Discriminable effects of benzodiazepines.

Abstract

In a shock-escape T-maze task, rats rapidly discriminated diazepam, flurazepam and chloridazepoxide from no drug. The discriminable effects of these benzodiazepines were not completely interchangeable with those of barbiturate anesthetics. The dose-response curve for diazepam asymptoted over the range 15 to 100 mg/kg, ip whereas dose-response curves for flurazepam and chloridazepoxide were more linear.
