AB027. Long-acting beta-agonist in combination or separate inhaler as step-up therapy for children with uncontrolled asthma receiving inhaled corticosteroids

摘要

BackgroundAdding a long-acting β2-agonist (LABA) to inhaled corticosteroids (ICS) using a fixed-dose combination (FDC) inhaler containing ICS and LABA is the UK guideline-recommended step-up option for children aged >4 years with uncontrolled asthma on ICS monotherapy. The evidence of benefit of FDC inhalers over adding a separate LABA inhaler to ICS therapy is limited. Our aim was to compare outcomes for FDCversusseparate LABA + ICS inhalers for children by analyzing routinely-acquired clinical and prescribing data.
