Telpro 40 mg Tablet contains Telmisartan, an angiotensin II receptor blocker (ARB) used to manage high blood pressure (hypertension) and reduce the risk of cardiovascular events such as heart attacks and strokes. By blocking the action of angiotensin II, a substance that narrows blood vessels, Telmisartan helps relax blood vessels, thereby lowering blood pressure and improving blood flow.
