Last Updated: December 14, 2018

Telmisartan belongs to a family of drugs that are used to treat high blood pressure. It is also effective in reducing the risk of serious conditions such a stroke, heart attacks, heart conditions and even death. Telmisartan helps maintain optimal blood pressure levels in a person’s body. In patients who suffer from hypertension, it can lower the blood pressure.

Telmisartan works by widening and dilating the blood vessels, which relaxes them. It also helps the kidney flush out excess salt and water, thus reducing the blood pressure. Therefore, Telmisartan is highly effective in treating hypertension.

Telmisartan is a drug that is also known as an Angiotensin receptor blocker or an ARB. This drug is used to treat hypertension or high blood pressure. It is also given to patients, to reduce their risk of developing conditions such as heart disorders, a stroke and heart attacks. The Telmisartan works, by blocking the effect of Angiotensin. It prevents the activation of a receptor, by the Angiotensin II hormone that would usually result in a slight increase of the blood pressure, when it is low. It lowers blood pressure by dilating and relaxing the muscles of the blood vessels. This enables your kidney to eliminate the excess of water and salt.
