Historical note and terminology

Levetiracetam is a pyrrolidone derivative and not related to any of the antiepileptic drugs currently in use. It has been approved by the Food and Drug Administration in the United States and in the European Union and various other countries. Although levetiracetam is more expensive than traditional antiepileptic drugs, its cost is comparable to that of newer antiepileptic drugs.
