Telmisartan is an oral prescription medication belonging to the class of drugs called angiotensin II receptor blockers (ARBs). It is primarily used to treat high blood pressure (hypertension) and to reduce the risk of heart attack and stroke in high-risk patients. 

Key Information

• Uses: Telmisartan is indicated for treating high blood pressure and reducing the risk of cardiovascular events (like heart attack and stroke) in adults aged 55 or older with existing vascular disease or high-risk diabetes. It may also be used to manage heart failure or diabetic nephropathy in some cases.

• Mechanism: It works by blocking the action of a natural substance in the body (angiotensin II) that causes blood vessels to narrow. This relaxes the blood vessels, allowing blood to flow more smoothly, which lowers blood pressure and eases the heart's workload.

• Dosage: The usual starting dose for adults with high blood pressure is 40 mg once daily, with a typical range of 20 mg to 80 mg. For cardiovascular risk reduction, the recommended dose is typically 80 mg once daily.
