title: [Comparative study of the sedative and tranquilizing effect of phenazepama and seduxen and their influence on human evoked brain potentials].
abstract: Phenazepam was compared to diazepam in a double-blind study made in 32 patients. The drugs were administered by month in doses of 0.0025 mg/kg and 0.005 mg/kg. respectively 1--2 days before surgery with the use of general anesthesia. Anxiety assessed by means of the brain evoked potential test and by a clinical test according to Gologorsky's scale reduced 2 hours following both phenazepam and diazepam administration. Phenazepam elicited a more pronounced and more lasting tranquilizing effect as compared to that of diazepam. Phenazepam was concluded to be a powerful anxiolytic and sedative agent recommended for premedication before surgical interventions.
