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. By relaxing blood vessels, it improves blood flow and decreases the workload on the heart. Commonly prescribed for patients with heart failure or those who have had a heart attack, it supports long-term cardiovascular protection by reducing the risk of heart attacks, strokes, and kidney problems in people with diabetes or existing vascular damage. It is often part of long-term management strategies in patients with chronic cardiovascular conditions and may be combined with other medications such as diuretics or calcium channel blockers for enhanced effect.
