The reinforcing and discriminative stimulus effects of brotizolam, a benzodiazepine-hypnotic, were evaluated in rhesus monkeys. In one experiment, separate groups of monkeys (N = 3 group) were trained to discriminate pentobarbital (10 mg/kg, IG) or d-amphetamine. (0.56-1.0 mg/kg, IG) from saline, in a discrete-trials avoidance/escape paradigm. Pentobarbital (5.6-10 mg/kg), diazepam (1.0-1.7 mg/kg), and brotizolam (0.3-1.7 mg/kg) resulted in 100% drug-lever responding in all three pentobarbital-trained monkeys. In d-amphetamine-trained monkeys brotizolam administration resulted only in saline-lever responding. In another experiment, monkeys were surgically prepared with indwelling intravenous catheters and lever pressing resulted in an injection of 0.1 mg/kg/injection sodium methohexital under a fixed-ratio 10 (FR 10) schedule. Pentobarbital (0.01-0.3 mg/kg/injection) and diazepam (0.003-0.10 mg/kg/injection) maintained responding above saline control levels when substituted for methohexital. Brotizolam (0.001-0.01 mg/kg/injection) resulted in more injections received compared to saline, but fewer injections compared to pentobarbital or diazepam. Thus, results from the present experiment suggest that brotizolam would have pentobarbital-like subjective effects. However, the abuse liability of brotizolam may be lower than that for diazepam.
