What does ARB stand for?

1. Angiotensin Receptor Blocker (ARB)

Definition and Purpose

Angiotensin Receptor Blockers (ARBs) are a class of medication used primarily to treat high blood pressure and heart failure. They work by blocking the action of angiotensin II, a hormone that narrows blood vessels, which helps to relax and widen the blood vessels.

Mechanism of Action

ARBs block the angiotensin II receptors on blood vessels, preventing the hormone from binding and exerting its effects. This leads to vasodilation, or the widening of blood vessels, which reduces blood pressure and decreases the workload on the heart.

Common ARBs and Uses

Common ARBs include losartan, valsartan, and irbesartan. These medications are also used in the management of conditions such as chronic kidney disease and diabetic nephropathy. They are often prescribed when patients cannot tolerate ACE inhibitors.


ARBs are critical in managing hypertension and heart failure, reducing the risk of stroke, heart attack, and kidney damage. They are an essential component of cardiovascular treatment protocols, improving patient outcomes and quality of life.
