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. This medication can help reduce the risk of stroke and heart attack in patients with certain heart conditions. It is usually taken once daily, and like all medications, it may have side effects. Patients should consult their healthcare provider for proper dosage and to discuss any potential interactions with other medications.
