Micardis HCT

1 What is Micardis HCT?

Brand: Micardis HCT

Generic: Telmisartan and Hydrochlorothiazide

Micardis HCT is used in treating hypertension or high blood pressure. High blood pressure brings more work to the heart and arteries.

When left untreated, the heart and arteries may stop functioning well. This can result in damage to the blood vessels of the heart, brain, and kidneys, which may cause a stroke, kidney failure, or heart failure. By lowering blood pressure, the risk of strokes and heart attacks are decreased.

Telmisartan is an ARB or angiotensin II receptor blocker, which works by blocking a substance in the body that tightens the blood vessels.

This results in relaxed blood vessels, eventually lowering the blood pressure and increasing the supply of oxygen and blood to the heart.

Hydrochlorothiazide is a thiazide diuretic that reduces the amount of water in the body through increased urine output. This helps in lowering the blood pressure. Telmisartan and hydrochlorothiazide combination is only available with a prescription.
