Serum levetiracetam concentrations and adverse events after multiple dose extended release levetiracetam administration to healthy cats.

Background: Multiple dose administration of antiepileptic drugs to cats presents a challenge for owners. Extended release levetiracetam (XRL) has once daily recommended dosing interval, but multiple dose administration of XRL has not been evaluated in cats.

Objective: Evaluate serum levetiracetam concentrations and adverse clinical effects after 11 days of once daily XRL administration to healthy cats.
