title: Effects of remacemide in two models of genetically determined generalized epilepsy, the GAERS and the audiogenic Wistar AS.
abstract: The antiepileptic effects of remacemide were assessed in two models of genetically determined generalized epilepsy. The model of non-convulsive epilepsy used was a model of absence seizures, the GAERS (genetic absence epilepsy rats from Strasbourg), and the model of convulsive seizures was an audiogenic rat model, the Wistar AS. In the eight GAERS studied, the three doses of remacemide (20, 40, and 80 mg/kg) dose-dependently reduced the expression of spike-and-wave discharges (SWDs) that had almost totally disappeared at the highest dose used, 80 mg/kg. However, at the latter dose, the effect of remacemide may be partly due to a change in the vigilance level of the animals. In the Wistar AS, the dose of 20 mg/kg prolonged by twofold the latencies to wild running and tonic seizures, and prevented their expression in one rat out of the eight studied. At 40 mg/kg, the expression of wild running and tonic seizures was inhibited in seven and maintained in one of the eight rats studied. The present results support the effects of remacemide in tonic/clonic seizure, which was the first target of the drug, and confirm the effect of the anticonvulsant on absence seizures.
