title: [Cortexolone as a modulator of diazepam activity].
abstract: The influence of ACTH (200 micrograms/kg), corticosterone (20 mg/kg) and cortexolone (20 mg/kg) on the anxiolytic activity of diazepam was studied. ACTH partly and corticosterone completely blocked the action of diazepam. Cortexolone injection 30 min before the administration of diazepam induced a 100% anxiolytic effect of diazepam in the range of doses from 0.1 to 0.3 mg/kg (ED50 of anxiolytic diazepam effect is 0.2 mg/kg). The role of stress hormones in the regulation of psychotropic drug activity is discussed.
