Mechanism of action

Amlodipine is a dihydropyridine calcium channel blocker that inhibits L-type calcium channels in vascular smooth muscle, causing vasodilation and reduced peripheral vascular resistance. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium reabsorption in the distal convoluted tubule, promoting natriuresis and reducing circulating blood volume. The combination provides complementary antihypertensive effects through different mechanisms.
