ObjectiveTo systematically review the efficacy and safety of Yangyinqingfei decoction for chronic cough and chronic obstructive pulmonary disease (COPD) patients.MethodsWe electronically searched databases including PubMed, Web of Science, CBM, CNKI, VIP and WanFang Data for randomized controlled trials (RCTs) of Yangyinqingfei decoction for chronic cough and COPD patients from inception to August 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis.ResultsTwenty-four RCTs involving 2 268 patients with COPD and chronic cough were included. The results of meta-analysis showed that compared with the control group, Yangyinqingfei decoction combined with the conventional medicine could significantly improve clinical effective rate (RR=1.21, 95%CI 1.16 to 1.27, P<0.000 01) and lung function (SMD=0.76, 95%CI 0.59 to 0.94, P<0.000 01) in patients with COPD. Yangyinqingfei decoction combined with the conventional medicine group was superior to the control group (RR=1.41, 95%CI 1.22 to 1.64, P<0.000 01) in clinical efficacy for adults patients with chronic cough. In terms of safety, seven cases occurred adverse reactions in the Yangyinqingfei decoction group, while 13 were found in the control group, the types and degree of adverse reactions in both groups were almost the same.ConclusionThe combination of Yangyinqingfei plus conventional medicine may significantly improve the clinical efficacy for chronic cough and COPD with reliable safety. However, due to the limited quality and quantity of included studies, the above conclusions are needed to verify by more high quality studies.
