Brief communication. Comparative pharmacology of norcocaine in M. mulatta and M. fascicularis.
Norcocaine was administered intravenously (0.05, 0.5, 5.0 mg/kg) to three chaired unanesthetized male rhesus monkeys and to three chaired male cynomolgus monkeys. Respiration rate, heart rate and rectal temperature were monitored. In the rhesus monkeys tachycardia and hyperventilation resulted. However, similar qualitative and quantitative changes were not observed in the cynomolgus species. There was a statistically significant difference in the response to norcocaine across species. These results indicate that cynomolgus monkeys are either less sensitive or respond differently than rhesus monkeys to some of the pharmacological effects of norcocaine. Furthermore, these data confirm that norcocaine is an active derivative of cocaine in both rhesus and cynomolgus monkeys.
