Official title
The Role of Endorphins in the Perception of Dyspnea With Resistive Loading in Patients With COPD
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Endorphins are released in response to breathing difficulty and can modify the perception of breathlessness. In this randomized placebo-controlled trial, resistive breathing loads are used to provoke breathlessness in patients with chronic obstructive pulmonary disease. The hypothesis of the study is that intravenous (IV) administration of naloxone, a medication which blocks endorphin activity, will increase the perception of breathlessness experienced by patients while breathing through a resistance device, compared with IV administration of normal saline.
