Angiotensin II Blockers

Angiotensin II blockers, also known as ARBs (Angiotensin Receptor Blockers), are medications that help manage high blood pressure and heart failure. They work by blocking the action of a hormone called angiotensin II, which usually narrows blood vessels and raises blood pressure. By preventing this hormone from binding to its receptors, ARBs relax and widen the blood vessels, making it easier for the heart to pump blood and lowering blood pressure. This can help protect the kidneys and reduce the risk of cardiovascular problems. ARBs are often prescribed when other blood pressure medications are not suitable or effective.
