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.
