The GABA withdrawal syndrome (GWS) is a new model of focal epilepsy in which paroxysmal activity is induced through the interruption of a chronic, intracortical infusion of GABA. Preliminary studies have shown extraordinary resistance of this epileptogenic activity to classic anticonvulsants including diazepam, the most effective agent for treating status epilepticus. However, GWS can be inhibited by GABA itself. The rat with petit mal-like seizures is a genetic model of generalized non-convulsive epilepsy (GNCE), with behavioral characteristics and electrical (spike-and-wave discharges) signs resembling absences. Moreover, GABAmimetics aggravate this type of seizure. Rats with GWS induced by cessation of a localized GABA infusion (50 micrograms/microliters/h for 24 h), and the rat model of GNCE, were treated with HEPP, a new anticonvulsant agent. In the case of GWS, the drug produced a significant decrease of focal spike activity in animals which started discharging at low frequencies while in rats with higher frequency discharge, HEPP was without effect. HEPP administered on the second day of the GWS in naive rats had no effect. In rats with GNCE, doses of 50 and 100 mg/kg i.p. blocked the spike-and-wave discharges. The higher dose produced sedation in this absence seizures model. Although the mechanism of action of HEPP is still unknown, its unique antiepileptic profile deserves further studies.
