TITLE: Double-blinded, Double-dummy, Study Comparing Fluticasone-salmeterol to Placebo in Patients With COPD and Associated Poor Sleep or Daytime Somnolence.

Detailed Summary

Fluticasone (Advair), an inhaled corticosteroid and salmeterol, a long-acting beta agonist, are approved for use in the management of COPD. Fluticasone/salmeterol has been shown to significantly improve forced expiratory volume (FEV1) and decrease COPD symptoms (Calverley et al. 2003, 2007). Inhaled corticosteroids have been shown to decrease frequency of COPD exacerbations (Gartlehner et al. 2006) and long acting bronchodilators demonstrated a reduction in dyspnea, increased airflow and reduction in hyperinflation in patients with symptomatic COPD (Ramirez-Venegas et al. 1997). Specifically, salmeterol has also been shown to have a positive effect on symptoms and health status of patients with COPD when added to usual treatment (Stockley et al. 2006). Previous research of subjects from our group with asthma has shown salmeterol to be associated with sustained improvements in morning peak expiratory flow (PEF), protection from nighttime lung function deterioration and improvement in patient perception of sleep (Wiegand et al. 1999). This study has not been performed in patients with COPD nor has the effect of salmeterol with fluticasone on sleep quality been assessed. AIM: The aim of this study is to determine the effect of fluticasone/salmeterol on sleep quality in patients with COPD and to compare efficacy of Advair 250 compared to placebo on sleep. The hypothesis is that there would be a significant improvement in sleep quality when patients are placed on fluticasone/salmeterol as compared to placebo.
