  • Title: Generalization of norcocaine to the discriminative stimulus properties of cocaine.
    Author: Mckenna ML, Ho BT, Englert LF.
    Journal: Pharmacol Biochem Behav; 1979 Feb; 10(2):273-6. PubMed ID: 450938.
    Abstract:
    In rats trained to discriminate 10 mg/kg cocaine from 1 mg/kg saline, norcocaine, the N-demethylated metabolite, at doses of 2.5 mg/kg, 5 mg/kg and 10 mg/kg, produced a dose response curve similar to that of cocaine and generalized to cocaine at the two higher doses. As with cocaine, the discriminative stimulus produced by the norcocaine was partially attenuated by the dopaminergic antagonist pimozide and the amine depletor reserpine. Benzoylecgonine, benzoylnorecgonine and ecgonine methyl ester in doses of 10 mg/kg and 20 mg/kg did not generalize to cocaine.
