Official title
Efficacy of Inhaling Bronchodilator Medications in Patients With Chronic Obstructive Pulmonary Disease Who Have a Low Peak Inspiratory Flow Rate
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Some patients with Chronic Obstructive Pulmonary Disease (COPD) report that they are uncertain whether they achieve clinical benefit using a dry-powder inhaler (DPI). One possible explanation is that the patient is unable to inhale the dry powder bronchodilator medication into the lower respiratory tract due to a low peak inspiratory flow rate (PIFR). A PIFR \< 60 l/min is considered to be suboptimal flow for a DPI, including the Diskus device. The hypothesis of the study is that the forced expiratory volume in 1 second (FEV1) measured at two hours after inhalation of the study medication will be higher with arformoterol solution (15 mcg) from a nebulizer compared with salmeterol dry powder (50 mcg) inhaled from the Diskus.
