title: Rufinamide for the treatment of Lennox-Gastaut syndrome.
abstract: BACKGROUND
  Lennox-Gastaut syndrome (LGS) is a severe treatment-resistant childhood-onset epilepsy. This review examines the role of the new drug rufinamide for the treatment of LGS.
  
  
  METHODS
  MEDLINE and Google Scholar searches were undertaken. The pharmaceutical company was contacted for the latest information. LGS is characterized by the triad of diffuse slow spike-wave discharges in the electroencephalogram (EEG), learning disability (mental retardation) and frequent generalized seizures of multiple types, usually including tonic, atonic and atypical absence seizures. Felbamate, lamotrigine and topiramate have resulted in significant reductions in some seizure types, but no treatment has achieved acceptable seizure control in most patients. In a pivotal randomized, double-blind, placebo-controlled trial, the new drug rufinamide achieved significant improvements in seizure control in previously resistant subjects when added to up to three concomitant antiepileptic drugs. Open studies including patients with LGS have also demonstrated efficacy. These trials and a large open trial in adults and adolescents with partial seizures have revealed no serious adverse effects so far. The most common adverse events were fatigue/somnolence and vomiting. Rufinamide is of value in decreasing seizure frequency in LGS, but seizure freedom is seldom achieved. Although no serious adverse effects have been identified, the limited data available at present allow no firm conclusions to be drawn with regard to safety.
  
  
  CONCLUSIONS
  The data support a role for rufinamide in treating LGS. However, more efforts are required to provide antiepileptic drugs for this treatment-resistant epilepsy syndrome. Rufinamide might also be of value in treating other forms of epilepsy.
