Formoterol-HFA 3-month Study in Chronic Obstructive Pulmonary Disease (COPD) Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to demonstrate the clinical equivalence of formoterol-HFA pMDI 12µg/actuation administered twice daily to formoterol DPI 12µg/capsule delivered by the Aerolizer inhaler and administered twice daily in patients with COPD.

Detailed Description
-----------------
Phase III, multicenter, multinational, double-blind, double-dummy, randomised, 2-arm parallel-group, 3-month study in patients with stable COPD. Comparison in terms of efficacy and safety of the two formulations of formoterol administered as 24µg/day in a bid regimen
