Therapeutic indications:

Hypertension Quinapril tablets, USP are indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with quinapril tablets, USP. Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, D

DESCRIPTION
Quinapril hydrochloride is the hydrochloride salt of quinapril, the
ethyl ester of a non-sulfhydryl,
angiotensin-converting enzyme (ACE) inhibitor, quinaprilat.
Quinapril hydrochloride is chemically described as [3S-[2[R*(R*)],
3R*]]-2-[2-[[1-(ethoxycarbonyl)-3-
phenylpropyl]amino]-1-oxopropyl]-1,2,3,4-tetrahydro-3-isoquinolinecarboxylic
acid,
monohydrochloride. Its molecular formula is C
H N O •HCl and its structural formula is:

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Quinapril is deesterified to the principal metabolite, quinaprilat,
which is an inhibitor of ACE activity in
human subjects and animals. ACE is a peptidyl dipeptidase that
catalyzes the conversion of angiotensin I
to the vasoconstrictor, angiotensin II. The effect of quinapril in
hypertension and in congestive heart
failure (CHF) appears to result primarily from the inhibition of
circulating and tissue ACE activity,

thereby reducing angiotensin II formation. Quinapril inhibits the
elevation in blood pressure caused by
intravenously administered angiotensin I, but has no effect on the
pressor response to angiotensin II,
norepinephrine or epinephrine. Angiotensin II also stimulates the
secretion of aldost
