Telmisartan is a prescription medication primarily used to manage high blood pressure (hypertension) and reduce the risk of cardiovascular events such as heart attack and stroke. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs). By blocking the effects of angiotensin II—a hormone that causes blood vessels to tighten—Telmisartan helps relax blood vessels, lowering blood pressure and improving blood flow.
