Quinapril is an orally active, non-peptide, and non-thiol angiotensin-converting enzyme (ACE) inhibitor. It primarily blocks the conversion of angiotensin I to angiotensin II in both plasma and tissues. Upon enzymatic hydrolysis, Quinapril is converted into the pharmacologically active Quinaprilat and is effective in hypertension models.

Quinapril hydrochloride (PD-109452-2) is an angiotensin-converting enzyme (ACE) inhibitor used in the therapy of hypertension and congestive heart failure. Quinapril hydrochloride is associated with a low rate of transient serum aminotransferase elevations, but has yet to be linked to instances of acute liver injury.

Quinapril-d5 is intended for use as an internal standard for the quantification of quinapril by GC- or LC-MS. Quinapril is a prodrug form of the angiotensin converting enzyme (ACE) inhibitor quinaprilat. In vivo, quinapril reduces mean arterial pressure in renal hypertensive and spontaneously hypertensive rats. It inhibits angiotensin I-induced pressor responses in normotensive rats and dogs. Quinapril prevents left ventricular heart failure in CHF 14.6 cardiomyopathic hamsters. Formulations containing quinapril have been used in the treatment of hypertension, heart failure, and diabetic nephropathy.
