Tidsramme
Change From Baseline in Trough Forced Expiratory Volume in 1 Second (FEV1)
Tidsramme: Baseline, 24, 24.5 hrs post-dose
FEV1 was the mean volume of air that can be forced out in 1 second after taking a deep breath. Trough FEV1 was calculated as the average of the largest FEV1 value from 3 readings recorded at 24 hours (hrs) and 24.5 hrs post-dose. Baseline FEV1 value was calculated as average of 2 largest pre-dose readings on Day 1 for each period. Change from baseline in trough FEV1 was the difference between trough FEV1 and baseline FEV1.

Tidsramme
Peak Forced Expiratory Volume in 1 Second (FEV1)
Tidsramme: Baseline up to 48 hrs post-dose
FEV1 was the mean volume of air that can be forced out in 1 second after taking a deep breath. Peak FEV1 was defined as change from baseline in maximum FEV1. Maximum FEV1 = maximum forced expiratory volume in 1 second, recorded between 0.5 hrs to 48 hrs post-dose. Baseline FEV1 value was calculated as average of two largest pre-dose readings on Day 1 for each period.
Baseline up to 48 hrs post-dose
Weighted Average Forced Expiratory Volume in 1 Second (FEV1) Response
Tidsramme: Baseline up to 24.5 hrs post-dose
FEV1 was the mean volume of air that can be forced out in 1 second after taking a deep breath. Weighted average FEV1 was defined as the average area under the effect curve (AUEC) change from baseline FEV1 (the area under the FEV1 effect curve over 24.5 hrs post-dose for each study period corrected for the pre-dose baseline value) divided by 24.5. Baseline FEV1 value was calculated as the average of two largest pre-dose readings on Day 1 for each period.
Baseline up to 24.5 hrs post-dose
Change From Baseline in Force Vital Capacity (FVC)
Tidsramme: Baseline, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 24.5, 36, 48 hrs post-dose
FVC was the maximum amount of air exhaled from the lungs after taking the deepest breath possible. Baseline FVC value was calculated as average of two largest pre-dose readings on Day 1 for each period. Change from baseline in FVC was the difference between FVC and baseline FVC.
Baseline, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 24.5, 36, 48 hrs post-dose

Tidsramme: Baseline, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 24.5, 36, 48 hrs pot-dose
IC was the maximum volume of air that can be inhaled in to the lungs after breathing out normally. Baseline IC value was calculated as average of two largest pre-dose readings on Day 1 for each period. Change from baseline in IC was the difference between IC and baseline IC.
Baseline, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 24.5, 36, 48 hrs pot-dose
