Effectiveness and safety of Suhuang Zhike capsule as adjuvant treatment for acute exacerbation of chronic obstructive pulmonary disease: a systematic review and Meta-analysis.

Abstract

Objective: To evaluate the efficacy and safety of Suhuang Zhike capsule in the adjuvant treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).

Methods: The database including PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Chinese Biomedical Literature Database and Wanfang Data was searched. The retrieval time was from database establishment to May 2021. Randomized controlled trial (RCT) of Suhuang zhike capsule adjuvant treatment for AECOPD was included. The quality of the studies was independently evaluated and cross-checked by two reviewers, and Meta-analysis was performed by using RevMan5.3 software.

Results: Thirteen RCT results were included with a total sample number of 1195 cases, including 597 in the experimental group and 598 in the control group. The results showed that Suhuang zhike capsule adjuvant treatment of AECOPD could improve the total clinical effect rate compared with conventional treatment. Suhuang zhike capsule adjuvant treatment could improve forced vital capacity (FVC), forced expiratory volume in one second (FEV), FEV/FVC, peak expiratory flow (PEF) and other pulmonary function indexes; decrease C-reactive protein (CRP), white blood cells, neutrophils and other infectious indicators; besides, the 1-year recurrence rate of the disease was decreased (all 0.05).

Conclusions: Suhuang Zhike capsule can improve the lung function and clinical efficacy of AECOPD, thus increasing the exercise endurance, and reducing the infection and recurrence rate in AECOPD patients.
