croscarmellose sodium and
magnesium stearate. The 12.5 mg tablet also contains FD&C Blue #1
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.
ABS ORPTION
Meclizine is absorbed after oral administration with maximum plasma
concentrations reaching at a
median Tmax value of 3 hours post-dose (range: 1.5 to 6 hours) for the
tablet dosage form.
DIS TRIBUTION
Drug distribution characteristics for meclizine in humans are unknown.
METABOLIS M
The metabolic fate of meclizine in humans is unknown. In an in vitro
metabolic study using human
hepatic microsome and recombinant CYP enzyme, CYP 2D6 was found to be
the dominant enzyme for
25
27
2
2
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 5-6 hours in
humans.
