Primary Outcome Measures:
  • Change From Baseline in FEV1 Over 4 Hours [ Time Frame: 0 (=baseline) to 4 hours after treatment with montelukast ] [ Designated as safety issue: No ]
    FEV1 measurements taken at 0 (=baseline), 10, 20, 30, 45, 60, 120, 180 and 240 minutes contributed to the average change from baseline over 4 hours. The number of minutes between consecutive measurements was used as weighting factor. The time-weighted average change was standardized by dividing by the time associated with the last measurement.


Secondary Outcome Measures:
  • Change From Baseline in FEV1 Over 90 Minutes After Albuterol/Placebo Administration [ Time Frame: 4 hours (equals time point at which albuterol or albuterol placebo is administered) to 5.5 hours after treatment with montelukast ] [ Designated as safety issue: No ]
    FEV1 measurements taken at 0 (=baseline), 15, 30, 60, and 90 minutes after albuterol/placebo administration contributed to the average change from baseline over 90 minutes. The number of minutes between consecutive measurements was used as weighting factor. The time-weighted average change was standardized by dividing by the time associated with the last measurement.
