This approach was taken because chlordiazepoxide produces anxiolytic-like effects in multiple models in adult rodents, however, less is known about the behavioral effects of this benzodiazepine in juveniles. Thus, we administered a single intraperitoneal injection of chlordiazepoxide (0, 5, or 10 mg/kg) to postnatal day 35 male C57BL/6 mice. Thirty minutes later, mice were allowed to explore the EPM for 5-min. We found that chlordiazepoxide-treated mice (5 and 10 mg/kg) spent more time exploring the open arms of the EPM. No differences in velocity (cm/s) or distance traveled (cm) were observed between the groups. These results indicate that chlordiazepoxide induces anxiolytic-related behavior in adolescent male mice.
