How does Telmisartan work?
Telmisartan belongs to the class of drugs called angiotensin receptor blockers. Telmisartan blocks the vasoconstrictor and aldosterone-secreting effects of angiotensin II by selectively blocking the binding of angiotensin II to the AT1 receptor in many tissues, such as vascular smooth muscle and the adrenal gland. This helps in blood vessels to relax so that blood can flow more easily. Lowering high BP helps prevent heart attacks, strokes, and kidney problems. It is also used to improve the chance of living longer after a heart attack.
Telmisartan Uses and Benefits
- It is used to treat high blood pressure (Hypertension).
- It is used to treat heart failure.
- In people with type 2 diabetes and high blood pressure or albumin in the urine, valsartan is used to slow the worsening and the development of end-stage kidney disease.
- It may be given to you for other reasons. Talk with the health expert.
- Telmisartan is indicated for reduction of the risk of myocardial infarction, stroke, or death from cardiovascular causes in patients 55 years of age or older at high risk of developing major cardiovascular events who are unable to take ACE inhibitors.
- High risk for cardiovascular events can be evidenced by a history of coronary artery disease, peripheral arterial disease, stroke, transient ischemic attack, or high-risk diabetes (insulin-dependent or non-insulin dependent) with evidence of end-organ damage. It can be used in addition to other needed treatment (such as antihypertensive, antiplatelet or lipid-lowering therapy).
