Title: Effect of Inhalation of a Free Combination of Tiotropium Once Daily 18 Mcg and Salmeterol Twice Daily 50 Mcg Versus a Fixed Combination of Fluticasone and Salmeterol Twice Daily (500/50 Mcg) on Static Lung Volumes and Exercise Tolerance in COPD Patients (a Randomised, Double-blind, Double Dummy, 16 (2 x 8) Weeks, Crossover Study).
Brief Summary: The primary objective of this study is to demonstrate that treatment with a free combination of tiotropium and salmeterol provides superior improvement in static lung volumes and exercise tolerance compared to a fixed combination of fluticasone and salmeterol in patients with COPD.

The secondary objective includes assessment of safety.
