Quinapril (quinapril) — Uses, Dosage, Side Effects & Safety
Drug class: Angiotensin-Converting Enzyme (ACE) Inhibitor
Overview
Quinapril is a prescription medication used to treat high blood pressure (hypertension) and heart failure. By lowering blood pressure, it helps reduce the risk of strokes, heart attacks, and kidney problems. Quinapril belongs to a group of medicines called ACE inhibitors. It works by relaxing blood vessels, making it easier for your heart to pump blood throughout your body. Most people take quinapril once or twice daily, with or without food. It is important to take this medication exactly as prescribed, even if you feel well, as high blood pressure often has no symptoms. Do not stop taking quinapril without consulting your healthcare provider.
