英文摘要

AIM: To study the potential of the psychological dependence of tramadol. METHODS: Rats were trained to discriminate 4.0 mg/kg morphine, and to discriminate 0.5 mg/kg methamphetamine (MA) from saline under a fixed-ratio (FR10) schedule of reinforcement. After they acquired the discrimination, different doses of tramadol were used to substitute for training dose of morphine and MA. Naltrexone was injected concomitantly with tramadol. RESULTS: Tramadol fully substituted morphine at a dose of 32 mg/kg or higher. The ED50 value of the discriminative effects of tramadol was 20.94 mg/kg, higher than that of morphine (2.04! mg/kg, P < 0.01). MA failed to generalize to tramadol at the doses tested. Naltrexone antagnized the discriminative respondse of tramadol. CONCLUSION: Tramadol can substitute for morphine in morphine discriminative rats. The discriminative stimulus effects of tramadol are mediated by a mu opioid mechanism.
