Summary
Brief summary
Tiotropium (Spiriva) and formoterol (Oxis) are both currently available prescription medicines for people with COPD. Each of them has a particular effect on the airway. They are usually prescribed independently although it is quite possible for them to be prescribed together. Therefore some people with COPD may already be taking one or both of them. People participating in this study will take a regular dose of tiotropium plus a placebo for 6 weeks and a regular dose of tiotropium plus formoterol for 6 weeks. There will be 2 weeks between each 6 week period when participants will take only tiotropium.
