  Purpose
The purpose of this study is to determine the effect of montelukast, an approved medication, on the lower leg growth rate in children with mild asthma. The primary hypothesis is that the lower leg length (LLL) growth rate for children treated with montelukast compared to placebo will be established.

Condition Intervention Phase
Asthma, Bronchial Drug: Montelukast chewable tablets Drug: Budesonide inhaler Drug: Placebo to montelukast chewable tablets Drug: Placebo to budesonide inhaler Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A Double-Blind, Double-Dummy, Randomized, Placebo-Controlled, 2-Arm, 2X2 Crossover Study Comparing the Effects of Montelukast, Inhaled Budesonide, and Placebo on Lower Leg Growth in Children (Prepubertal, Tanner Stage I) With Mild Asthma
