This episode of This Is Why with Dr. Busti dives deep into the pharmacology of thiazide diuretics, one of the most impactful and enduring drug classes in cardiovascular medicine. Dr. Busti unpacks pharmacology 101: the mechanism of action, pharmacokinetics, clinical uses, and side effects of agents like hydrochlorothiazide, chlorthalidone, indapamide, and metolazone — connecting each concept to the “why” behind their clinical application. Listeners will gain clarity on how these drugs fit into hypertension management, how renal physiology drives their effects, and what to monitor for safe, effective patient care.
The goals = Pharmacology made easy & pharmacology made relevant!
