Some people may ask, "What is losartan-hydrochlorothiazide used for?" Losartan-hydrochlorothiazide is used to lower high blood pressure in adults. Because losartan-hydrochlorothiazide is made up of two medications -- Cozaar and hydrochlorothiazide -- it not only relaxes the blood vessels, but also allows the kidneys to remove more salt and water from the blood. As a result, this helps lower blood pressure, as well as decrease the risks that occur with long-term high blood pressure.
Based on clinical studies, losartan-hydrochlorothiazide has been shown to significantly lower systolic and diastolic blood pressure. The higher the dose of losartan-hydrochlorothiazide, the greater the drop in blood pressure tended to be. By lowering blood pressure, losartan-hydrochlorothiazide can decrease the risks that occur with long-term high blood pressure (see Effects of High Blood Pressure). However, losartan-hydrochlorothiazide is not a cure for high blood pressure.
