Levetiracetam: treatment in epilepsy

A large number of new antiepileptic drugs (AEDs) have become available over the last 10 years. Results from placebo-controlled clinical trials and community-based practice have demonstrated that levetiracetam has a broad spectrum of activity in suppressing seizures as add-on treatment and monotherapy and that it is safe and well-tolerated. Levetiracetam also has a favourable pharmacokinetic profile characterised by rapid and nearly complete absorption, very low potential for drug interactions and a prolonged pharmacodynamic effect that permits twice-daily dosing. Although, the mechanism of action of levetiracetam is not completely understood, preclinical studies suggest that it may have antiepileptogenic and neuroprotective effects, with the potential to slow or arrest disease progression.
