Angiotensin receptor blockers (ARBs)

Angiotensin receptor blockers (ARBs) are medications used to lower blood pressure and protect the heart. They work by blocking a protein called angiotensin II, which narrows blood vessels and increases blood pressure. By preventing this narrowing, ARBs help relax blood vessels, making it easier for blood to flow and reducing the heart’s workload. They are commonly prescribed for high blood pressure, heart failure, and certain kidney issues. ARBs are generally well-tolerated and can help prevent complications related to elevated blood pressure, such as strokes and heart attacks.
