Benazepril hydrochloride (HCl), USP is a white to off-white
crystalline powder, soluble (>100 mg/mL)
in water, in ethanol, and in methanol. Its chemical name is benazepril
3-[[1-(ethoxy-carbonyl)-3-phenyl-
(1S)-propyl]amino]-2,3,4,5-tetrahydro-2-oxo-1H-1-(3S)-benzazepine-1-acetic
acid monohydrochloride;
its structural formula is
Its empirical formula is C24H28N2O5•HCl, and its molecular weight is
460.96.
Benazeprilat, the active metabolite of benazepril, is a non-sulfhydryl
angiotensin-converting enzyme
inhibitor. Benazepril is converted to benazeprilat by hepatic cleavage
of the ester group.

tablets containing either 5 mg, 10
mg, 20 mg, or 40 mg of benazepril HCl, USP for oral administration.

CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
Benazepril and benazeprilat inhibit angiotensin-converting enzyme
(ACE) in human subjects and animals.
ACE is a peptidyl dipeptidase that catalyzes the conversion of
angiotensin I to the vasoconstrictor
substance, angiotensin II. Angiotensin II also stimulates aldosterone
secretion by the adrenal cortex.
Inhibition of ACE results in decreased plasma angiotensin II, which
leads to decreased vasopressor
activity and to decreased aldosterone secretion. The latter decrease
may result in a small increase of
serum potassium. Hypertensive patients treated with benazepril HCl
alone for up to 52 weeks had
elevations of serum potassium of up to 0.2 mEq/L. Similar patients
treated with benaze
