Brief Summary:
  1. To compare the systemic drug exposure of 100 μg Serevent ® Diskus ® with that of 50 μg Serevent ® MDI with sufficient precision so that in combination with a second trial it can be demonstrated that the systemic drug exposure of a new formulation of salmeterol xinafoate is not superior to that of Serevent ® MDI
  2. To test a system of ordered null hypotheses regarding the exposure of two dose levels of Serevent ® Diskus ® and Serevent ® MDI
  3. To get data about the systemic drug exposure of 25 μg Serevent ® MDI and of 50 μg Serevent ® Diskus ®

Secondary Outcome Measures :
  1. AUC0-tz (area under the concentration-time curve of the analyte in plasma over the time interval from 0 to the time of the last quantifiable data point) [ Time Frame: Up to 6 hours after drug administration ]
  2. AUCt1-t2 (Area under the concentration time curve of the analyte in plasma over the time interval t1 to t2) [ Time Frame: Up to 6 hours after inhalation ]
  3. tmax (time from dosing to the maximum concentration of the analyte in plasma) [ Time Frame: Up to 6 hours after drug administration ]
  4. λz (terminal rate constant in plasma) [ Time Frame: Up to 6 hours after drug administration ]
  5. t½ (terminal half-life of the analyte in plasma) [ Time Frame: Up to 6 hours after drug administration ]
  6. MRTinh (mean residence time of the analyte in the body after inhalational administration) [ Time Frame: Up to 6 hours after drug administration ]
  7. CL/F (apparent clearance of the analyte in the plasma after extravascular administration) [ Time Frame: Up to 6 hours after drug administration ]
  8. Vz/F (apparent volume of distribution during the terminal phase λz following an extravascular dose) [ Time Frame: Up to 6 hours after drug administration ]
  9. Aet1-t2 (amount of analyte that was eliminated in urine from the time interval t1 to t2) [ Time Frame: Up to 6 hours after inhalation ]
  10. fet1-t2 (fraction of administered drug excreted unchanged in urine from time point t1 to t2) [ Time Frame: Up to 6 hours after inhalation ]
  11. CLR,t1-t2 (renal clearance of the analyte in plasma from the time point t1 to t2) [ Time Frame: Up to 6 hours after inhalation ]
  12. Number of participants with abnormal findings in physical examination [ Time Frame: Up to 15 days after last drug administration ]
  13. Number of participants with clinically significant changes in vital signs [ Time Frame: Up to 15 days after last drug administration ]
  14. Number of participants with abnormal findings in ECG [ Time Frame: Up to 15 days after last drug administration ]
  15. Number of participants with abnormal changes in clinical laboratory parameters [ Time Frame: Up to 15 days after last drug administration ]
  16. Number of participants with adverse events [ Time Frame: Up to 15 days after last drug administration ]
