Dezocine Exerts Analgesic Effects in Chronic Pain by Activation of κ- and μ-Opioid Receptors and Inhibition of Norepinephrine and Serotonin Reuptake

Abstract

Conclusion: These results suggest that, in neuropathic pain, the analgesic effects of dezocine are mediated through KOR and MOR activation, together with norepinephrine reuptake inhibition (NRI) and serotonin reuptake inhibition. In contrast, in cancer pain, KOR and MOR activation and NRI are involved in mediating the analgesic effect of dezocine. This study, along with previous data, enhances our understanding of the potential clinical utility of dezocine and elucidates its mechanisms of action in chronic pain management.
