Chlorthalidone is a thiazide-like diuretic, structurally different from thiazides but providing a longer duration of action, making it one of the most effective drugs for chronic hypertension. It is widely used in monotherapy and fixed-dose combinations (FDCs) with ACE inhibitors, ARBs, beta-blockers, and potassium-sparing diuretics.
Chlorthalidone works primarily in the distal convoluted tubule by: • Inhibiting Na⁺/Cl⁻ symporter, reducing sodium and chloride reabsorption. • Increased urinary excretion of Na⁺, Cl⁻, water → diuresis. • Reduces plasma volume → lower cardiac output → antihypertensive effect.
