Angiotensin II receptor blockers (ARBs): Overview

ARBs (angiotensin II receptor blockers) block a hormone that makes blood vessels narrow. As a result, the blood vessels relax and widen. This lowers blood pressure. ARBs also put more water and salt into the urine. This also lowers blood pressure.

ARBs can treat:
