Used primarily to treat high blood pressure (hypertension), Telmisartan helps lower the risk of heart attack and stroke by relaxing blood vessels, allowing blood to flow more smoothly. It is also used in patients with cardiovascular disease or type 2 diabetes who have organ damage, as it provides protective effects on the heart and kidneys. Telmisartan improves insulin sensitivity, which can be beneficial in managing metabolic syndrome. It is often prescribed when long-lasting blood pressure control is needed, due to its extended duration of action.
