Lisinopril and [captopril] are the only ACEIs that are not prodrugs. It functions by inhibition of angiotensin converting enzyme as well as the renin angiotensin aldosterone system. ACEIs are commonly used as a first line therapy in the treatment of hypertension, along with thiazide diuretics or beta blockers.  Lisinopril was granted FDA approval on 29 December 1987."}]
