Valsartan is a medication primarily used to treat high blood pressure and heart failure. It belongs to a class of drugs known as angiotensin II receptor blockers (ARBs), which work by relaxing blood vessels, making it easier for the heart to pump blood. In addition to managing hypertension, valsartan may also help reduce the risk of heart attack and stroke in certain patients. It is often prescribed alongside lifestyle changes, such as diet and exercise, to improve overall cardiovascular health.
