Hydrochlorothiazide and Losartan

Hydrochlorothiazide and losartan is a combination medication used to treat high blood pressure (hypertension). This combination drug contains two active ingredients: hydrochlorothiazide, a diuretic that helps to remove excess water and sodium from the body, and losartan, an angiotensin II receptor blocker (ARB) that helps relax blood vessels.
