摘要: Abstract Diprenorphine, naloxone, MR-2266-BS and WIN-44,441-3 were compared for their ability to antagonize morphine analgesia decrease deprivation-induced drinking in rats. Diprenorphine naloxone markedly more potent (32 ×) than antagonizing the analgesic effects of morphine. In contrast, diprenorphine, decreased over a similar dose range. The doses required reduce fluid consumption higher those necessary was ineffective decreasing drinking. relatively potencies suggest that effect on involves antagonist activity at κ-opioid receptor.
