Abstract 【Objective】 This study aimed to access the efficacy and safety of the medication use of long-acting β2-agonist combined with long-acting muscarinic antagonist (LABA/LAMA) for symptomatic COPD patients in the real world. 【Methods】 Patients were enrolled in the study cohort if they were diagnosed as COPD with CAT≥10 scores and new to LAMA/LABA treatment from the Second Xiangya Hospital of Central South University and Zhuzhou Central Hospital during December 2018 and January 2021.Patients enrolled in the study treated with LABA/LAMA 3 for months. According to whether other maintenance medication was used before enrollment, they were divided into 4 groups: the initial group, prior LAMA group,prior ICS/LABA group,prior ICS/LABA plus LAMA group. The effectiveness outcome was the change of CAT scores, the occurrence of moderate to severe acute exacerbations and clinical control during follow-up. Safety outcome was the appearance of adverse effects. 【Results】 Overall study population and patients from the initial group, prior LAMA group, prior ICS/LABA group ameliorated significantly in CAT scores (P<0.05), After 3 months, LABA/LAMA significantly reduced the rate of moderate or severe exacerbations(P<0.05). Study showed a significant improvement in clinical control (P<0.05). The overall incidence of adverse events is low. 【Conclusion】 Patients with COPD symptoms benefit from LABA/LAMA by improving their clinical symptoms, reducing the rate of moderate or severe exacerbations and improving clinical control rates. LABA/LAMA is safe and well tolerated.
