Title: A 6-Month Double-Blind, Double-Dummy, Randomized, Parallel Group, Multicenter Efficacy & Safety Study of SYMBICORT® pMDI 2 x 160/4.5 µg & 80/4.5 µg Bid Compared to Formoterol TBH, Budesonide pMDI (& the Combination) & Placebo in COPD Patients
Brief Summary: The purpose of this study is to compare a combination asthma drug (Symbicort) with its two components, budesonide and formoterol, taken individually or in combination, and with placebo in the long-term maintenance treatment of patients with chronic obstructive pulmonary disease (COPD)
