Widely used in the pharmaceutical industry as an active pharmaceutical ingredient (API) in antihypertensive medications. It functions as an angiotensin-converting enzyme (ACE) inhibitor, helping to relax blood vessels and lower blood pressure. Commonly prescribed for the treatment of hypertension and heart failure, it also reduces the risk of stroke and myocardial infarction in high-risk patients. Additionally, it is used in managing diabetic nephropathy due to its protective effects on kidney function in diabetic individuals. Its mechanism involves blocking the conversion of angiotensin I to angiotensin II, a potent vasoconstrictor, thereby decreasing systemic vascular resistance.
