Budesonide/formoterol improves lung function compared with budesonide alone in children with asthma.

UNLABELLED: We aimed to compare the efficacy and safety of budesonide/formoterol (Symbicort) with budesonide alone (Pulmicort) or budesonide (Pulmicort) and formoterol (Oxis) administered via separate inhalers in children with asthma. In a 12 wk, double-blind study, a total of 630 children with asthma (mean age 8 yr [4-11 yr]; mean forced expiratory volume in 1 s (FEV(1)) 92% predicted; mean inhaled corticosteroid dose 454 microg/day) were randomized to: budesonide/formoterol (80/4.5 microg, two inhalations twice daily); a corresponding dose of budesonide alone (100 microg, two inhalations twice daily); or a corresponding dose of budesonide (100 microg, two inhalations twice daily) and formoterol (4.5 microg, two inhalations twice daily) (budesonide + formoterol in separate inhalers). The primary efficacy variable was the change from baseline to treatment (average of the 12-wk treatment period) in morning peak expiratory flow (PEF). Other changes in lung function and asthma symptoms were assessed, as was safety. Budesonide/formoterol significantly improved morning PEF, evening PEF and FEV(1) compared with budesonide (all p < 0.001); there was no significant difference between budesonide/formoterol and budesonide + formoterol in separate inhalers for these variables. All other diary card variables improved from baseline in all treatment groups; there were no significant between-group differences. Adverse-event profiles were similar in all groups; there were no serious asthma-related adverse events in any treatment group.
CONCLUSION: budesonide/formoterol significantly improved lung function in children (aged 4-11 yr) with asthma compared with budesonide alone. Budesonide/formoterol is a safe and effective treatment option for children with asthma.
