Hyzaar is primarily used to treat high blood pressure by lowering it to prevent complications associated with it, such as heart attacks and strokes. It is also sometimes used to protect the kidneys in patients with type 2 diabetes who suffer from kidney problems. The drug consists of a combination of two active ingredients: losartan, which belongs to the class of angiotensin II receptor antagonists, and hydrochlorothiazide, which is considered a diuretic.
Hyzaar works by dilating blood vessels and reducing fluid retention in the body, which helps improve blood circulation and control blood pressure.
