[Neuroprotective effects of topiramate].

Topiramate (TPM) is a new anti-convulsant drug, prescribed in epileptic seizure. Pharmacological actions of TPM are: a) a positive modulation of GABA receptors; b) inhibition of the kainite and aminohydroxymethylisoxazole propionic acid (AMPA) glutamate receptor sub-types; c) a use-dependent Na+ channel blocker. Recent studies suggest that TPM can have anti-excitotoxic properties, because it protects against motor neuron degeneration. Moreover, TPM enhances neuroprotection and reduces hemorrhagic incidence in focal cerebral ischemia.
