The effect of montelukast on bronchial hyperreactivity in preschool children.

INTRODUCTION: The effect of montelukast therapy on bronchial hyperreactivity (BHR) as measured by the methacholine challenge test in preschool children has not yet been reported. OBJECTIVE: To determine the effect of montelukast (4 mg/d) on BHR as evaluated by a provocative concentration of a substance causing a 20% fall in FEV(1) (PC(20)) values in preschool asthmatic children. PATIENTS: A total of 26 preschool children (8 girls) aged 3.3 to 6.0 years (mean [+/- SD] age, 4.7 +/- 0.8 years) with mild asthma. DESIGN: Double-blind randomized, placebo controlled, crossover study. Each child received 4 weeks of treatment with 4 mg of either montelukast or placebo separated by a 2-week washout period. Primary outcomes were PC(20) values and the stage number (triple dose) at which FEV(1) values dropped by 20%(.) Post-montelukast therapy PC(20) was compared to those for the post-placebo period. RESULTS: Following 4 weeks of montelukast treatment, the mean PC(20) was 4.79 +/- 4.69 mg/mL, while after 4 weeks of placebo the mean PC(20) was 2.07 +/- 2.37 mg/mL (p = 0.001). The montelukast/placebo ratio for PC(20) was 2.56 with a 95% confidence interval (CI) of 1.71 to 3.99. The median difference in stage was one triple dose with a 95% CI of 0.5 to 1. 5. CONCLUSIONS: Four weeks of treatment with montelukast resulted in a decreased BHR compared with placebo.[1]
