Category C

DIULO

Thiazide Diuretic

Category C

Head-to-Head

Clinical Matrix

Mechanism of Action

Chlorothiazide inhibits the Na+-Cl- symporter in the distal convoluted tubule, reducing sodium and chloride reabsorption and promoting diuresis. It also causes vasodilation by reducing peripheral vascular resistance.

Inhibits the Na+/Cl- symporter in the distal convoluted tubule of the nephron, reducing reabsorption of sodium and chloride, leading to increased diuresis and decreased extracellular fluid volume.

Clinical Dosing

500 mg to 1000 mg orally or intravenously once or twice daily.

2.5 mg orally once daily, may increase to 5 mg once daily after 4 weeks if needed.

Direct Interaction

None Documented

Half-Life

Terminal half-life: 45–120 minutes (prolonged in renal impairment); clinical context: short duration requires frequent dosing
