Long-acting beta-agonists (LABAs) have been shown to increase the risk of asthma-related hospitalization among children. This large study shows that the concomitant use of inhaled glucocorticoids with LABAs (ICS/LABA) mitigates those risks. The study was mandated by the Food and Drug Administration (FDA).
6,200 children, 4 to 11 years of age, who required daily asthma medications and had a history of asthma exacerbations in the previous year were randomized to receive fluticasone propionate plus salmeterol or fluticasone alone for 26 weeks.
Salmeterol in a fixed-dose combination with fluticasone was associated with the risk of a serious asthma-related event that was similar to the risk with fluticasone alone.

The World Allergy Organization (WAO) Small Airways Working Group publishes a monthly "What's New?" summary and I have served as its editor since 2011. The summary features the top 3 asthma/small airways articles each month. The article above is a part of the project.
