A Double-blind, Placebo-controlled, Crossover Study to Assess the Effect of Aclidinium Bromide 400 μg Bid on COPD Symptoms and Sleep Quality After 3 Weeks of Treatment in Patients With Stable Moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD)

A Pilot, Double-blind, Placebo-controlled, 2-period Crossover Study to Assess the Effect of Aclidinium Bromide 400 μg Bid on COPD Symptoms and Sleep Quality After 3 Weeks of Treatment in Patients With Stable Moderate-to-severe Chronic Obstructive Pulmonary Disease (COPD)

The purpose of this study is to assess the effect of aclidinium bromide compared with placebo in improving dilatation of the airways (bronchodilation), symptoms of chronic obstructive pulmonary disease (COPD), sleep quality and physical activity after 3 weeks of treatment with aclidinium bromide 400 μg administered twice daily in patients with stable moderate-and-severe COPD.
