Angiotensin II Receptor Blockers (ARBs)

Angiotensin II Receptor Blockers (ARBs) are medications used to help lower high blood pressure and protect the heart. They work by blocking a hormone called angiotensin II, which narrows blood vessels and raises blood pressure. By preventing this hormone from acting, ARBs help blood vessels relax and widen, making it easier for blood to flow and reducing the workload on the heart. They are often prescribed for conditions like hypertension and heart failure and are generally well tolerated with fewer side effects compared to other blood pressure medicines.
