This medicine contains quinapril as active ingredient. It belongs to the class of medicines called angiotensin-converting enzyme (ACE) inhibitors. The drug works by relaxing the muscles around blood vessels, allowing them to dilate and thereby easing blood flow.
The ACE inhibitors are powerful vasodilators. They act by blocking the action of an enzyme that is responsible for converting a chemical called angiotensin I into angiotensin II. Angiotensin II encourages constriction of the blood vessels, and the absence permits them to dilate.
The medicine is prescribed for:
- Treatment of high blood pressure and congestive heart failure.
- Treatment for kidney disease in diabetic patients.
- Treatment of acute myocardial infarction within 24 hours of occurrence.
