Ro15-4513 antagonizes depression of open-field horizontal activity by ethanol in rats.


The imidazobenzodiazepine, Ro15-4513, has been shown to antagonize some of the behavioral effects of ethanol (ETOH). In rats having relatively little experience in the open field, the actions of ETOH (0.75 g/kg IP), Ro15-4513 (1.25 mg/kg and 2.5 mg/kg, IP), and Ro15-4513 in combination with ETOH were measured on horizontal activity. Rats receiving ETOH… (More)
