Assessment of the Safety and Ability of a Once-a-day Dose of an Orally Inhaled Medicine [ie, Glycopyrrolate Inhalation Solution = GIS] to Improve Airflow in the Lungs When Delivered With an Electronic eFlow Nebulizer System in Patients With Chronic Obstructive Pulmonary Disease (COPD)

The study assessed the safety and ability of several doses of an orally inhaled medicine \[ie, Glycopyrrolate Inhalation Solution = GIS\] to improve airflow in the lungs when delivered with an electronic eFlow nebulizer system in patients with Chronic Obstructive Pulmonary Disease (COPD). The study was conducted in 12 patients in 2 parts. Part 1 was designed to find the once-a- day GIS dose that produced the highest improvement in lung airflow. Part 2 tested the GIS dose with the highest improvement in lung airflow and a placebo (ie, no drug) delivered by a general purpose nebulizer. The airflow improvements of the same GIS dose were compared between the two nebulizer systems to determine what effect the device had on GIS delivery.
