Abstract

Six benzodiazepine derivatives, given alone or in combination with amphetamine, were tested in mice subjected to five 100-trial avoidance sessions in the shuttle-box. All derivatives, execpt bromazepam, showed some facilitating effects on avoidance responding when given alone. Facilitation was particularly evident following the administration of chlordiazepoxide (2.5 mg/kg), medazepam (10 mg/kg) and nitrazepam (0.25, 0.5 and 1 mg/kg). Favourable effects were obtained by combining each benzodiazepine compound with amphetamine. The levels of avoidance respinses were usually higher under benzodiazepine-amphetamine combinations than under benzodiazepines alone.

How strong is the evidence?

Evidence Hub reads this as a review, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
