Description: Rufinamide is a board spectrum anticonvulsant. It is used in combination with other medication and therapy to treat Lennox–Gastaut syndrome and various other seizure disorders. Rufinamide was approved by the US Food and Drug Administration on November 14, 2008 as adjunctive treatment of seizures associated with Lennox-Gastaut syndrome in children 4 years and older and adults. Rufinamide has efficacy for partial seizures. Rufinamide prolongs the inactivation of sodium channels and limits the frequency of action potential firing in cultured and acutely isolated neurons.
