Clinical Trial Summary

Rationale for the current trial is to demonstrate 24 hour bronchodilator efficacy and safety of tiotropium 5 µg administered once daily (in the evening) which is regarded beneficial for the compliance and convenience of the patient in comparison to placebo. Further the rationale is to evaluate efficacy and safety of tiotropium 2.5 µg administered twice daily delivered by the Respimat® inhaler in comparison to placebo and tiotropium 5 µg administered once daily (in the evening) delivered by the Respimat® inhaler in patients with moderate persistent asthma.

Rationale for the pharmacokinetic subinvestigation is to evaluate the 24 hours exposure to tiotropium in patients with moderate persistent asthma when administered 5 µg tiotropium once daily (in the evening) or 2.5 µg tiotropium twice daily.
