title: Progabide for refractory partial epilepsy: a controlled add-on trial.
abstract: Progabide, an experimental GABA-ergic antiepileptic drug, was given in a placebo-controlled double-blind cross-over trial to 19 adult patients with chronic partial epilepsy refractory to previous high-dose antiepileptic drug therapy. A mean daily dose of 32 mg/kg (range, 16 to 63) of progabide did not significantly change the seizure frequency. In patients with a therapeutic response, progabide led to an increase in the plasma concentration of phenytoin and phenobarbital. Comedication with carbamazepine was associated with a poor response to progabide. Side effects were mild except for a several-fold increase of SGOT and SGPT, which required withdrawal of progabide in one patient. Progabide does not seem to be the drug urgently needed for failures of previous high-dose drug therapy.
