Inspiratory Flow Rates Achieved by the COPD Patients Through Breezhaler®, Ellipta® and Handihaler® Inhaler Devices

No active drug or placebo were administered to patients during this study. Each patient were required to inhale via all three (03) study devices (Breezhaler®, Ellipta® and Handihaler®). Each patient was required to produce at least three (03) inhalational profiles via each inhalational device, following the training and demonstration for correct inhalational procedure, for each device.
