Description

Topiramate Pharmacodynamics
Antiepileptic drug, belongs to the class of sulfate-substituted monosaccharides.
Topiramate decreases the frequency of action potentials, which are characteristic of the neuron in the state of persistent depolarization, indicating that the drug’s blocking effect on sodium channels depends on the state of the neuron. Topiramate potentiates GABA activity against several GABA-receptor subtypes (including GABAA-receptors) and modulates the activity of GABAA-receptors themselves, prevents kainat activation of kainate/AMPK receptor sensitivity to glutamate, does not affect N-methyl-D-aspartate activity against NMDA-receptors. These effects of topiramate are dose-dependent at plasma concentrations of topiramate between 1 μM and 200 μM, with minimal activity between 1 μM and 10 μM.
In addition, topiramate inhibits the activity of some carboanhydrase isoenzymes, but this effect is weaker in topiramate than in acetazolamide and does not seem to be the main one in the antiepileptic activity of topiramate.
