Brief Summary:
The primary objective of this study is to characterize the pharmacokinetics (i.e. systemic exposure to tiotropium and salmeterol) of tiotropium qd + salmeterol qd or bid versus tiotropium qd and salmeterol bid following 4-week treatment periods in patients with chronic obstructive pulmonary disease (COPD).

  2. Maximum measured concentration of tiotropium in plasma (Cmax) [ Time Frame: 16 weeks ]
  3. Amount of tiotropium that was eliminated in urine (Ae0-8) from time point 0 to 8 hours post-inhalation [ Time Frame: 16 weeks ]
  4. AUC0-∞ of salmeterol in plasma [ Time Frame: 16 weeks ]
  5. Cmax salmeterol in plasma [ Time Frame: 16 weeks ]

Secondary Outcome Measures :
  1. Area under the concentration time curve (AUCt1-t2) of tiotropium and salmeterol in plasma over the time interval t1 to t2 for time intervals 0 to 4, 0 to 6, and 0 to 8 hours after inhalation (AUC0-4, AUC0-6, and AUC0-8) [ Time Frame: 16 weeks ]
  2. Time from dosing to the maximum concentration of tiotropium and salmeterol in plasma (tmax) [ Time Frame: 16 weeks ]
  3. Terminal rate constant in plasma (λz) [ Time Frame: 16 weeks ]
  4. Terminal half-life (t½) of tiotropium and salmeterol in plasma) [ Time Frame: 16 weeks ]
  5. Mean residence time (MRTih) of tiotropium and salmeterol in the body after inhalational administration [ Time Frame: 16 weeks ]
  6. Apparent clearance (CL/F) of tiotropium and salmeterol in plasma after extravascular administration) [ Time Frame: 16 weeks ]
  7. Apparent volume of distribution (Vz/F) during the terminal phase (λz) following an extravascular dose) [ Time Frame: 16 weeks ]
  8. Amount of tiotropium that is eliminated in urine from the time point t1 to time point t2 (Aet1-t2) (Ae0-2, Ae2-4, Ae4-8, Ae0-8) [ Time Frame: 16 weeks ]
  9. Fraction of tiotropium eliminated in urine from time point t1 to time point t2 (fet1-t2) (fe0-2, fe2-4, fe4-8, fe0-8) [ Time Frame: 16 weeks ]
  10. Renal clearance of tiotropium from the time point t1 until the time point t2 (CLR,t1-t2) (CLR,0-2, CLR, 2-4, CLR,4-8, CLR,0-8) [ Time Frame: 16 weeks ]
  11. All adverse events [ Time Frame: 20 weeks ]
  12. Blood pressure (seated) recorded in conjunction with 12-lead ECG recordings pre-dose and following the morning dose of randomized treatment [ Time Frame: 20 weeks ]
  13. Number of patients with abnormalities in routine blood chemistry, haematology and urinalysis [ Time Frame: 16 weeks ]
  14. Trough forced expiratory volume in one second (FEV1) [ Time Frame: 16 weeks ]
  15. Trough forced vital capacity (FVC) [ Time Frame: 16 weeks ]
  16. FEV1 area under the curve 0 to 8 hours (FEV1 AUC0-8h) [ Time Frame: 16 weeks ]
  17. FVC area under the curve 0 to 8 hours (FVC AUC0-8h) [ Time Frame: 16 weeks ]
  18. Individual FEV1and FVC measurements at each time point at the end of each 4-week treatment period. [ Time Frame: 16 weeks ]
