Loop Diuretics: Pharmacology Made Easy & Clinically Relevant

Описание: In this This Is Why with Dr. Busti pharmacology review, Dr. Busti breaks down the science and clinical application of loop diuretics—a cornerstone drug class for managing fluid overload and edema. Drawing on his experience as a nurse, pharmacist, physician, and educator, he explains how these agents work at the loop of Henle, their pharmacokinetic differences, and why understanding their mechanism helps prevent common pitfalls like electrolyte disturbances, diuretic resistance, and hemodynamic instability.

This session translates complex renal physiology into clear, clinically relevant knowledge—connecting the why behind loop diuretics’ powerful therapeutic effects and potential risks in both inpatient and outpatient care.
