The available pharmacokinetic information for Meclizine following oral administration tab been summarized from published literature. Absorption Meclizine is absorbed after oral administration with maximum plasma concentrations reaching at a median Tmax value of 3 hours post-dose range: 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 meclizine and recombinant CYP enzyme, CYP2D6 was found to be the dominant enzyme for metabolism 12.5mg 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, meclizine tab 12.5mg.
