Study of Pain Processing in Subjects Suffering From Obstructive Sleep Apnea
Trial ID: NCT00672737
We would like to test the effect of opioid medication on pain sensitivity in subjects who have been diagnosed with a sleep disorder called Obstructive Sleep Apnea (OSA) compared to other subjects without OSA. Patients with OSA may have an altered sensitivity to the sedative, analgesic, and respiratory depressant effects of opioids.
