Abstract:
Objective To study the effect of flumazenil on hypnotic mice induced by diazepam and zolpidem ,and to eval-uate the possibility of flumazenil oral administration .Methods First ,Kunming mice were injected intraperitoneally with nor-mal saline and sodium pentobarbital (S + W) ,diazepam and pentobarbital sodium (D + W) ,zolpidem and pentobarbital sodi-um (Z + W) .The hypnotic effect of diazepam and zolpidem on prolonging the sleep time of pentobarbital sodium would be ver-ified by (D + W) group and (Z + W) group .Then the mice were injected intraperitoneally with flumazenil .The sleep time was used as the evaluation index to evaluate the effect of flumazenil against hypnosis . Finally , the oral administration of flumazenil was observed against hypnosis ,which was evaluated by using sleep time as an index .Results Compared with the control group (S+W) ,the diazepam group (D+W) and the zolpidem group (Z+W) significantly prolonged the sleep time in-duced by pentobarbital sodium (P<0 .001 ,P<0 .05);After Intraperitoneal injection of flumazenil ,compared with the diazepam group (D+W) and the zolpidem group (Z+W) ,the sleep time of the diazepam group [F(ip)+D+W] and the zolpidem group [F(ip)+Z+W] were significantly shorter (P<0 .001 ,P<0 .05);After oral administration of flumazenil ,the sleep time of the diazepam group [F(ig)+ D+ W] and the zolpidem group [F(ig)+ Z+ W] were also significantly shorter (P< 0 .001 ,P<0.05) .Conclusion Flumazenil ,whether intraperitoneal injection or intragastric administration ,could antagonize the hypnotic effect of diazepam and zolpidem .It was proved that oral administration of flumazenil had the same effect compared with intrap-eritoneal injection of flumazenil ,which provided the possibility of preparation of oral administration of flumazenil .
