Abstract:
OBJECTIVE To systematically evaluate the efficacy and safety of five oral Chinese patent medicines in the treatment of stable chronic obstructive pulmonary disease(COPD).
METHODS A computer-based search was conducted in 7 databases, including CNKI, Wanfang, VIP, CBM, the Cochrane Library, Embase and Pubmed, to identify randomized controlled trial(RCT) of oral proprietary Chinese medicines in the treatment of stable COPD. Additionally, a self-built database was searched, with all searches covering records up to October 1, 2023. Two reviewers independently selected the trials and evaluated the quality. RevMan 5.3, Stata SE 14 and GeMTC 0.14.3 software were used to extract valid data for network meta-analysis.
RESULTS A total of 34 controlled clinical trials were included, including 2385 cases, including 1228 cases in the control group and 1157 cases in the experimental group. The network meta-analysis yielded the following results: ① in terms of improving the effective rate, Gushen Dingchuan pill>Yupingfeng capsule(granules)>Jinshuibao capsule>Bailing capsule>Suhuang Zhike capsule; ② in terms of improving forced expiratory volume in one second, Suhuang Zhike capsule>Gushen Dingchuan pill>Bailing capsule>Yupingfeng capsule(granules)>Jinshuibao capsule; ③ in terms of improving forced vital capacity, Gushen Dingchuan pill>Bailing capsule>Suhuang Zhike capsule>Yupingfeng capsule(granules); ④ in terms of improving the percentage of respiratory volume in the first second to forced vital capacity, Baling capsule>Suhuang Zhike capsule>Yupingfeng capsule(granules)>Jinshuibao capsule>Gushen Dingchuan pill; ⑤ Bailing capsule was more effective than Yupingfeng capsule(granules) in reducing the frequency of acute attacks; ⑥ in terms of safety, no serious adverse reactions occurred in the 5 oral proprietary Chinese medicines.
CONCLUSION The 5 oral Chinese patent medicines have obvious effect in the treatment of stable COPD, with high safety coefficient and mild adverse reactions. However, more high-quality, large-sample, multicenter randomized controlled trials with rigorous design are needed to verify.
