Review Meta Analysis Comparative Study
Long-acting Muscarinic Antagonist Versus Inhaled Corticosteroid when Added to Long-acting β-agonist for COPD: A Meta-analysis.
The purpose of this study was to systematically review the efficacy and safety of long-acting β-agonist/long-acting muscarinic antagonist (LABA/LAMA) and LABA/inhaled corticosteroid (ICS) combinations in patients with advanced chronic obstructive pulmonary disease (COPD). Randomized clinical trials of at least 12 weeks of duration comparing LABA/LAMA and LABA/ICS combinations were included. We chose forced expiratory volume in 1 second (FEV1), St. ⋯ There was no significant difference in safety and exacerbation outcomes. However, equivalence of two treatments could not be concluded due to imprecision especially for mortality, cardiac serious adverse events, and severe exacerbations. Our findings support the use of dual long-acting bronchodilators for patients with advanced COPD but without frequent exacerbations given the excess risk of pneumonia with LABA/ICS.
