Candesartan and hydrochlorothiazide

Generic name: Candesartan And Hydrochlorothiazide
Drug class: Angiotensin II inhibitors with thiazides

Usage of Candesartan and hydrochlorothiazide

Candesartan and Hydrochlorothiazide combination is used to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure reduces the risk of stroke and heart attack.

Candesartan is an angiotensin II receptor blocker (ARB). It works by blocking the action of a substance in the body that causes the blood vessels to tighten. As a result, candesartan relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.

Hydrochlorothiazide is a thiazide diuretic (water pill). It reduces the amount of water in the body by increasing the flow of urine, which helps lower the blood pressure.

This medicine is available only with your doctor's prescription.
