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 fa

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 rela

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 y

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 servi

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

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.  References Ishani A, Cushman WC, Leatherman SM, et al. Chlorthalidone vs. Hydrochlorothiazide for Hypertension–Cardiovascular Events. N Engl J Med 2022; 387:2401-2410.

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

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. Amon

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,

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.

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

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, anxi

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.

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, q

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 potass

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. Digital health implications f

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. References Coiffier B, Altman A, Pui CH, Younes A, Cairo MS. Guidelines for the m

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

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. Tirzepatide versus Semaglutide Once Weekly in Patients with Type 2 Diabetes. N Engl J Med. 2021;385:503-515. https://www.nejm.org/doi/full/10.1056/NEJMo

In this episode, we will discuss the rationale behind the FDA approval of two new pneumococcal conjugate vaccines (PCV20 and PCV15), the characteristics of these vaccines, their place in therapy as recommended by the ACIP, and subsequent CDC immunization schedule changes. Key Concepts Pneumococcal disease is mainly caused by various serotypes of Streptococcus pneumoniae and presentation can vary from mild forms (sinusitis, otitis media) to more severe (pneumonia, bacteremia, or meningitis). Previously we used PCV13 and PPSV23 vaccines for adults ages 18 years and older for prevention of pneumococcal disease, but the recommendations were rather complicated based on age, underlying condition/immune status, and vaccination status.  Two new conjugate-type pneumococcal vaccines, PCV20 (Prevnar 20) and PCV15 (Vaxneuvance) are now approved by the FDA and were recently added to the CDC’s adult immunization schedules. These updated recommendations are more simplified where adults with high-risk conditions and those a
