Benazepril; Hydrochlorothiazide, HCTZ tablets
What are benazepril; hydrochlorothiazide tablets?
BENAZEPRIL-HYDROCHLOROTHIAZIDE (Lotensin® HCT) is a combination of two drugs used to lower blood pressure. Benazepril is an ACE inhibitor that controls high blood pressure (hypertension) by relaxing blood vessels. Hydrochlorothiazide is a diuretic. High blood pressure can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. By lowering blood pressure, benazepril-hydrochlorothiazide can help reduce your risk of having damage to your kidneys, heart, or other organs. This medicine does not cure high blood pressure. Generic benazepril-hydrochlorothiazide tablets are available.
