Topiramate (CAS 97240-79-4) is an anticonvulsant compound widely investigated for its interactions with multiple neuronal ion channels and neurotransmitter receptors including AMPA kainate and NMDA glutamate receptors as well as GABA A receptors and voltage-gated Na channels In vitro studies demonstrate that at submicromolar concentrations (IC 0 5 M) topiramate selectively inhibits GluR5-containing kainate receptor-mediated excitatory synaptic currents in rat basolateral amygdala neurons and partially attenuates AMPA receptor-mediated responses Electrophysiological assays in cortical slices reveal that topiramate modulates persistent Na currents and shifts steady-state inactivation In animal models topiramate confers dose-dependent neuroprotection in ischemic stroke and elevates seizure thresholds supporting its utility for mechanistic studies of epilepsy and neuroprotection
