DESCRIPTION
Chemically, meclizinehydrochloride, USP is
1-(p-chloro-α-phenylbenzyl)-4-(m-
methylbenzyl) piperazine dihydrochloride monohydrate.
Inactive ingredients for the tablets are: colloidal silicon dioxide,
lactose monohydrate,
magnesium stearate, microcrystalline cellulose, sodium starch
glycolate and talc. The
12.5 mg tablets also contain FD&C Blue #1 Aluminum Lake. The 25 mg
tablets also
contain D&C Yellow #10 Aluminum Lake.
CLINICAL PHARMACOLOGY
Meclizine hydrochloride is an antihistamine that shows marked
protective activity against
nebulized histamine and lethal doses of intravenously injected
histamine in guinea pigs. It
has a marked effect in blocking the vasodepressor response to
histamine, but only a
slight blocking action against acetylcholine. Its activity is
relatively weak in inhibiting the
spasmogenic action of histamine on isolated guinea pig ileum.
PHARMACOKINETICS
The available pharmacokinetic information for meclizine following oral
administration has
been summarized from published literature.
ABSORPTION
Meclizine is absorbed after oral administration with maximum plasma
concentrations
reaching at a median T
value of 3 hours post-dose (range: 1.5 to 6 hours) for the
tablet dosage form.
DISTRIBUTION
Drug distribution characteristics for meclizine in humans are unknown.
METABOLISM
The metabolic fate of meclizine in humans is unknown. In an in vitro
metabolic study
using human hepatic microsome and recombinant CYP enzyme, CYP2D6 was
found to
max
be the dominant enzyme for metabolism of meclizine.
The genetic polymorphism of CYP2D6 that results in extensive-, poor-,
intermediate-and
ultrarapid metabolizer phenotypes could contribute to large
inter-individual variability in
meclizine exposure.
ELIMINATION
Meclizine has a plasma elimination half-life of about 5 to 6 hours in
humans.
INDICATIONS AND USAGE
Meclizine hydrochloride tablets are indicated for the treatment of
vertigo associated wit
