Uses For Accupril
Quinapril is used alone or together with other medicines to treat high blood pressure (hypertension). High blood pressure adds to the workload of the heart and arteries. If it continues for a long time, the heart and arteries may not function properly. This can damage the blood vessels of the brain, heart, and kidneys, resulting in a stroke, heart failure, or kidney failure. Lowering blood pressure can reduce the risk of stroke and heart attacks.
Quinapril is an angiotensin converting enzyme (ACE) inhibitor. It works by blocking a substance in the body that causes blood vessels to tighten. As a result, quinapril relaxes the blood vessels. This lowers blood pressure and increases the supply of blood and oxygen to the heart.
Quinapril is also used to treat heart failure or may be used for other conditions as determined by your doctor.
This medicine is available only with your doctor's prescription.
