Abstract

INTRODUCTION:

Lamotrigine is licensed in many countries for use in patients with partial seizures. Evidence suggests that it may also be effective in generalised epilepsies.

MATERIAL & METHODS:

We analysed retrospectively our patients with idiopathic generalised epilepsy with refractory absences.

RESULTS:

Fifteen patients with idiopathic generalised epilepsies were identified who had been treated with lamotrigine for 3 months or more. All patients were also treated with sodium valproate. Fourteen patients had active absences. Nine (64%) had a total or virtual cessation of absences and in a further patient they became milder and less frequent. One patient reported an increase in seizures. The effective dose of lamotrigine was 1.6-3.0 mg/kg/day in children and 25-50 mg/day in adults. Patients who responded did so after the first or second dose. Lamotrigine was well tolerated.

CONCLUSION:

Low-dose lamotrigine added to sodium valproate appears to be effective in typical absence seizures. A therapeutic interaction of the two drugs seems likely.
