Opioid receptors are expressed on peripheral sensory nerve endings, cutaneous cells, and immune cells; and local application of opioids is used for the treatment of inflammatory pain in arthritis, burns, skin grafts, and chronic wounds. However, peripherally active opioids can also directly modulate the inflammatory process and wound healing. Here, we discuss the underlying mechanisms of opioid action and the conceivable therapeutic approaches for opioid treatment, as investigated in experimental and clinical studies. A large number of in vitro experiments and animal model investigations have produced evidence that peripherally active opioids can reduce plasma extravasation, vasodilation, proinflammatory neuropeptides, immune mediators, and tissue destruction. In contrast to currently available anti-inflammatory agents, opioids have not demonstrated organ toxicity, thus making them interesting candidates for drug development. Few clinical studies have tapped into this potential to date.
阿片受体表达在外周感觉神经末梢、皮肤细胞和免疫细胞上;局部应用阿片类药物可用于治疗关节炎、烧伤、皮肤移植和慢性伤口的炎症性疼痛。然而,外周作用的阿片类药物也可以直接调节炎症过程和伤口愈合。在这里,我们讨论了阿片类药物作用的潜在机制以及在实验和临床研究中调查的阿片类药物治疗的可行治疗方法。大量的体外实验和动物模型研究已经证明,外周作用的阿片类药物可以减少血浆渗出、血管扩张、促炎神经肽、免疫介质和组织破坏。与现有的抗炎药物不同,阿片类药物没有表现出器官毒性,因此它们成为药物开发的有趣候选药物。迄今为止,很少有临床研究挖掘出这种潜力。
