ABSTRACT

The short-acting beta-2 agonist (SABA) assist use protocol aids patients with chronic obstructive pulmonary disease (COPD). The purpose of this study was to investigate the effect of regularly inhaled long-acting bronchodilators on SABA assist use. Between September 2013 and January 2015, exercise tolerability was evaluated using the incremental shuttle-walking test (ISWT); we tested 72 patients with COPD before and after SABA assist use. In the long-acting muscarinic antagonist (LAMA) group, the difference in walking distance was 14.4±9.3m, whereas in the long-acting beta-2 agonist (LABA) group the distance was 4.1±6.4m. Thus, any improvement in exercise tolerance tended to be minimal in the LABA group. This implies that differences in the periodicity of inhaled medicine may affect the utility of SABA assist use.
