Mechanism of action

Valsartan is an angiotensin II receptor blocker (ARB) that selectively antagonizes AT1 receptors, preventing angiotensin II-mediated vasoconstriction and aldosterone release, thereby reducing blood pressure and cardiac workload. Hydrochlorothiazide, when combined, enhances antihypertensive efficacy by inhibiting sodium reabsorption in the distal convoluted tubule, promoting urinary sodium and water excretion. The combination provides complementary mechanisms for blood pressure control.
