Review Meta Analysis Comparative Study
Long-acting muscarinic antagonist + long-acting beta agonist versus long-acting beta agonist + inhaled corticosteroid for COPD: A systematic review and meta-analysis.
Some trials have been conducted to compare long-acting muscarinic antagonist (LAMA) + long-acting beta agonist (LABA) versus LABA + inhaled corticosteroids (ICS) for chronic obstructive pulmonary disease (COPD), but no meta-analysis were reported. Two investigators independently searched for eligible articles using the PubMed, Web of Science and Cochrane databases. Articles in authors' reference files were also regarded as candidates. ⋯ Compared with LABA + ICS, LAMA + LABA led to significantly greater improvements of trough FEV1 by 71 (95% CI: 48-95) mL, TDI by 0.38 points (95% CI: 0.17-0.58), less exacerbations with an OR of 0.77 (95% CI: 0.62-0.96) and less pneumonia with an OR of 0.28 (95% CI: 0.12-0.68). Frequencies of any adverse event, serious adverse event, adverse event leading to discontinuation, all-cause death and change of total score of SGRQ were not different in both arms. LAMA + LABA might be a better option for treating COPD than LABA + ICS.
