About 220 participants were randomly assigned (1:1) to either the duloxetine combined with pregabalin or the amitriptyline combined with pregabalin. The patient takes duloxetine or amitriptyline orally before bedtime for 6\u2009weeks each time. Perform a 2\u2010week single\u2010blind placebo washout between the two treatments, and a 2\u2010week single\u2010blind placebo washout at the end of the treatment period. In the last week of the treatment cycle, evaluate the 7\u2010day average daily pain, Pittsburgh Sleep Quality Index, 17\u2010item Hamilton Depression Rating Scale, 36\u2010Item Short Form Health Survey, and record the occurrence of major adverse events. A median reduction of 50%, 25%\u201350%, and 25% in pain score is considered good, moderate, and mild improvement, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Both treatment methods can significantly improve the baseline pain value (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001 for both). The combination of duloxetine and pregabalin resulted in good, moderate, and mild pain relief of 52%, 24%, and 7%, respectively. The combination of amitriptyline and pregabalin resulted in good, moderate, and mild pain relief of 48%, 21%, and 9%, respectively. There was no significant difference in the measurement of various results between the two groups. In the reported adverse events, patients in the amitriptyline group had significantly more dry mouth compared to the duloxetine group (26% vs. 11%; <jats:italic>p<\/jats:italic>\u2009=\u20090.008).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Duloxetine and amitriptyline have similar analgesic effects, and the difference is not statistically significant. The combination of pregabalin has good tolerability and better pain relief in PHN patients, thus providing clinically relevant benefits.<\/jats:p><jats:p><jats:bold>Trial Registration:<\/jats:bold> Chinese Clinical Trial Registry: ChiCTR2100054831<\/jats:p><\/jats:sec>","DOI":"10.1111\/cns.70460","type":"journal-article","created":{"date-parts":[[2025,5,26]],"date-time":"2025-05-26T08:24:20Z","timestamp":1748247860000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Comparison of Duloxetine Supplemented With Pregabalin and Amitriptyline Supplemented With Pregabalin for the Treatment of Postherpetic Neuralgia: A Double\u2010Blind, Randomized Crossover Trial"],"prefix":"10.1111","volume":"31","author":[{"given":"Yue","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"},{"name":"Department of Gastroenterology Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chenchen","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"},{"name":"Department of Gastroenterology Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanan","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youpan","family":"Lou","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qianqian","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xihan","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"},{"name":"Department of Pain Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"},{"name":"Department of Pain Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2968-2343","authenticated-orcid":false,"given":"Ying","family":"Huang","sequence":"additional","affiliation":[{"name":"Department of Pain Nanjing Drum Tower Hospital Clinical College of Nanjing University of Chinese Medicine  Nanjing China"},{"name":"Department of Pain Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University  Nanjing China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,26]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.3390\/v14020192"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.4103\/JCAS.JCAS_45_20"},{"issue":"1533","key":"e_1_2_10_4_1","first-page":"19","article-title":"Efficacy of Pain Relief in Different Postherpetic Neuralgia Therapies:A Network Meta\u2010Analysis","volume":"21","author":"Dehua Song A.
