Abstract
BACKGROUND: COPD is characterized by progressive and irreversible air flow limitations. Single-inhaler therapies (SITTs) incorporating an inhaled corticosteroid, a long-acting muscarinic antagonist, and a long-acting [[beta].sub.2]-agonist have been shown to effectively alleviate symptoms and improve lung function. Fluticasone-furoate/umeclidinium/vilanterol (F/U/V) and budesonide/glycopyrronium/formoterol (B/G/F) are available as SITT in Japan. However, the clinical differences between these 2 combinations and the predictors of their proper use have not been established. This study aimed to identify the subject characteristics that could predict the effectiveness of inhaler therapy. METHODS: We assessed the pulmonary function test results of subjects with COPD before and one month after using F/U/V and B/G/F as SITT. Subjects with a difference of 100 mL or more in the [FEV.sub.1] after treatment with pre-SITT were extracted and divided into the F/U/V effect and no-effect group and B/G/F effect and no-effect group to examine the factors associated with positive outcomes with each inhaler. RESULTS: F/U/V and B/G/F significantly improved the inspiratory capacity (IC), %IC, FVC, and %FEV1 when compared to pre-intervention values (P
