Exforge Tab 5/160mg is a prescription medication used to treat high blood pressure (hypertension). Each tablet contains two active ingredients: amlodipine besylate, a calcium channel blocker, and valsartan, an angiotensin II receptor blocker. Amlodipine works by relaxing the blood vessels, making it easier for the heart to pump blood, thereby lowering blood pressure. Valsartan blocks the action of certain natural substances that tighten blood vessels, allowing for smoother blood flow. This dual action effectively lowers blood pressure, reducing the risk of cardiovascular events such as strokes and heart attacks.
