title: Therapeutic interaction of lamotrigine and sodium valproate in intractable myoclonic epilepsy.
abstract: The clinical and EEG features of a 13-year-old girl with an unusual refractory myoclonic epilepsy is presented. Control was achieved only when lamotrigine was combined with sodium valproate. This may represent a specific pharmacodynamic interaction between these drugs with implications for therapy in the generalized epilepsies.
