Official Title: “A Multicenter, Double-Blind, Randomized, Crossover Design Study to Evaluate the Effect of Montelukast Vs. Salmeterol on the Inhibition of Exercise-Induced Bronchoconstriction in Asthmatic Patients Aged 6-14 Years”

The purpose of this study is to determine the effect of four weeks of treatment with two investigational drugs (oral versus inhaled administration) plus an inhaled medication in the treatment of airway constriction brought on by exercise in asthmatic patients.
