Study Arms:
- Placebo-indacaterol 150μg-indacaterol 300μg-indacaterol 600μg (Type: EXPERIMENTAL): In treatment period, 1 patients received 2 placebo capsules; in treatment period 2, patients received 1 indacaterol 150 μg capsule + 1 placebo capsule; in treatment period 3, patients received 1 indacaterol 300 μg capsule + 1 placebo capsule; and in treatment period 4, patients received 2 indacaterol 300 μg capsules. There was a washout period of 14-28 days between each treatment period. Patients received each treatment only once. The short-acting β2-agonist salbutamol was available for rescue use throughout the study.
