Lisinopril-HCTZ (generic Zestoretic) is a prescription medication generally used to treat high blood pressure. Lisinopril-HCTZ is a combination of the prescription drugs lisinopril and hydrochlorothiazide in a single form. Lisinopril belongs to a class of medications called ACE inhibitors, which decrease certain chemicals that tighten blood vessels. Hydrochlorothiazide is a thiazide diuretic (sometimes called a “water pill”) that helps to rid the body of excess water and salt.
Lisinopril-HCTZ is used alongside healthy lifestyle changes (such as a diet low in fat and salt, regular exercise, maintaining a healthy weight, and abstaining from smoking and alcohol) to treat high blood pressure (hypertension).
