Primary Outcome Measures
NameTimeMethod
Forced Expiratory Volume in 1 Second (FEV1) at 5 Minutes Post-doseFive Minutes Post Dose

FEV1 was measured at 5 minutes after dosing with spirometry conducted according to internationally accepted standards. The time of dosing was defined as the time corresponding to the use of the first inhaler device. The primary variable was analyzed using a mixed model containing the period baseline FEV1 as covariate. The period baseline FEV1 was the average of the FEV1 value measured in the clinic at 50 and 15 min prior to the study drug administration in that period.
