Airway Clearance Study

January 21, 2011 updated by: AstraZeneca

A Randomized, Double-blind, Two-way Cross-over Study Evaluating Systemic Bioavailability and Airway Clearance of SymbicortTurbuhaler 320/9mcg vs SeretideDiskus 50/500mcg After Single Inhalations in Patients With COPD and Healthy Volunteers

The purpose of the study is to evaluate how the airways in COPD patients, compared to healthy volunteers, absorb steroid drugs from Symbicort Turbuhaler and Seretide Diskus. The blood concentrations of the steroids will be used as surrogate marker.
