Abstract
BackgroundDespite the introduction of multiple new antiepileptic drugs in the past two decades, many patients with epilepsy continue to experience uncontrolled seizures or significant side effects. AimTo present our experience with felbamate therapy in children with drug-resistant epilepsy. MethodsWe retrospectively reviewed the medical charts and video-EEG recordings of all patients receiving felbamate until May 2012. Efficacy was determined according to seizure frequency during the week prior to treatment initiation and the week after the maximal dosage of felbamate was reached. ResultsFifty patients (34 boys) aged 4 months to 17 years (mean – 5.5 years) were identified. Nearly third of the patients had Lennox–Gastaut syndrome. Mean epilepsy duration was 3.4 years (range – 1 month to 13 years). The mean number of previous antiepileptic drugs was 7.5. The mean duration of follow-up was 1.1 years. Seizure frequency decreased by at least 50% in 29 (58%) patients. Side effects were reported in 22 (44%) patients, none of them included aplastic anemia or liver failure. In the responder group, the maximal dose of felbamate was lower and the patients were older compared to non-responders. ConclusionsDespite current recommendations, felbamate is initiated following multiple AEDs. Based on its efficacy and safety data, earlier initiation of felbamate is recommended in children with refractory epilepsy.
