The purpose of this study is to determine in a large, double-blind, randomized, prospective pediatric clinical trial whether the use of continuous levalbuterol (Xopenex) in addition to standard emergency department treatment for acute asthma exacerbations will improve the Forced Expiratory Volume in 1 sec (FEV 1) compared to the use of continuous racemic albuterol. The secondary objective is to correlate clinical (hospitalization rates and clinical asthma scores) with plasma levels of (S)-albuterol.

Condition Intervention Phase
Asthma Drug: xopenex Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Comparison of Hospital Admission Rates and Plasma(s)-Albuterol Levels in Children Treated With Racemic Albuterol Versus Levalbuterol for Acute Asthma Exacerbations: A Randomized Double-Blind Clinical Trial

Primary Outcome Measures:
  • Change in Forced Expiratory Volume in 1 Sec (FEV1) Measured in L/Sec [ Time Frame: Baseline and 4 hours ]

Secondary Outcome Measures:
  • Clinical Asthma Score (CAS) [ Time Frame: 4 hours ]
    Change in clinical asthma score while in ED. 15 point clinical asthma score. Score ranges from 5 (no to mild respiratory distress) to a maximum of 15 (severe respiratory distress).
