title: [Safety of levetiracetam as adjunctive therapy in epilepsy: the SKATE trial in Spain].
abstract: OBJECTIVE
  To continue assessing safety and to evaluate the efficacy of levetiracetam and to assess the optimal dose in community based practice.
  
  
  METHODS
  Single-arm, open label, multicenter, observational and prospective trial lasting 16-22 weeks. Criteria for inclusion: patients > 16 years experiencing epilepsy with partial seizures taking at least one concomitant antiepileptic drug. The initial dose was 1,000 mg/day, up to the maximal dose of 3,000 mg/day. Safety evaluation was adverse events reporting. Efficacy evaluation were reduction in seizure frequency; QOLIE-10 questionnaire and global evaluation scale of disease severity.
  
  
  RESULTS
  Of the 342 subjects, 296 (86.5%) completed the treatment period. 103 subjects (30.1%) experienced at least one adverse event. The most frequently adverse events reported were somnolence (11.7%), dizziness (5.8%) and headache (3.5%). The events were majority (93.1%) of mild to moderate intensity. The median percent reduction in partial seizure frequency per week was 55%. 51.2% of patients experienced a reduction 50% in partial seizure frequency. Similar results were observed for total seizures. An increase of QOLIE-10 total score was observed (10.2 +/- 17.8). A total of 63.5% patients were rated as having moderate or marked improvement in their disease severity.
  
  
  CONCLUSIONS
  These data confirm and provide additional support of levetiracetam safety and efficacy demonstrated in phase III trials.
