Abstract

To assess whether levetiracetam elimination is influenced by enzyme inducing antiepileptic drugs (EIAEDs), serum levetiracetam levels were determined at frequent intervals after a single oral 1000. mg dose in 15 subjects co-medicated with EIAEDs and 15 matched controls. The EIAED group showed a higher levetiracetam oral clearance (p=0.01) and a shorter half-life (p=0.02) than controls. Although the magnitude of interaction is relatively modest, it could have clinical significance for some patients.
