FDA Approves Merck's Hyzaar to Lower Hypertension

Hyzaar is a combination of losartan and hydrochlorothiazide prescribed to treat patients with high blood pressure.

It is in a class of medications called angiotensin II receptor antagonists. The losartan component of Hyzaar works by blocking certain chemicals in the body that cause blood vessels to tighten, allowing blood to flow more smoothly. Hydrochlorothiazide functions by reducing the amount of salt and water in the body allowing the kidneys to increase the flow of urine.

Hyzaar contains a combination of hydrochlorothiazide and losartan. Hydrochlorothiazide is a thiazide diuretic (water pill) that helps prevent your body from absorbing too much salt, which can cause fluid retention.

Losartan is a angiotensin II receptor antagonist. Losartan keeps blood vessels from narrowing, which lowers blood pressure and improves blood flow.

Hyzaar is used to treat high blood pressure (hypertension). It is also used to lower the risk of stroke in certain people with heart disease.

Hyzaar is a combination drug used to treat high blood pressure. It consists of losartan, which belongs to the class of angiotensin II receptor blockers, and hydrochlorothiozide, which is a diuretic. Hyzaar is also used to reduce the risk of stroke in patients with high blood pressure and left ventricular hypertrophy (thickening of the heart muscle).

Hyzaar is a combination medication used in the treatment of high blood pressure. One component, losartan, belongs to a new class of blood pressure medications that work by preventing the hormone angiotensin II from constricting the blood vessels, thus allowing blood to flow more freely and keeping the blood pressure down. The other component, hydrochlorothiazide, is a diuretic that increases the output of urine, removing excess fluid from the body and thus lowering blood pressure.
