A randomised, double-blind, double dummy, 3 way cross-over study evaluating the effects of SERETIDE™ 50/500mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg alone and SERETIDE 50/500mcg alone) in the treatment of subjects with COPD
This study was designed to evaluate the effects on lung function of a combination of SERETIDE 50/500mcg twice daily plus tiotropium bromide 18mcg once daily compared with the individual treatments (tiotropium bromide 18mcg once daily alone and SERETIDE 50/500mcg twice daily alone) in subjects with COPD. The study will utilise a three-way cross-over design with a 2-week wash-out period between each 2-week consecutive treatment period.
