Comparison of the effects of budesonide/formoterol maintenance and reliever therapy with fluticasone/salmeterol fixed-dose treatment on airway inflammation and small airway impairment in patients who need to step-up from inhaled corticosteroid monotherapy.

摘要

For stepping up treatment from ICS alone to an ICS/LABA combination, SMART is preferable for controlling asthma symptoms by suppressing airway inflammation and improving small airway impairment compared with a fixed dose of FP/SM. It may be achieved by the property of BUD/FM itself and as-needed use, but the degree of each contribution must be investigated further.
