Treadmill Endurance During 2-Year Treatment With Tiotropium in Patients With COPD: A Randomized Trial.
Disease progression in COPD is associated with a decline in exercise performance over time. We assessed whether tiotropium might mitigate this by determining its effect on treadmill endurance time (ET) over 2 years. ⋯ Treadmill ET was numerically greater over 2 years with tiotropium vs placebo. However, the 96-week difference was not statistically significant. Spirometry and health status also improved with tiotropium over 2 years, attesting to the benefits of long-acting bronchodilator therapy.
