Talampanel, a potent and selective alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate (AMPA)-receptor antagonist, is a potential new antiepileptic drug (AED). Talampanel dosing strategies may be reliant on concomitant AED medication, as enzyme-inducing AEDs enhance, whereas VPA inhibits its metabolism. Talampanel was well tolerated, although adverse events occurred at lower doses compared with those in healthy subjects, probably because of the additive effect of concomitant AEDs.

Talampanel is a potent noncompetitive and selective antagonist of the glutamine AMPA receptors. Studies in primates have shown that the administration of talampanel to parkinsonian monkeys significantly decreased levodopa-induced dyskinesias by 40%. When given alone, talampanel did not modify the severity of parkinsonian symptoms. However, in combination with levodopa, talampanel potentiated the antiparkinsonian action of levodopa by increasing motor activity.
