Primarily used in the treatment of high blood pressure (hypertension), it helps to relax blood vessels, allowing blood to flow more smoothly and the heart to pump more efficiently. It is also prescribed for managing heart failure and improving survival after a heart attack. By inhibiting the angiotensin-converting enzyme (ACE), it reduces the production of angiotensin II, a substance that narrows blood vessels and releases hormones that can elevate blood pressure. This medication is often part of a comprehensive treatment plan that includes diet, exercise, and other medications. It is crucial to follow the prescribed dosage and consult a healthcare provider for any adjustments or concerns.
