NCT00944437
The aim of this study is to compare two methods of delivery of noninvasive mechanical ventilation (NIV). Since patient compliance and mechanical characteristics of the delivery devices are two fundamental variables in the success of NIV during acute respiratory failure, our hypothesis is that an improved patient-ventilator interface may improve the efficacy of therapy.
NCT00274534
To evaluate changes in PaO2 following inhalation of Tiotropium by HandiHaler compared to Salmeterol MDI in patients with moderate to severe COPD.
NCT00239473
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.
