The ability of cocaethylene to produce either a conditioned place preference or a conditioned place aversion was tested in rats. Twelve male rats were administered 10 mg/kg cocaethylene and confined to their nonpreferred side of the conditioned place preference apparatus as determined on a baseline test day. Subsequently, these rats spent a greater amount of time in that cocaethylene-paired nonpreferred side when later tested in a drug-free state. In contrast, rats conditioned with the same dose of cocaethylene and confined in their preferred side, as well as other rats treated with saline on both sides, did not show a significant shift in their preference or aversion. Results are discussed in light of the rewarding activity of cocaethylene, a compound formed in humans who concurrently use cocaine and ethanol.

D003042 Cocaine An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
