Condition(s) targeted: Asthma
Intervention: Levalbuterol HFA MDI followed by Racemic albuterol HFA MDI (Drug); Racemic Albuterol followed by levalbuterol HFA MDI (Drug)
Phase: Phase 2
Sponsored by: Sepracor, Inc.
The purpose of this study is to compare the safety and tolerability of levalbuterol HFA
metered dose inhaler (MDI) versus racemic albuterol HFA MDI in pediatric subjects 4-11 years
of age with asthma
Official title: A Cumulative Dose Tolerability Study of Levalbuterol HFA and Racemic Albuterol HFA in Pediatric Subjects With Asthma
Study design: Treatment, Randomized, Double Blind (Subject, Investigator), Crossover Assignment, Safety/Efficacy Study
Primary outcome: Increases from visit pre-dose to each post-dose dose measurement in heart rate, blood pressure (systolic and diastolic), potassium and glucose
Percent change in FEV1 (from visit pre-dose to each post dose measure)
Percent change in FVC (from visit pre-dose to each post dose measure)
Percent change in FEF25-75% (from visit pre-dose to each post dose measure)
