COPD is a preventable and treatable disease characterized by airflow limitation that is not
fully reversible. The diagnosis of COPD is based on spirometric evidence of airways …

BACKGROUND: The Global Initiative for Chronic Obstructive Lung Disease (GOLD)
recommends the use of forced expiratory volume in 1s (FEV1) to assess airways …

Bronchodilator therapy in COPD is deemed successful if it improves ventilatory mechanics to
a degree where effective symptom alleviation and increased exercise capacity are achieved …

Background: Patients with symptoms of GOLD stage I chronic obstructive pulmonary disease
(COPD) can have significant abnormalities of ventilatory mechanics with greater exertional …

The change in forced expiratory volume in 1 s (FEV 1) after administration of a short-acting
bronchodilator has been widely used to identify patients with chronic obstructive pulmonary …

Partial bronchodilator reversibility can be demonstrated in many patients with stable chronic
obstructive pulmonary disease (COPD), but its relevance to exercise capacity and symptoms …

Background: A limited or absent bronchodilator response is used to classify chronic
obstructive pulmonary disease (COPD) and can determine the treatment offered. The …

Bronchodilators form the foundation of symptomatic treatment of COPD. Several long-acting
bronchodilators are now available for use in COPD, but publications of large-scale studies of …

Background: Although airflow limitation improved by inhaled anticholinergic drugs varies
among individuals with chronic obstructive pulmonary disease (COPD), the relationship …

This retrospective analysis of data from two multi-center, randomized, double-blind, parallel
