INNOZIDE is a combination medication used primarily for the treatment of high blood pressure (hypertension). It contains two active ingredients: hydrochlorothiazide and enalapril. Hydrochlorothiazide is a type of medicine known as a thiazide diuretic, which helps to prevent your body from absorbing too much salt, leading to a reduction in water retention. Enalapril, on the other hand, belongs to a class of drugs known as ACE inhibitors. It works by relaxing blood vessels, making it easier for the heart to pump blood around the body. Together, these components help to lower blood pressure and reduce the risk of complications associated with hypertension, such as stroke and heart attack. INNOZIDE is typically prescribed when a single medication is not sufficient to control blood pressure.
