angiotensin II receptor antagonists

Angiotensin II receptor antagonists, often called ARBs, are medications that help lower blood pressure and protect the heart. They work by blocking the effects of a hormone called angiotensin II, which causes blood vessels to squeeze tight, increasing blood pressure. By blocking this hormone, ARBs relax and widen blood vessels, making it easier for blood to flow. This helps reduce the risk of heart attacks, strokes, and other cardiovascular issues. Common examples include losartan and valsartan, and they are often prescribed for conditions like hypertension and heart failure.
