Background:
Budesonide inhalation suspension and the leukotriene receptor antagonist montelukast have demonstrated efficacy in children with mild persistent asthma, but comparative long-term studies in young children are needed.
Objective:
To compare the long-term efficacy and safety of budesonide inhalation suspension and montelukast.
Methods:
After a run-in period, children 2 to 8 years old with mild asthma or recurrent wheezing were randomized to once-daily budesonide inhalation suspension 0.5 mg or once-daily oral montelukast 4 or 5 mg for 52 weeks. Subjects were stepped up to twice-daily budesonide inhalation suspension or oral corticosteroids for mild or severe asthma worsening, respectively. The primary outcome was time to first additional medication for asthma worsening at 52 weeks. Secondary variables included times to the first additional asthma medication measured at 12 and 26 weeks; times to the first asthma exacerbation (mild and severe) measured at 12, 26, and 52 weeks; exacerbation rates (mild and severe) over a period of 52 weeks; diary variables (eg, peak expiratory flow [PEF]); patient-reported outcomes; and Global Physician and Caregiver Assessments.
Results:
No significant between-group differences were observed for time to first additional asthma medication at 52 weeks; however, time to first additional asthma medication was longer (unadjusted P = .050) at 12 weeks and exacerbation rates were lower over a period of 52 weeks (unadjusted P = .034) for budesonide versus montelukast. Time to first severe exacerbation (requiring oral corticosteroids) was similar in both groups, but the percentage of subjects requiring oral corticosteroids over a period of 52 weeks was lower with budesonide (25.5% vs 32.0%). Peak flow and Caregiver and Physician Global Assessments favored budesonide.
Conclusion:
Both treatments provided acceptable asthma control; however, overall measures favored budesonide inhalation suspension over montelukast.
Clinical Implications:
These findings are consistent with studies in older children demonstrating better outcomes with inhaled corticosteroids versus montelukast.

ICS work through a multifaceted mechanism of action. They suppress the inflammatory response caused by the proliferation of TH cells. They also reduce the transcription of the IL-2 gene, which is involved in the...

Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
