INITIAL U.S. APPROVAL:
DESCRIPTION
Verapamil hydrochloride (verapamil HCl) is a calcium ion influx
inhibitor (slow-channel blocker or
calcium ion antagonist) available for oral administration in
film-coated tablets containing 80 mg of
verapamil hydrochloride.
The structural formula of verapamil HCl is:
C27H38N2O4• HCl M.W. = 491.08
Benzeneacetonitrile, a-[3-[[2-(3,4-dimethoxyphenyl)ethyl]
methylamino]propyl]-3,4-dimethoxy-a-(1-
methylethyl) hydrochloride
Verapamil HCl is an almost white, crystalline powder, practically free
of odor, with a bitter taste. It is
soluble in water, chloroform, and methanol. Verapamil HCl is not
chemically related to other
cardioactive drugs.
Inactive ingredients include colloidal silicon dioxide, dibasic
calcium phosphate dihydrate, magnesium
stearate, microcrystalline cellulose, sodium starch glycolate, light
mineral oil, sodium lauryl sulfate,
titanium dioxide and hypromellose.
CLINICAL PHARMACOLOGY
Verapamil hydrochloride is a calcium ion influx inhibitor
(slow-channel blocker or calcium ion
antagonist) that exerts its pharmacologic effects by modulating the
influx of ionic calcium across the
cell membrane of the arterial smooth muscle as well as in conductile
and contractile myocardial cells.
MECHANISM OF ACTION
Angina: The precise mechanism of action of verapamil hydrochloride as
an antianginal agent remains to
be fully determined, but includes the following two mechanisms:
ARRHYTHMIA: Electrical activity through the AV node depends, to a
significant degree, upon calcium
influx through the slow channel. By decreasing the influx of calcium,
verapamil hydrochloride
prolongs the effective refractory per
