What does it do?

Telmisartan belongs to the class of angiotensin II receptor blockers and is used in medications to lower blood pressure. It is primarily prescribed to control blood pressure in patients with hypertension.

Telmisartan blocks the action of a substance called angiotensin II, which constricts blood vessels, leading to vasodilation. This results in lower blood pressure and reduced strain on the heart.
