Valsartan is an angiotensin II receptor blocker (ARB) used to manage high blood pressure, heart failure, and certain post–heart attack conditions. By blocking the action of angiotensin II, a hormone that narrows blood vessels, valsartan helps relax and widen the vessels, lowering blood pressure and improving circulation.
This improved blood flow supports heart efficiency, lowers the risk of cardiovascular complications, and can help protect the kidneys in patients with diabetes and hypertension. Valsartan is also prescribed to improve survival after a heart attack and may be used off-label for chronic kidney disease management.
