Early clinical experience with lacosamide as adjunctive therapy in patients with refractory focal epilepsy and nocturnal seizures.

摘要

This retrospective study reports the early experience with lacosamide (LCM) as adjunctive therapy in Spanish patients with refractory focal epilepsy. Sixty patients (mean age 38.3 years, 54% women, mean epilepsy duration 27.2 years, mean seizure rate 9.7/month, and 28% with mainly nocturnal seizures) taking >/=2 antiepileptic drugs (mean 2.2) were included. LCM maintenance doses were 200, 300, 400, and 500mg/day in 31, 16, 10, and 3 patients, respectively. Patients were followed up for 13-24 months. Twenty-eight patients (47%) reported a >/=50% reduction in seizure frequency. A >/=50% reduction in seizure frequency was reported by 65% and 40% of patients in the nocturnal seizure and diurnal seizure subgroups, respectively (p>0.05). Of the 28 responders, 2 achieved stable periods of seizure freedom of 6 and 11 months after starting LCM. Twenty patients (33%) reported drug-related adverse events (AEs); the most common was dizziness (16 patients). LCM was withdrawn in 8 patients (13%). There were no serious AEs. These results support the efficacy and safety of adjunctive LCM in patients with partial-onset seizures.
