The present study compared the behavioral and toxic effects of cocaine and its ethanol derived metabolite, cocaine ethyl-ester (cocaethylene). Both drugs produced qualitatively similar psychomotor stimulant effects. Cocaine and cocaethylene increased locomotor activity in mice, with cocaine approximately four times more potent than cocaethylene. The durations of action of ED75 doses of each of the drugs were comparable. Each of the drugs also produced stimulation of operant responding in rats. In rats and squirrel monkeys trained to discriminate cocaine injections from saline, cocaine was approximately three to five times more potent than cocaethylene in producing these cocaine-like interoceptive effects. In contrast to the behavioral effects, cocaine and cocaethylene were equipotent in producing convulsions, and cocaethylene was more potent than cocaine in producing lethality. These results suggest that the conversion of cocaine to cocaethylene with simultaneous cocaine and alcohol use may produce an increased risk of toxicity due to a decrease in the potency of cocaethylene in producing psychomotor stimulant effects, and its increased potency in producing toxicity.
