The precise mechanism(s) by which Levetiracetam exerts its antiepileptic effect is unknown. Levetiracetam showed only minimal activity in submaximal stimulation and in threshold tests. Protection was observed, however, against secondarily generalized activity from focal seizures induced by pilocarpine and kainic acid, two chemo convulsants that induce seizures that mimic some features of human complex partial seizures with secondary generalization. In vitro and in vivo recordings of epileptiform activity from the hippocampus have shown that Levetiracetam inhibits burst firing without affecting normal neuronal excitability, suggesting that Levetiracetam may selectively prevent hyper synchronization of epileptiform burst firing and propagation of seizure activity.
