Real Life Pharmacology - Pharmacology Education for Health Care Professionals

This podcast is designed to help pharmacy and nursing learners cut through the noise and focus on the high-yield concepts that matter most when it comes to angiotensin receptor blockers (ARBs) and thiazide diuretics. These two medication classes show up constantly on exams and in clinical practice, yet small details about their mechanisms, adverse effects, and monitoring parameters are often where test questions try to trip you up. Each episode is built to reinforce those key points in a clear, practical way. We’ll break down how ARBs and thiazide diuretics work, why they are commonly used in hypertension and other disease states, and how to quickly differentiate them from similar drug classes. Special attention is given to classic exam “gotchas,” such as electrolyte changes, renal considerations, and patient populations where these medications are especially beneficial or should be used with caution. Beyond test prep, this podcast emphasizes real-world practice pearls that translate directly to patient care. You’ll hear concise explanations of what to monitor, what side effects matter most clinically, and how to recognize problems early. These insights are especially helpful for nurses, pharmacy students, and new clinicians who want to feel confident applying pharmacology knowledge at the bedside or in clinic. Whether you’re studying for boards, preparing for a pharmacology exam, or just looking to sharpen your clinical skills, this podcast delivers focused, high-yield content in an easy-to-follow format. By the end of each episode, you’ll walk away with practical takeaways that improve both your test performance and your day-to-day medication management.

Welcome to today’s episode, where we dive into two cornerstone classes of antihypertensives: ACE inhibitors and calcium channel blockers. These drugs are among the most frequently prescribed agents in both primary care and specialty settings, making a solid understanding of their practical nuances essential for clinicians, pharmacists, and learners alike. In this episode, we’ll break down the most important clinical pearls that can immediately improve your prescribing confidence and patient care. We’ll start with ACE inhibitors, a class often selected for patients with hypertension, heart failure, diabetes, and chronic kidney disease. While widely effective, ACE inhibitors come with monitoring requirements and predictable side effect profiles that clinicians must recognize early. We’ll highlight what changes in renal function are acceptable, how to navigate issues like hyperkalemia and cough, and when switching to an ARB may be the safest option. Next, we’ll move into calcium channel blockers, emphasizing the differences between dihydropyridines and non-dihydropyridines—two groups with distinct effects and unique considerations. I outline amlodipine’s adverse effects and how to navigate a patient who is experiencing edema. By the end of this episode, you’ll walk away with a set of high-yield, easy-to-apply pearls that you can use in your next patient encounter. If you use antihypertensives and treat hypertension, heart failure, arrhythmias, or chronic kidney disease, this episode will help sharpen your understanding of these foundational therapies and elevate your medication management strategies.

Moxifloxacin is a fourth-generation fluoroquinolone that works by inhibiting bacterial DNA gyrase and topoisomerase IV—two enzymes essential for DNA replication, repair, and transcription. By blocking both targets, it provides broad-spectrum activity against gram-positive, gram-negative, and atypical pathogens. Its enhanced gram-positive coverage, especially against Streptococcus pneumoniae, distinguishes it from earlier fluoroquinolones like ciprofloxacin. Pharmacokinetically, moxifloxacin has excellent oral bioavailability, meaning the PO and IV doses are essentially interchangeable. It distributes well into tissues like the lungs and sinuses, making it a frequent choice for respiratory infections. With a long half-life of about 12 hours, once-daily dosing is standard. Adverse effects are similar to the fluoroquinolone class, with concerns including tendonitis and tendon rupture, QT interval prolongation, CNS effects like confusion or agitation—particularly in older adults—and the risk of peripheral neuropathy. Moxifloxacin is especially notable for a higher propensity toward QT prolongation compared with some of its peers, making it important to avoid in patients with existing QT issues or those taking other QT-prolonging medications.

On this episode of the Real Life Pharmacology Podcast, I cover albuterol pharmacology, adverse effects, and a rare indication for this classic respiratory medication. Albuterol is a short-acting beta-2 adrenergic agonist (SABA) that works by stimulating beta-2 receptors in the bronchial smooth muscle. This stimulation activates adenylate cyclase, increases cyclic AMP, and leads to relaxation of airway smooth muscle. The end result is rapid bronchodilation, making albuterol effective for quick relief of acute bronchospasm in conditions such as asthma and COPD. Common adverse effects occur due to both beta-2 and some unintended beta-1 receptor stimulation. Patients may experience tremors, nervousness, headache, or tachycardia. Higher doses or frequent use can lead to hypokalemia because beta-2 stimulation drives potassium into cells. Some individuals may also report palpitations or feelings of anxiety. These effects are generally mild and transient but can be more pronounced in older adults, those with cardiovascular disease, or when albuterol is used excessively. Albuterol has several clinically relevant drug interactions. Concomitant use with non-selective beta-blockers (such as propranolol) can blunt its bronchodilatory effect and may precipitate bronchospasm in susceptible individuals. Using albuterol with other sympathomimetics can enhance cardiovascular stimulation, increasing the risk of tachycardia or hypertension. Diuretics, especially loop or thiazide types, may compound albuterol-induced hypokalemia. Additionally, monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants can potentiate the effects of albuterol and increase the risk of cardiovascular adverse reactions.

Glycopyrrolate is an anticholinergic medication commonly used to reduce excessive secretions, particularly in palliative care, postoperative settings, and certain neurologic conditions. It works by blocking acetylcholine at muscarinic receptors, which decreases salivary and respiratory secretions. Clinically, glycopyrrolate is often used to manage terminal respiratory secretions (“death rattle”). Adverse effects of glycopyrrolate are primarily related to its anticholinergic properties. These may include dry mouth, constipation, urinary retention, blurred vision, tachycardia, and decreased sweating. While it has fewer central effects than agents like scopolamine, caution is still warranted in patients with glaucoma, gastrointestinal obstruction, or significant urinary retention risk. Monitoring hydration and bowel function is important, especially in elderly or frail patients. Dosing strategies depend on the clinical need. In palliative care, low doses may be given subcutaneously or intravenously every 4–6 hours as needed, while oral dosing is common for chronic sialorrhea. Clinicians should consider the patient’s overall medication burden, as cumulative anticholinergic load can worsen cognitive impairment and contribute to falls or constipation. I discuss drug interactions and other commonly used medications that may contribute to anticholinergic burden.
