Rufinamide.
Rufinamide is a new antiepileptic drug that is effective in acute animal seizure models and also in the kindling model of epilepsy with a high protective index. Its mechanism of action is largely unknown; studies suggest an effect at voltage-gated sodium channels, but whether this is its main mode of action remains to be determined. Rufinamide can be administered twice daily and has minimal drug interactions (it does, however, interact with the contraceptive pill). Food markedly increases absorption, which may complicate clinical use. Trials indicate that rufinamide is effective as adjunctive therapy in partial epilepsy and the Lennox-Gastaut syndrome with minimal adverse effects including headache, dizziness and fatigue. In addition, rufinamide has a favorable cognitive side-effect profile. However, it remains uncertain whether rufinamide offers significant advantages over other current antiepileptic drugs, and the results of further clinical trials are awaited.
