Efficacy and safety of levetiracetam as adjunctive therapy in adult patients with uncontrolled partial epilepsy: the Asia SKATE II Study.

This study evaluated the safety and efficacy of levetiracetam as adjunctive therapy for partial seizures in everyday clinical practice in Asian populations. Patients aged > or =16 years (N=251) with inadequately controlled partial epilepsy were recruited from 29 centers across Asia. Levetiracetam was added to existing antiepileptic medication for 16 weeks at a starting dose of 500 or 1000 mg/day and titrated to a maximum of 3000 mg/day according to clinical response. The study completion rate was 86.9%. Adverse events were reported by 73.3% of patients and were generally mild, leading to treatment withdrawal in only 7.2%. The most common adverse events were somnolence (30.3%) and dizziness (14.7%). Compared with pretreatment baseline, 44.0% of patients had a > or =50% reduction in seizure frequency, with a median reduction of 46.4%, and 17.7% became seizure free during the treatment period. Levetiracetam was well tolerated and efficacious as adjunctive therapy for partial epilepsy in clinical practice among Asian populations. Copyright (c) 2010 Elsevier Inc. All rights reserved.
