Flupirtine pretreatment effectively blocks hypoxia-induced behavioral seizures. All the P10 rat pups pretreated with 50 (5/5), 45 (3/3) or 35 (5/5) mg/kg flupirtine that were exposed to graded global hypoxia remained seizure free, i.e., none of them developed behavioral seizures during hypoxia. None of the rats pretreated with vehicle (12/12) and 60% rats pretreated with 25mg/kg flupirtine (5/8) remained seizure free. Statistical comparisons were made individually between the vehicle treated group and each of the flupirtine treated groups. *p<0.005, Fisher's exact test. Hy = Hypoxia, Veh = Vehicle, Flup = Flupirtine.
