Anticonvulsant activities of myo-inositol and scyllo-inositol on pentylenetetrazol induced seizures.

Abstract

Myo-inositol (MI) and its isomers are used for the treatment of various neuropathological conditions. The purpose of the present research was to study anticonvulsant properties of MI and scyllo-inositol (SCI) on pentylenetetrazol (PTZ) induced seizures in rats. Half an hour after treatment with MI (30 mg/kg) or SCI (5 mg/kg) seizures were induced in Wistar rats with PTZ (60 mg/kg). Control animals were treated either by normal saline or mannitol (control polyol of the same molecular weight, 30 mg/kg), given at the same time interval before PTZ injection, as MI/SCI groups. The anticonvulsant effects of MI/SCI treatment were assessed by the latent period (the time from PTZ-injection to the onset of first seizures), and the duration and severity (score) of seizures. The mortality rate was also assessed. Both MI and SCI treatment significantly reduced the seizure score, seizure duration and increased the latent period. These data suggest for strong potential of MI and SCI as the agents of antiepileptic therapy.
