简要总结
Determine the 24-hour FEV1-profile of tiotropium solution for inhalation after 4 weeks treatment periods of 5 mcg tiotropium administered once daily in the evening and 2.5 mcg tiotropium administered twice daily (morning and evening). In addition compare the 24 hours pharmacokinetic profile of 5 mcg tiotropium administered once daily and 2.5mcg tiotropium administered twice daily in pharmacokinetic sub-investigation.

结局指标
主要结局
Forced Expiratory Volume in One Second (FEV1) Area Under the Curve From 0 - 24h (AUC 0-24) Response.
时间窗: Baseline FEV1 taken at visit 2 prior to the first evening dose of randomised study medication. Then, 10 minutes (min) prior to dose to 30 min,1 hour (h),2h,3h,4h,11h50min,12h30min,13h,14h,15h,16h,18h,20h,22h and 23h,23h50min relative to dose after 4 weeks
Mixed Model Repeated Measure (MMRM) results. Response was defined as change from baseline. Means are adjusted for treatment, period, patient and study baseline.Measured following the respective dosing determined at the end of each 4 week period of randomised treatment. AUC0-24h calculated using the trapezoidal rule divided by the observation time (24 hours) to report in litres. The values recorded at 11 hours 50 minutes and at 23 hours 50 minutes post dosing were assigned to 12 and 24 hours, respectively.
