Official title

Investigating the Effects of Symbicort on the Ventilatory Kinematics in Patients With Obstructive Disease With Optoelectronic Plethysmography

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to investigate how budesonide/formoterol fumarate dihydrate (Symbicort ©) affects dynamic hyperinflation in patients with obstructive disease using Optoelectronic Plethysmography (OEP). This study is unique as it will be the first randomized, doubleblind, crossover study with a placebo inhaler and budesonide/formoterol fumarate dihydrate as the intervention which will evaluate the effects on ventilatory mechanics through the use of OEP. The investigators plan to demonstrate that budesonide/formoterol fumarate dihydrate impacts dynamic hyperinflation which can be detected with OEP, and that budesonide/formoterol fumarate dihydrate may have an effect in the short term on exercise capacity during a constant load exercise test. The changes in ventilatory mechanics measured after budesonide/formoterol fumarate dihydrate by OEP will provide a unique evaluation of budesonide/formoterol fumarate dihydrate in a controlled setting also demonstrating the utility of OEP in evaluating of the effects of a medical treatment on hyperinflation in individuals with chronic obstructive lung disease (COPD). 1. Primary Objective/Hypothesis: Our objective is to measure baseline, post treatment and post exercise spirometry and evaluate exercise dynamic hyperinflation before and after treatment using OEP. The investigators hypothesize that budesonide/formoterol fumarate dihydrate will decrease dynamic hyperinflation as measured by OEP. 2. Primary Endpoint: Our primary endpoint is the change in dynamic hyperinflation, specifically end expiratory volumes, dynamic lung volumes and diaphragmatic paradoxical breathing as measured by OEP. 3. Secondary Objective: Our secondary objective is to evaluate duration of steady state exercise and exercise capacity before and after treatment. Our secondary hypothesis is that decreases in dynamic hyperinflation during exercise will lead to improvements in dyspnea with exercise, and allow for increases in exercise capacity. 4. Secondary endpoint: Exercise time, change in Borg scale at rest vs. Borg scale at steady state vs. Borg at end exercise.
