Brief summary
It is our primary hypothesis that pretreatment with arformoterol will provide superior protection against EIB in children with mild-moderate asthma compared to placebo added to the current asthma regimen. Our secondary hypothesis is that nebulized arformoterol has comparable protection against EIB compared to inhaled formoterol by dry powder inhaler.
Detailed description
This study is a randomized, double-blind, double-dummy, crossover clinical trial which will consist of 5 study visits and will last up to 3 weeks. Fifteen children 12-17 years of age with asthma and EIB, regardless of current asthma therapy will be eligible for this trial.
