Osartan-HZ combines Losartan Potassium (50 mg) and Hydrochlorothiazide (12.5 mg) in a single tablet to provide powerful and balanced management of hypertension. Losartan, an angiotensin II receptor blocker (ARB), helps relax blood vessels, while hydrochlorothiazide, a thiazide diuretic, reduces excess fluid by promoting urine production. Together, they work synergistically to lower high blood pressure and reduce the risk of complications like stroke and heart disease.
