Quinapril was originally developed by Pfizer Pharmaceuticals; but now that it has come off patent, several companies manufacture a generic version of the drug. Sold under the name Quinapril tablets, generic quinapril is available in a number of strengths.
Quinapril hydrochloride (Accupril®) is a prescription medication that has been licensed to treat high blood pressure (hypertension) and congestive heart failure. Quinapril is part of a class of drugs called angiotensin-converting enzyme inhibitors, or ACE inhibitors for short. Quinapril helps to block the angiotensin-converting enzyme, which is normally part of a reaction in the body that causes blood vessels to narrow (constrict). By blocking this enzyme, quinapril causes blood vessels to relax, which lowers blood pressure. It also allows the heart to work more efficiently.
Quinapril was originally developed by Pfizer Pharmaceuticals. It has since come off patent, making it available as a generic.

- Quinapril HCL 5 mg tablets
- Quinapril HCL 10 mg tablets
- Quinapril HCL 20 mg tablets
- Quinapril HCL 40 mg tablets.
