The purpose of this study is to determine the effect of treatment with tiotropium bromide on efficiency of gas exchange and exercise performance in COPD subjects during exercise.
The purpose of this study is to examine whether breathing helium-hyperoxia during exercise in a pulmonary rehabilitation program can improve the exercise tolerance and health related quality of life of patients with Chronic Obstructive Pulmonary Disease (COPD).
Patients with COPD experience exacerbations that are a major cause of morbidity. Exacerbations are associated with increased airway and systemic inflammation and those experiencing frequent exacerbations demonstrate increased inflammation in the stable state. Tiotropium has been shown to reduce exacerbation frequency and it might be postulated that this is due to a reduction in inflammation. The study will compare airway inflammation and exacerbation frequency in patients with COPD on tiotropium or placebo.
The main objective of the study is to evaluate the predictive factors of the endothelial function to the waning of an acute exacerbation in COPD. It will act to do a multivariate analysis to determine the respective weight of the parameters of the systemic inflammation, of the oxidative stress of the functional respiratory parameters and then functional respiratory parameters. In exacerbated Chronic Obstructive Pulmonary Disease (COPD) patients, there is augmentation of hypoxia and the obstructive ventilatory disorders is more important. This is correlated with an increase in C-reactive Protein (CRP) and of inflammatory cytokines and oxidative stress. It has been demonstrated that there is an endothelial dysfunction in answer to hypoxia. Since the exacerbated COPD patients are hypoxic in most cases , we suppose they have an endothelial dysfunction during exacerbation. So we think we will find an augmentation of vascular resistances ,shown by a peripheral arterial tone too high. And this, certainly, play a part in physiopathology of the COPD exacerbation.
The purpose of this study is to evaluate the level of satisfaction experienced by asthma or chronic obstructive pulmonary disease (COPD) patients when using the Fluticasone/Salmeterol HFA Metered Dose Inhaler (MDI) with counter, as compared to using Fluticasone/Salmeterol HFA MDI without counter.
The study was designed to obtain data about the efficacy and safety of 3 doses of indacaterol (150, 300, and 600 µg) in Japanese patients with chronic obstructive pulmonary disease (COPD) so that optimal dose(s) could be chosen for testing in later studies.
The purpose of the study is to determine the appropriate dose of fluticasone propionate/formoterol fumarate that is closest to Advair Diskus (fluticasone propionate/salmeterol xinafoate using pulmonary function, safety, and levels of study drug in blood plasma in patients with chronic obstructive pulmonary disease.
The primary objective of this study is to compare the effect of ipratropium bromide/salbutamol inhalation spray combination administered by the Respimat® inhaler (20 mcg/100 mcg), ipratropium bromide inhalation spray administered by the Respimat® inhaler (20 mcg), and COMBIVENT® MDI administered q.i.d on FEV1 at intervals over a treatment period of 12 weeks in patients with COPD. Specifically, non-inferiority of Combivent Respimat® to COMBIVENT® MDI in FEV1 AUC from 0 to 6 hours , superiority of Combivent Respimat® to Atrovent Respimat® monotherapy in FEV1 AUC from 0 to 4 hours, and non-inferiority of Combivent Respimat® to Atrovent Respimat® monotherapy in FEV1 AUC from 4 to 6 hours will be analyzed. In addition, steady state pharmacokinetics over one dosing interval following 4 weeks of therapy will be characterized in a subgroup of patients.
The study is designed to obtain safety and efficacy data on three dose levels of indacaterol when delivered via an SDDPI in patients with COPD. All patients will receive 1 day of treatment with each of the following: indacaterol 150 µg, once- indacaterol 300 µg, indacaterol 600 µg, placebo, and formoterol. Each treatment day will be followed by a washout-period of 1 week.
