CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
The precise mechanism(s) by which levetiracetam exerts its
antiepileptic effect is unknown. The
antiepileptic activity of levetiracetam was assessed in a number of
animal models of epileptic seizures.
Levetiracetam did not inhibit single seizures induced by maximal
stimulation with electrical current or
different chemoconvulsants and 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 chemoconvulsants that
induce seizures that mimic some
features of human complex partial seizures with secondary
generalization. Levetiracetam also displayed
inhibitory properties in the kindling model in rats, another model of
human complex partial seizures,
both during kindling development and in the fully kindled state. The
