In this episode, we discuss the diagnosis and treatment of resistant hypertension, including a newer endothelin receptor antagonist (ERA) called aprocitentan (Tryvio®).

Key Concepts

1. 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.
2. Non-pharmacologic therapy (especially dietary sodium restriction), medication adherence, and lifestyle changes are critical to the treatment of resistant hypertension.
3. The preferred 4th line option for most patients with resistant hypertension is spironolactone.
4. After adding spironolactone, additional therapies are based on expert opinion and patient-specific factors. These additional therapies may include beta blockers, alpha-2 agonists, alpha-1 blockers, hydralazine, minoxidil, and aprocitentan.

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

1. Drug development is a multi-decade journey – human clinical trials occur very late in the process. Drug development often starts before a drug molecule is even conceived by identifying potential drug targets.
2. Chronic inflammation is important for a variety of diseases, including obesity and atherosclerosis. Dr. Shahid's work focuses on a specific gene, Immediate Early Response 3 Gene (IER3 or IEX-1), and its role in modulating the inflammatory response in these disease states.
3. The research process frequently leads to unexpected discoveries and new lines of inquiry. With Dr. Shahid, his work in obesity and inflammation actually led to a new understanding of the IER3's role in the interplay between macrophages, inflammation, and energy expenditure.

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

1. 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.
2. Prasugrel and ticagrelor are preferred P2Y12 inhibitors over clopidogrel in most patients. Patient-specific factors, including the use of PCI, play a role in P2Y12 inhibitor selection.
3. Anticoagulation with heparin is recommended in nearly all acute coronary syndrome (ACS) scenarios. Alternative anticoagulants may be used depending on whether PCI/CABG is planned and whether the anticoagulant is used prior to PCI/CABG ("upstream") or during the PCI procedure itself.
4. LDL goals after ACS have changed again. All ACS patients should have an LDL goal

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

1. Having a wide breadth of skills and making yourself marketable is important when transitioning between jobs or career paths. Skills like communication and teamwork can be improved and are applicable to a wide variety of careers within pharmacy.
2. Medical Science Liaisons (MSLs) are a common role for pharmacists in the pharmaceutical industry. MSLs are field-based roles within the medical affairs department of the company. MSLs are medical and scientific experts who build collaborative relationships with key thought leaders, facilitate exchange of scientific information and insights, and serve as a conduit between these thought leaders and other areas of the company.
3. Two common career paths to pharmacists becoming an MSL are via a fellowship program or after years in clinical practice. A fellowship program provides a more structured approach, including mentoring and networking, with access to a variety of areas of the company outside of medical affairs. A pathway after clinical practice is more self-directed with less structure, but provides pharmacists with a strong clinical background that can be helpful in an MSL role.
4. Being a scientific communicator, possessing strong emotional intelligence, and being adaptable are critical soft skills that are essential for success in an MSL role. These soft skills can be improved with practice!

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

1. 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.
2. Insurance coverage and drug cost is a major barrier to these medications, with cash prices exceeding $1000 per month in the US. There are many companies that are combining telemedicine visits with "compounded" GLP-1s to provide these medications at a reduced cost.
3. The Food, Drug, and Cosmetic (FD&C) Act regulates compounded drugs. These regulations provide the legal context for pharmacies to compound GLP-1 medications. These regulations describe who can compound, what drugs can be compounded, and other unique circumstances (e.g. compounding in the context of a drug shortage).
4. The FDA has released warnings regarding safety risks of compounded GLP-1s. The main safety concern is dosing errors; however, the warnings also include concerns of patients accessing drug products that are outside of the legal scope of the FD&C Act. The recent ADA statement recommends against the use of compounded GLP-1s due to these concerns.

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

1. After 25 years, the stress ulcer prophylaxis guidelines have been updated by SCCM and ASHP. These guidelines make 13 recommendations in a PICO format.
2. Three large, landmark randomized controlled trials (SUP-ICU, PEPTIC, and REVISE) have significantly contributed to the body of literature regarding stress ulcer prophylaxis.
3. The SCCM/ASHP guidelines recommend stress ulcer prophylaxis in patients with coagulopathy, shock, chronic liver disease, and possibly in neurocritical care patients. They do not specifically recommend prophylaxis in mechanically ventilated patients; this is a controversial recommendation.
4. The SCCM/ASHP guidelines equally prefer proton pump inhibitor (PPI) and histamine-2 receptor antagonists (H2RA) drug therapies given either intravenously or orally. The prophylaxis regimen should be continued until the indication for prophylaxis has resolved or the patient leaves the ICU.

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

1. 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.
2. 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.
3. Evidence-based deprescribing guidelines for PPIs, benzodiazepines, benzodiazepine receptor agonists, opioids, antipsychotics, cholinesterase inhibitors, memantine, and antihyperglycemics are available for patient-provider shared decision making.
4. A general deprescribing approach is gradual tapering of the drug leading to discontinuation over several weeks while monitoring patients for withdrawal symptoms or benefits of discontinuation.

In this episode, we review the pharmacology, pharmacokinetics, adverse effects, monitoring, medicinal chemistry, and more of loop diuretics.

Key Concepts

1. Loop diuretics (furosemide, torsemide, bumetanide, ethacrynic acid) are the most potent type of diuretic and are used to relieve edema.
2. 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.
3. Loop diuretics have an S-shaped dose response curve – a minimum dose is required for diuresis and a "ceiling" effect occurs at higher doses (leading to more ADRs). Doses should be individualized based on the clinical response of the patient.
4. Ethacrynic acid is incorrectly used in patients with a "sulfa" allergy. The other loop diuretics contain a sulfa moiety but are safe for use in patients with "sulfa" allergy (e.g. allergy to sulfamethoxazole-trimethoprim).
5. The TRANSFORM-HF trial strongly suggests that there is no clinical difference between furosemide and torsemide.

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

1. 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).
2. 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.
3. Many of the medications that are potentially inappropriate involve drugs that have anticholinergic properties and drugs that increase the risk of incoordination and falls.
4. 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.

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

1. 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.
2. 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.
3. 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).
4. 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.
