Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

This will be a prospective randomized double-blinded parallel group clinical trial evaluating the short-term effects of theophylline therapy on exercise duration and lung function in patients with chronic obstructive pulmonary disease already receiving both tiotropium and a long-acting beta-agonist (salmeterol or formoterol).

The purpose of this study is to determine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease.

Dyspnea (shortness of breath) is a complex experience that includes interpretation of physical impairments and associated distress to the person. The role of mind-body interactions in the experience of the symptom of dyspnea suggests that complementary and alternative medicine (CAM) therapies may be effective in abating dyspnea and improving patients' health-related quality of life. CAM strategies work in a number of ways that are directly applicable to dyspnea, such as decreasing the stress response, inducing relaxation, and facilitating a less distressful interpreted experience of physical disorders. We have combined a number of established CAM approaches aimed at breath-centered mindfulness and relaxation into an single therapy, mind-body breathing therapy (MBBT). The purpose of this study is to test the efficacy of MBBT in improving dyspnea and health-related quality of life for patients with emphysema (chronic obstructive pulmonary disease).

The primary objective was to compare the bronchodilator efficacy of two doses (5 mcg and 10 mcg) of tiotropium inhalation solution delivered by the Respimat inhaler once daily to placebo and to ipratropium bromide MDI four times daily in patients with COPD. The secondary objective was to compare the safety of tiotropium inhalation solution delivered by the Respimat to placebo and ipratropium bromide MDI.

To compare the efficacy and safety of tiotropium plus formoterol in comparison to salmeterol plus fluticasone in COPD patients.

To evaluate the long-term safety and monitor the long-term efficacy of arformoterol over a period of 6 months in subjects with chronic obstructive pulmonary disease (COPD).

The aim of the study is to investigate the effect of roflumilast (APTA-2217) on lung function in patients with chronic obstructive pulmonary disease (COPD). Roflumilast will be administered orally once daily. The study duration consists of a baseline period (4 weeks) and a treatment period (24 weeks). The study will provide further data on safety, tolerability, and effectiveness of roflumilast.

This study compares the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease). This study will last up to 18 weeks, and subjects will visit the clinic 5 times. Subjects will be given breathing tests, and will record their breathing symptoms daily on diary cards.

The purpose of this study is to determine which dose of the investigational drug is the most safe and effective for the treatment of COPD compared to the control drug

The purpose of this study is to evaluate the safety, tolerability and efficacy of repeated inhalative doses of Bimosiamose on ozone induced sputum neutrophilia in healthy subjects.
