Topiramate (Topamax)
(toh- PYRE-ah-mayt)
Pregnancy Category: C Topamax (Rx)

Classification: Anticonvulsant, miscellaneous

See Also: See also Anticonvulsants.

Action/Kinetics: Precise mechanism not known. The following effects may contribute to the anticonvulsant activity. (1) Action potentials seen repetitively by sustained depolarization of neurons are blocked in a time-dependent manner, suggesting an effect to block sodium channels. (2) Increases the frequency at which GABA activates GABA A receptors, thus enhancing the ability of GABA to cause a flux of chloride ions into neurons (i.e., enhanced effect of the inhibitory transmitter, GABA A). (3) Antagonizes the ability of kainate to activate the kainate/AMPA subtype of excitatory amino acid aspartate, thus reducing the excitatory effect. Rapidly absorbed; peak plasma levels: About 2 hr. t 1/2, elimination: 21 hr. Steady state is reached in about 4 days in those with normal renal function. Excreted mostly unchanged in the urine.
