Understanding ARBs: Angiotensin Receptor Blockers for Blood Pressure & Heart Failure

ARB stands for angiotensin receptor blocker. ARBs are a class of medications used to treat high blood pressure (hypertension) and heart failure. They work by blocking the action of angiotensin II, a hormone that causes blood vessels to narrow. This can help to lower blood pressure and improve blood flow to the heart and other organs.
