[Evaluation of antiepileptic effects of cortexin in a model of convulsions].
We studied antiepileptic effects of cortexin administered in doses 0,015, 0,15 and 1,0 mg/kg intraperitoneally in solution or intranasally in the complex with nanoparticles in a model of acute and chronic convulsions in rats induced by pentylenetetrazole. In the model of epileptic status, the long-term preliminary administration of cortexin had no effect on convulsions while in the model of chronic convulsions (temporal epilepsy), cortexin had a marked dose-dependent antiepileptic effect. The influence of cortexin on neuroplasticity and its clinical potential are discussed.
