Purpose: The treatment options for Lennox–Gastaut syndrome (LGS), a pediatric epileptic syndrome, are limited, especially in younger children. Rufinamide tablets were safe and effective as an add-on treatment in Korean children and adolescents <20 years of age with LGS. This subgroup analysis aimed to evaluate the efficacy and safety of rufinamide tablets in LGS pediatric patients aged 1–4 years. Methods: This was a retrospective, observational study in LGS patients aged 1–4 years who received 12 weeks of treatment with rufinamide orally as an adjuvant treatment between April and June 2010. The proportion of responders (patients with a ≥50% reduction in seizure frequency after rufinamide treatment) was evaluated according to the type of seizure. The proportion of patients who were seizure-free was also evaluated. Adverse events (AEs) were evaluated after 12 weeks of treatment. Results: Among the 15 patients evaluated, one discontinued treatment because of worsening seizures 4 weeks after administration of rufinamide. Seven (46.67%) patients were responders and four patients were seizure-free. There were four responders with convulsive seizures, one each for myoclonic seizures and drop attacks, and spasms. The responder rate was increased to 69.23% by long-term treatment of rufinamide. AEs were experienced by three patients. One patient each experienced somnolence, fatigue, and rash. Conclusion: Rufinamide tablets were efficacious and well tolerated in LGS patients aged 1–4 years, at doses up to 1000 mg per day, when given as add-on therapy to other antiepileptic drugs.
