetes-related hospitalizations, and patient/caregiver satisfaction. Pharmacists play an integral role in education, on-going support, data interpretation, and resulting disease management in patients who qualify for CGM use and providers who care for patients with diabetes. [14] The ambulatory glucose profile is a standardized data output that informs understanding of glucose trends. [15] The recommended goal for most patients is to maintain a glucose range between 70-180 mg/dL with at least 70% of time spent in this range with variability coefficient of no more than 36%.

161 - My Loss Is Your Gain! How Drug Repository Programs Are Helping Patients Afford High-cost Medications
In this episode, we interview Dr. Shannon Rotolo and Dr. Alex Berce regarding Illinois and Wisconsin drug repository programs – these are programs that allow certain medications to be donated to participating sites and then redistributed to patients at a very low dispensing cost. Key Concepts Drug repository programs allow participating sites to accept certain donated medications and redistribute these medications to needy patients at a very low dispensing cost. Drug repository programs are regulated by state law and the specifics of the process do vary by state. In Illinois and Wisconsin, donated medications must be in their original containers with tamper-evident packaging, cannot be controlled substances, and must have a 90-day expiration window at the time of donation. Pharmacists can play an important role in advocating for patients and the profession of pharmacy. The involvement of pharmacists in legislation is critical to make sure that new laws are actually “functional” and can achieve their intended purpose.

160 - Dextromethorphan for Depression? Analyzing Data for Auvelity® in Major Depressive Disorder
In this episode, we discuss the evidence, safety, and place in therapy of Auvelity® (dextromethorphan-bupropion), a newly approved antidepressant with a unique mechanism of action and interesting pharmacokinetic considerations. Key Concepts Auvelity® (bupropion-dextromethorphan) was FDA approved in 2022 for major depressive disorder (MDD). The bupropion component inhibits CYP2D6 metabolism and increases serum concentrations of dextromethorphan. The proposed mechanism of benefit in MDD is via dextromethorphan (as an NMDA antagonist) and possibly with bupropion (as a dopamine/norepinephrine reuptake inhibitor). Although the bupropion component in Auvelity® is being used for its drug interaction, the dose is a therapeutic dose and carries several warnings and precautions, including the risk of seizure and hypertension. In short (6-week) clinical trials, Auvelity® improved depression symptoms quickly (within 1-2 weeks), which is faster than many other antidepressants. Auvelity® is associated with dizziness, anxiety, hyperhidrosis, nausea, headache, diarrhea, and dry mouth. As a CYP2D6 inhibitor, the bupropion component of Auvelity® will cause drug interactions with many other medications, including some antidepressants, antipsychotics, and opioid analgesics (among others).

159 - A Breath of Fresh Air: Big Changes to the 2023 GOLD Guidelines for COPD
In this episode, we highlight important changes to the 2023 GOLD Guidelines for COPD. In particular, we discuss a revision to the GOLD group classification system and the preferred initial therapies in patients with COPD. Key Concepts The newest GOLD COPD guidelines now recognize three GOLD groups – “A”, “B”, and “E”. Group “E” (formerly groups C and D) are patients with frequent exacerbations (defined as 2 or more in the past 12 months or 1 exacerbation requiring hospitalization). For group “E” patients, the preferred initial inhaler regimen is a LABA+LAMA. Triple therapy (LABA+LAMA+ICS) can be considered if blood eosinophils are elevated. “Triple therapy” (LABA+LAMA+ICS) has gained traction based on the IMPACT and ETHOS trials – this regimen reduced exacerbations and mortality compared to LABA+LAMA and LABA+ICS. With an exploding market of new COPD inhalers, the role of the pharmacist is even more critical to help identify affordable medications and provide patient education for proper inhaler technique.

158 - PADing Your Understanding of Peripheral Arterial Disease: A Brief Treatment Overview
In this episode, we will discuss all things peripheral arterial disease – definitions, staging, clinical presentation, risk factors, goals of therapy, and guideline-directed medication therapy recommendations including the newest evidence for the use of DOACs. Key Concepts Addressing modifiable risk factors (weight loss, smoking cessation, blood pressure and blood glucose control, dyslipidemia, structured exercise program, etc.) are recommended for the treatment of PAD. Single antiplatelet therapy with either aspirin 81 mg or clopidogrel 75 mg daily are recommended in patients to reduce stroke, MI and other vascular deaths in symptomatic (1A) and asymptomatic patients (IIa- C-EO). Rivaroxaban 2.5 mg BID, when added to aspirin 81 mg daily, is superior to aspirin alone in preventing composite outcome of stroke, MI, and CV death in PAD patients with recent revascularization surgery for PAD but increases the risk of major bleeding. In the absence of heart failure, cilostazol is effective in improving symptoms, quality of life, and increasing walking distance in patients with intermittent claudication.

