Used primarily in the treatment of hypertension (high blood pressure), this compound helps lower blood pressure by inhibiting the angiotensin-converting enzyme (ACE), which reduces the production of angiotensin II—a substance that narrows blood vessels. As a result, blood vessels relax and widen, improving blood flow. It is also prescribed for heart failure and to improve survival after heart attacks, particularly in patients with signs of heart failure. Additionally, it can help protect kidney function in patients with diabetes by reducing proteinuria and slowing the progression of kidney damage. Its action makes it a key medication in managing cardiovascular and renal conditions.
