An angiotensin-converting-enzyme inhibitor (ACE inhibitor) is a pharmaceutical drug used primarily for the treatment of hypertension (elevated blood pressure) and congestive heart failure.
Renin converts angiotensinogen, a proenzyme synthesized in the liver, into the decapeptide angiotensin I, which is then converted in the lungs into the octapeptide angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II is both a stimulator of aldosterone secretion and a potent vasopressor.
