Dynamic Hyperinflation and Tiotropium
This study is currently recruiting participants.
Verified by Gelb, Arthur F., M.D., August 2008
Sponsors and Collaborators: Gelb, Arthur F., M.D.
Boehringer Ingelheim Pharmaceuticals
Pfizer
Information provided by: Gelb, Arthur F., M.D.
ClinicalTrials.gov Identifier: NCT00569270
  Purpose

We will detect dynamic hyperinflation (DH)in 40 COPD patients with moderately severe disease using metronome paced hyperventilation (MPH) with inspiratory capacity as the primary end point. Hypothesis: Is tiotropium capable of lung volume protecting inspiratory capacity from MPH induced DH vs placebo in a randomized crossover double blinded study.


Condition Intervention Phase
COPD
Drug: tiotropium
Drug: placebo
Phase IV

Drug Information available for: Tiotropium Tiotropium bromide
U.S. FDA Resources
Study Type: Interventional
Study Design: Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Active Control, Crossover Assignment, Efficacy Study
Official Title: Simplified Detection of Dynamic Hyperinflation Using Metronome Paced Hyperventilation and the Effect of Tiotropium in Patients With COPD

Further study details as provided by Gelb, Arthur F., M.D.:
