Telisa 40 mg Tablet is an antihypertensive medication containing Telmisartan, a long-acting angiotensin II receptor blocker (ARB). It is primarily used to treat high blood pressure (hypertension) and helps prevent heart attacks, strokes, and kidney problems. Telisa works by relaxing blood vessels so blood can flow more easily, reducing the workload on the heart. It is also prescribed to lower the risk of cardiovascular events in high-risk patients with diabetes or heart disease history.
