Identification
- Summary
Quinapril is an ACE inhibitor prodrug used to treat hypertension, congestive heart failure, and slow rate of progression of renal disease.
- Brand Names
- Accupril, Accuretic
- Generic Name
- Quinapril
- DrugBank Accession Number
- DB00881
- Background
Quinapril is the ethyl ester prodrug of the non-sulfhydryl angiotensin converting enzyme inhibitor quinaprilat.6,7 It is used to treat hypertension and heart failure.6,7 ACE inhibitors are commonly used as a first line therapy in the treatment of hypertension, along with thiazide diuretics or beta blockers.5
Quinapril was granted FDA approval on 19 November 1991.6 A combination tablet with hydrochlorothiazide was also approved on 28 December 1999.7

- Contraindications & Blackbox Warnings
Contraindications & Blackbox WarningsWith our commercial data, access important information on dangerous risks, contraindications, and adverse effects.Our Blackbox Warnings cover Risks, Contraindications, and Adverse Effects- Pharmacodynamics
Quinapril is a prodrug of an angiotensin converting enzyme (ACE) inhibitor used in the treatment of hypertension or adjunct in the treatment of heart failure.1,2,6 Quinapril has a wide therapeutic window and a long duration of action as it is given in doses of 10-80mg once daily.6
- Mechanism of action
Angiotensin II constricts coronary blood vessels and is positively inotropic, which under normal circumstances, would increase vascular resistance and oxygen consumption.4 This action can eventually lead to myocyte hypertrophy and vascular smooth muscle cell proliferation.4 Angiotensin II also stimulates production of plasminogen activator inhibitor-1 (PAI-1), increasing the risk of thrombosis.2
Quinaprilat prevents the conversion of angiotensin I to angiotensin II by inhibition of angiotensin converting enzyme, and also reduces the breakdown of bradykinin.1,2 Reduced levels of angiotensin II lead to lower levels of PAI-1, reducing the risk of thrombosis, especially after a myocardial infarction.2
Target Actions Organism AAngiotensin-converting enzyme inhibitorHumans - Absorption
Quinapril if 50-80% bioavailable.1 Quinapril has a Tmax of <1 hour,6 while quinaprilat has a Tmax of 2.5h.1 The Cmax of quinaprilat is highly variable but reaches 1526ng/mL with an AUC of 2443ng*h/mL in healthy males given a 10mg dose.1 A high fat meal reduces the absorption of quinapril by 25-30%.1
- Volume of distribution
The mean volume of distribution of quinaprilat is 13.9L.1
- Protein binding
Quinapril and the active metabolite quinaprilat are 97% protein bound in plasma.6,7
- Metabolism
Quinapril is de-esterified to the active quinaprilat or dehydrated to form the inactive PD109488.1,3 PD109488 can undergo O-deethylation to form another inactive metabolite, PD113413.1,3
Hover over products below to view reaction partners
- Route of elimination
Quinaprilat is up to 96% eliminated in the urine.6 The eliminated metabolites PD109488 and PD113413 account for approximately 6% of a dose of quinapril each.1,3 A small fraction of the dose recovered in the urine is accounted for by unmetabolized quinapril.3
- Half-life
The active metabolite quinaprilat has an elimination half life of 2.3 hours.1,6
- Clearance
The clearance of quinaprilat is 68mL/min.1
- Adverse Effects

The oral LD50 in rats is 3541mg/kg and in mice is 1739mg/kg.8
Patients experiencing an overdose may present with symptoms of severe hypotension.6,7 Due to the extensive protein binding of quinapril and the active metabolite quinaprilat, hemodialysis is not expected to remove the drug from circulation.6,7 Treat patients with symptomatic and supportive measures, including normal saline infusions to restore normal blood pressure.6,7

- Avoid fatty foods.
- Avoid hypertensive herbs (e.g. bayberry, blue cohosh, cayenne, ephedra, and licorice).
- Avoid potassium-containing products. Potassium products increase the risk of hyperkalemia.
- Limit salt intake. Salt may attenuate the antihypertensive effect.
