Lisinopril is a long-acting inhibitor of angiotensin converting enzyme (ACE) with IC50 value of 4.7nM [1].
Lisinopril is a lysine analogue of MK 421. Both of them are the inhibitors of ACE and found to significantly inhibit the pressor response to exogenous angiotensin I. The administration of lisinopril can lower the diastolic and systolic blood pressure and higher the heart rate. Lisinopril is found to reduce the activity of plasma angiotensin converting enzyme markedly. It increases the level of plasma rennin while decreases the levels of plasma Angiotensin II and aldosterone. Lisinopril is a drug now used for many disorders including hypertension, heart failure, acute myocardial infarction and diabetic nephropathy. lisinopril dehydrate is the commercial form of this drug [2, 3].
