Quinapril is the generic form of the brand-name medicine Accupril, which is used to treat high blood pressure and heart failure.

Lowering your blood pressure can reduce your risk of having a heart attack, a stroke, or another heart complication.

This prescription medicine belongs to a class of drugs called angiotensin-converting enzyme (ACE) inhibitors. It works by helping to relax your arteries.

The U.S. Food and Drug Administration (FDA) approved quinapril in 1991. It's marketed as Accupril by Pfizer.

Quinapril FAQ

Q: Can I split quinapril tablets in half or should I continue taking the full dosage to lower my blood pressure? Sometimes my blood pressure drops too low.

A: Accupril (quinapril) is a medication that can be used for blood pressure. It is already to split Accupril tablets and the tablets come in several different doses. Please see the following Everyday Health link for more information on quinapril (Accupril). //www.everydayhealth.com/drugs/quinapril It is important to contact your health care provider about any problems you may be having with your medications. If your blood pressure is too low on your current medications your provider may have you decrease the strength of one of your medications or he/she may take you off of one medication completely. It would be helpful to check your blood pressure at various times of the day and write the readings down to show to your provider so they will have several numbers to go off of rather than just the reading you get in the office.
