Capsaicin, derived from the chilli pepper plant, is available in high concentration (8%) patches to provide topical therapy for neuropathic pain. Its analgesic effects relate to defunctionalisation and nerve terminal retraction of predominantly C fibres in the dermis and epidermis. Systematic reviews and meta-analysis support its use for the management of post-herpetic neuralgia and HIV neuropathy with some evidence for use in painful peripheral diabetic neuropathy. The article concludes with advice on the practicalities of running a topical 8% capsaicin clinic for peripheral neuropathic pain.
辣椒素源自辣椒植株,有高浓度(8%)的贴片制剂,可用于为神经性疼痛提供局部治疗。其镇痛作用与真皮和表皮中主要为C纤维的功能丧失及神经末梢回缩有关。系统评价和荟萃分析支持其用于治疗带状疱疹后神经痛和HIV相关性神经病变,并有一些证据表明其可用于治疗疼痛性糖尿病周围神经病变。文章最后给出了关于开设8%辣椒素局部治疗周围神经病变门诊的实用建议。
