Application

Quinapril hydrochloride has been used as an angiotensin-converting enzyme (ACE) inhibitor to study its effects on renal tubular epithelial cell proliferation in human renal tubular epithelial cells. It has also been used as an ACE inhibitor to evaluate its effects on the expression of angiotensin II (AII) in patient-derived Atheroma samples.

Biochem/physiol Actions

Quinapril has been studied to exhibit therapeutic effects against hypertension and congestive heart failure.
Quinapril is a short-acting angiotensin converting enzyme (ACE) inhibitor.

Quinapril is rapidly de-esterified after absorption to quinaprilat (the active diacid metabolite), a potent angiotensin converting enzyme (ACE) inhibitor. Quinapril produces favourable haemodynamic changes, and improves ventricular and endothelial function in patients with various cardiovascular disorders; these effects are mediated

Following systemic absorption, quinapril is converted by de-esterification to quinaprilat (the active diacid metabolite), an inhibitor of angiotensin converting enzyme (ACE). Pharmacodynamic studies in animals indicate inhibition of ACE both in plasma and at tissue sites, such as the arterial
