EFFECTS OF LORECLEZOLE ON EPILEPTIC ACTIVITY AND ON EEG AND BEHAVIOR IN RATS WITH ABSENCE SEIZURES

The antiepileptic profile of loreclezole, a new putative antiepileptic compound, has been determined in rats of the WAG/Rij strain, a genetic model of generalized absence epilepsy. In addition, the effects of 0, 5, 10 and 20 mg/kg loreclezole on the spectral content of the background EEG and on spontaneous behaviour of rats were investigated. Both the number of spike-wave discharges and their total duration dose-dependently decreased following administration of loreclezole. Furthermore, the behaviour of the animals was not markedly influenced and significant changes in the background EEG were not noticed after administration. These data suggest that the broad-spectrum antiepileptic loreclezole can be a valuable new drug in the treatment of absence epilepsy.
