Telvas 40 Tablet 15 belongs to a class of drugs known as angiotensin II receptor blockers, which are used to treat adults with hypertension (high blood pressure). It is also used to lower the risk of a heart attack or stroke in adults. Essential hypertension is a medical condition in which blood pressure in the arteries is persistently elevated for no apparent reason. Heart attacks and strokes, on the other hand, are caused by blocked blood flow to the heart or brain, respectively. It works by inhibiting the action of a hormone called angiotensin II in the body, which causes blood vessel narrowing and high blood pressure. As a result, it both widens and relaxes blood vessels.Disclaimer:For More Information Contact Your Physician
