About Composition

Telmisartan-

Telmisartan belongs to angiotensin receptor blocker. It is used in the treatment of hypertension.
It reduces the pressure generated in the arteries

Amlodipine Besylate-

Amlodipine besylate have an antioxidant property which stimulate the production of nitric acid and acts as vasodilatory effect which lowers the blood pressure.

Hydrochlorothiazide-
