Valsartan HCTZ

Valsartan HCTZ

Descriptions of Valsartan HCTZ

Valsartan and hydrochlorothiazide combination is used alone or with other medicines 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 can reduce the risk of strokes and heart attacks.


This drug is used to treat high blood pressure. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. This product contains two medications: valsartan and hydrochlorothiazide. Valsartan is an angiotensin receptor blocker (ARB) and works by relaxing blood vessels so that blood can flow more easily. Hydrochlorothiazide is a "water pill" (diuretic) that causes you to make more urine, which helps your body get rid of extra salt and water.

How it works

Valsartan belongs to a class of drugs called angiotensin II receptor blockers. Hydrochlorothiazide belongs to a class of drugs called diuretics. A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Valsartan blocks the action of angiotensin II, a chemical in your body that causes blood vessels to tighten and narrow. This helps to relax and widen your blood vessels, which lowers your blood pressure.

Hydrochlorothiazide may work by removing sodium (salt) and water from your body. This helps reduce your blood pressure.
