Mechanism of action

ARBs selectively antagonize the AT1 receptor, which is responsible for the vasoconstrictive and aldosterone-releasing effects of angiotensin II. By blocking this receptor, ARBs cause vasodilation, reduce peripheral vascular resistance, and lower blood pressure. They also reduce sodium reabsorption in the kidneys and have cardioprotective effects in heart failure and post-myocardial infarction patients.
