Rhesus monkeys were trained to discriminate saline from an injection of ketamine. In tests of stimulus generalization, phencyclidine (PCP) produced dose-related ketamine-appropriate responding in each monkey. Two monohydroxylated PCP metabolites also produced ketamine-like discriminative effects, although only at considerably higher doses than did PCP. A third monohydroxylated PCP metabolite produced only sham-appropriate responding. The results suggest that these PCP metabolites contribute little to the behavioral actions of PCP in the monkey.
