Abstract
BACKGROUND:Budesonide is approved for delivery using a nebulized solution and dry-powder inhaler, but its use through a pressurized metered-dose inhaler (pMDI) in pediatric patients with asthma has not been determined. OBJECTIVE: To examine the efficacy and safety of 160 μg twice daily of budesonide through a pMDI vs placebo in children 6 to younger than 12 years with asthma and a demonstrated need for inhaled corticosteroids. METHODS: A 6-week, international, multicenter, double-blinded, parallel-group, phase 2 study randomized 304 pediatric patients (mean age, 9 years; 21.7% <8 years) 1:1 to 160 μg (80 μg × 2 inhalations) twice daily ofbudesonide through a pMDI or placebo after a 7- to 21-day run-in period. The primary efficacy end point was change from baseline in morning peak expiratory flow (PEF); safety end points included adverse events, vital signs, and discontinuations. RESULTS:Budesonide treatment significantly improved morning PEF vs placebo; mean treatment effect (budesonide vs placebo) was 13.6 L/min (P < .0001). Budesonide also showed significant improvements vs placebo for forced expiratory volume in 1 second, evening PEF, forced expiratory flow at 25% to 75% of pulmonary volume, reliever medication use, nighttime awakenings, awakenings with reliever use, and percentage of patients with at least 15- and at least 30-L/min increase in morning PEF from baseline. The numbers of patients experiencing adverse events and discontinuations were smaller in the budesonide than in the placebo group. No serious adverse events were reported. CONCLUSION:Budesonide at 160 μg twice daily through a pMDI was generally well tolerated and significantly improved lung function, symptoms, rescue medication use, and nighttime awakenings vs placebo in children 6 to younger than 12 years with asthma and a demonstrated need for inhaled corticosteroids.
