骨关节炎(OA)疼痛的理解和管理不足,因为目前的镇痛药只有有限的疗效和不必要的副作用。更广泛地了解驱动OA关节疼痛的病理机制对于开发改进的镇痛药至关重要。临床和临床前数据均表明,OA期间感觉神经肽降钙素基因相关肽(CGRP)的关节水平与疼痛之间存在关联。是否存在直接的因果联系仍然是一个重要的悬而未决的问题。鉴于最近开发的小分子CGRP受体拮抗剂对偏头痛具有临床疗效,询问CGRP在OA疼痛机制中的作用非常及时。在这篇文章中,我们提供了背景的重要性,CGRP在疼痛机制和审查的新兴临床和临床前证据暗示的作用,CGRP在OA疼痛。我们认为,CGRP受体拮抗剂开发的偏头痛值得进一步调查在OA。
Osteoarthritis (OA) pain is poorly understood and managed, as current analgesics have only limited efficacy and unwanted side effect profiles. A broader understanding of the pathological mechanisms driving OA joint pain is vital for the development of improved analgesics. Both clinical and preclinical data suggest an association between joint levels of the sensory neuropeptide calcitonin gene-related peptide (CGRP) and pain during OA. Whether a direct causative link exists remains an important unanswered question. Given the recent development of small molecule CGRP receptor antagonists with clinical efficacy against migraine pain, the interrogation of the role of CGRP in OA pain mechanisms is extremely timely. In this article, we provide the background to the importance of CGRP in pain mechanisms and review the emerging clinical and preclinical evidence implicating a role for CGRP in OA pain. We suggest that the CGRP receptor antagonists developed for migraine pain warrant further investigation in OA.
