Telmisartan tablets IP 20 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. Cardiovascular risk reduction: to reduce the risk of cardiovascular events like heart attack, stroke, and death in patients with cardiovascular disease or diabetes.
3. Heart failure: to reduce the symptoms and improve the heart’s functioning in patients with chronic heart failure.
4. Kidney disease: to slow the progression of kidney disease in patients with hypertension, diabetes, or kidney damage.

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.

The 20 mg dose is often used for:

1. Initial treatment: as a starting dose for patients new to telmisartan therapy.
2. Dose titration: to gradually increase the dose for patients who require a higher dose.
3. Patients with renal impairment: as a lower dose may be necessary for patients with kidney disease.

Remember, always consult a healthcare professional for proper diagnosis and treatment, as the uses and dosages may vary depending on individual patient needs.
