In this episode, we review the pharmacology, indications, adverse effects, monitoring, and unique drug characteristics of angiotensin receptor blockers (ARBs). Key Concepts ARBs are equally efficacious as ACE inhibitors when used for hypertension, heart failure with reduced ejection fraction (HFrEF), chronic kidney disease (CKD) with proteinuria, and post-MI care. Some limited evidence suggests that they might be better in reducing albuminuria in patients with diabetes. ARBs are generally better tolerated than ACEi due to a lower risk of angioedema and dry cough. While most ARBs...

In this episode, we discuss the diagnosis and treatment of resistant hypertension, including a newer endothelin receptor antagonist (ERA) called aprocitentan (Tryvio®). Key Concepts The diagnosis of true resistant hypertension is based on requiring more than 3 antihypertensives (ACE inhibitor or ARB + calcium channel blocker + diuretic) to achieve goal BP, ruling out inaccurate BP readings, and ensuring patient adherence to their antihypertensive therapy. Non-pharmacologic therapy (especially dietary sodium restriction), medication adherence, and lifestyle changes are critical to the...

In this episode, we discuss the very early stages of drug targets and drug development with Dr. Mohd Shahid, PhD. Dr. Shahid’s research involves the IER3 gene, which is an important modulator of the body’s inflammatory response via its action in major immune cells, including macrophages and T-cells, and plays a role in metabolic disorders such as obesity, diabetes, and atherosclerosis, revealing a previously unknown function of this protein. Key Concepts Drug development is a multi-decade journey – human clinical trials occur very late in the process. Drug development often starts...

In this episode, we review the new 2025 ACC/AHA Acute Coronary Syndrome (ACS) guidelines, with a particular focus on guideline recommendations for analgesics, P2Y12 inhibitors, parenteral anticoagulation, and lipid management. Key Concepts Nitrates and opioids are recommended for symptomatic relief of chest pain. Some patients may not be appropriate for nitrates (e.g. recent PDE-5 inhibitor use, hypotension, or right ventricular infarction). Opioids are used for nitrate-refractory angina but have a theoretical risk of delaying the effect of oral antiplatelet medications. Prasugrel and...

In this episode, we interview Morgan Anderson, PharmD, BCIDP, a graduate of the RFUMS College of Pharmacy, about her career path from a pharmacy resident, emergency medicine specialist, infectious diseases specialist, and now a medical sciences liaison. The views, thoughts, and opinions expressed in this podcast are solely Dr. Anderson’s own and do not necessarily reflect the views, positions, or policies of her employer. This podcast is conducted in a personal capacity, and any reference to her professional background is for context only. Key Concepts Having a wide breadth of skills and...

In this episode, we discuss the efficacy and safety of semaglutide and tirzepatide for weight loss with a particular focus on the legal, regulatory, and safety aspects of these “compounded” GLP-1 receptor agonist medications. Key Concepts Semaglutide and tirzepatide have growing evidence that their clinical benefits extend beyond the treatment of diabetes. Evidence now shows benefit in a variety of obesity-related disease states regardless of a patient’s diabetes status. Insurance coverage and drug cost is a major barrier to these medications, with cash prices exceeding $1000 per month...

In this episode, we review the recommendations from the 2024 SCCM/ASHP stress ulcer prophylaxis guidelines and highlight three of the more recent landmark critical care trials investigating the role of stress ulcer prophylaxis. Key Concepts After 25 years, the stress ulcer prophylaxis guidelines have been updated by SCCM and ASHP. These guidelines make 13 recommendations in a PICO format. Three large, landmark randomized controlled trials (SUP-ICU, PEPTIC, and REVISE) have significantly contributed to the body of literature regarding stress ulcer prophylaxis. The SCCM/ASHP guidelines...

In this episode, we discuss the approach to deprescribing for several drugs such as benzodiazepine receptor agonists, cholinesterase inhibitors, memantine, antipsychotics, and antihyperglycemics. Key Concepts Medication appropriateness including indication and risk vs. benefit should be evaluated for all stages of life; however, more importantly in older individuals to address polypharmacy. There is an emerging trend of deprescribing networks that conduct research and provide evidence-based recommendations for how to deprescribe certain medications used for specific indications....

In this episode, we review the pharmacology, pharmacokinetics, adverse effects, monitoring, medicinal chemistry, and more of loop diuretics. Key Concepts Loop diuretics (furosemide, torsemide, bumetanide, ethacrynic acid) are the most potent type of diuretic and are used to relieve edema. Loop diuretics cause an increased loss of sodium, chloride, potassium, hydrogen, magnesium, and calcium ions into the urine. Excessive loss of these ions manifests as hypokalemia, hypomagnesemia, and metabolic alkalosis. Loop diuretics have an S-shaped dose response curve – a minimum dose is required for...

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...
info_outlineIn 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.
