Randomized Controlled Trial Multicenter Study Comparative StudySafety and efficacy of the once-daily anticholinergic BEA2180 compared with tiotropium in patients with COPD.
To determine the safety and efficacy of BEA2180, an anticholinergic agent in patients with chronic obstructive pulmonary disease (COPD). ⋯ All study doses of BEA2180 improved lung function, reduced symptoms and exacerbations, and improved health status in COPD; all treatments were well tolerated. Clinical trial identifier: NCT00528996.

Multicenter StudyResting and ADL-induced dynamic hyperinflation explain physical inactivity in COPD better than FEV1.
Physical activity and health status deteriorate early in the course of chronic obstructive pulmonary disease (COPD). This can only partially be explained by the degree of airflow limitation. Changes in (resting and dynamic) lung volumes are known to be associated with functional impairments and thus might influence physical activity level. The aim of the present cross-sectional study was to explore the contribution of dynamic hyperinflation during daily life activities (ADL) in the decline in physical activity. ⋯ The presence of resting hyperinflation and occurrence of dynamic hyperinflation during ADL contribute to reduced physical activity levels in patients with COPD, independently of the degree of airflow limitation.