157 - Everything Will Be ao-K+: Potassium Formulations and Dosing for Hypokalemia
In this episode, we review the management of a patient with hypokalemia, including both inpatient and outpatient supplementation with potassium chloride supplements and what dosage forms are available for potassium repletion. Key Concepts Most diets will provide sufficient potassium to avoid hypokalemia. Hypokalemia usually occurs due to drug therapy (such as diuretics) or GI losses from severe vomiting or diarrhea. In patients with chronically low potassium, supplements are dosed to increase dietary intake of potassium by about 20-40 mEq per day. For acute repletion, 10 mEq of potassium should increase serum potassium by about 0.1 mEq/L. Over-the-counter potassium (as potassium gluconate) contains a very small amount of potassium (2.5 mEq). Potassium chloride powders and liquids (like salt substitutes) taste terrible and are poorly tolerated. Most patients will replete potassium via slow-release tablets (Klor-Con or Klor-Con M) or via potassium chloride IV infusions. Most IV fluids do not contain any potassium at all (or very little potassium). Patients receiving these IV fluids who are NPO will eventually become hypokalemic. Certain maintenance fluids do contain potassium – most patients will receive about 40 mEq of potassium per day with these IV fluids.

In this episode, we will define Digital Health, its categories and examples, describe how pharmacists are involved in DH practice, opportunities and limitations and future of DH. We will also discuss what implications DH has for educators, educational institutions, student pharmacists, pharmacists, and practice of pharmacy in general. Key Concepts Digital Health is currently a broad umbrella category that uses mobile health, telehealth, web-based platforms, personalized medicine, and IT to provide scalable patient care. There are several focused areas within DH that would impact pharmacy practice by warranting pharmacist oversight or collaborative insights. There is positive data for pharmacist-led DH interventions using mobile apps and web-based tools, but the use of telehealth modality has mixed results. Pharmacists need to stay current in their knowledge and skills for utilizing DH tools in integrative and collaborative patient care. References Aungst TD, Franzese C, Kim Y.

155 - Oncology 911: Tumor Lysis Syndrome as an Oncologic Emergency
In this episode, we invite Dr. Amir Ali, PharmD, BCOP to discuss with us the pathophysiology, risk factors, prevention, and treatment clinical pearls of tumor lysis syndrome TLS). Key Concepts TLS is caused by rapid cell death of cancerous cells that results in intracellular contents “spilling” into the blood – this leads to high serum uric acid, high serum potassium, high serum phosphate, and LOW calcium. These laboratory abnormalities cause acute kidney injury (via crystal formation in the kidney), arrhythmias (from hyperkalemia), and seizures (from high phosphate and low calcium). Patients at highest risk for TLS are those with hematologic malignancies (lymphomas and leukemias), especially if WBC or LDH labs are very high. Prevention is the Key! The primary prevention approach for TLS is hydration, allopurinol, and sometimes a low dose of rasburicase. The treatment of TLS involves more aggressive hydration and rasburicase.

154 - What’s New With Paxlovid: Drug Interactions, Pharmacist Prescribing, “Paxlovid Mouth”, and a Brief Drug Review
In this episode, we review Paxlovid (nirmatrelvir/ritonavir) from the perspective of its pharmacology, efficacy, safety, pharmacists’ authority to prescribe, drug interactions, and rebound symptoms after Paxlovid therapy. Key Concepts Paxlovid is the preferred outpatient therapy for COVID-19 in patients at high risk for progressing to severe COVID-19. It likely has similar efficacy to IV monoclonal antibodies and IV outpatient remdesivir but differences in vaccination rates and patient populations makes a direct comparison difficult. The 5-day course of Paxlovid is generally well tolerated. “Paxlovid mouth” (dysgeusia) is relatively common and is characterized by a terrible metallic or garbage-like taste in the mouth during therapy. As of July 2022, licensed pharmacists have the authority to assess patients for Paxlovid and prescribe the therapy; however, Medicare/Medicaid reimbursement has not clearly established how reimbursement of clinical services can occur. “Rebound” COVID-19 symptoms may or may not be due to Paxlovid (versus the natural course of the disease).

In this episode, we will discuss mechanism, pharmacokinetics, efficacy, safety, and possible place in therapy for tirzepatide (Mounjaro), a new treatment for type 2 diabetes. Key Concepts Tirzepatide is a novel GIP and GLP-1 receptor agonist resulting in glucose-dependent secretion of insulin and a decrease in glucagon secretion. This medication was FDA approved in May 2022 for the treatment of type 2 diabetes as an adjunct to diet and exercise. It is available as a long-acting once weekly pen injection to be administered subcutaneously. Current efficacy data exist from a 40-week trial which showed that tirzepatide was superior to semaglutide in A1c reduction and weight loss. The most common adverse effects of tirzepatide include GI concerns such as nausea, vomiting, and diarrhea as well as hypoglycemia. References Frias JP, Davies MJ, Rosenstock J, et al.
