Can a simple inhaler boost exercise in COPD patients with overinflated lungs?
NCT ID NCT04994574
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a combination inhaler (tiotropium/olodaterol) can improve exercise capacity in people with COPD who have overinflated lungs. 44 adults used the inhaler for 4 weeks, and researchers measured changes in oxygen use during exercise, heart function, and quality of life. The goal was to see if the treatment helps patients breathe easier and be more active.
