Telmisartan tablets IP 40 mg are used to treat:

1. Hypertension (high blood pressure): to reduce blood pressure and prevent complications like heart attack, stroke, and kidney disease.
2. Heart failure: to reduce the risk of hospitalization and death in patients with chronic heart failure.
3. Cardiovascular risk reduction: to reduce the risk of cardiovascular events like heart attack, stroke, and death in patients with cardiovascular disease or diabetes.

Telmisartan, an angiotensin receptor blocker (ARB), works by:

1. Blocking the action of angiotensin II, a hormone that constricts blood vessels and increases blood pressure.
2. Relaxing blood vessels, improving blood flow, and reducing blood pressure.
3. Reducing inflammation and oxidative stress in the body.

This medication is often used alone or in combination with other medications, such as diuretics, calcium channel blockers, or ACE inhibitors. Telmisartan 40 mg tablets are usually taken once daily, and the dosage may vary depending on the individual patient’s needs. Always consult a healthcare professional for proper diagnosis and treatment.
