QOSA: Effects of Quetiapine on Sleep and Next Day Alertness in People With Obstructive Sleep Apnea
Study Details
Study Description
Brief Summary
Quetiapine is medication used to treat schizophrenia and bipolar disorder. Increasingly, low doses of quetiapine are prescribed "off-label" for insomnia. Quetiapine increases sleep duration with fewer interruptions, and people report feeling more rested. This accounts for why it is popular to prescribe for insomnia. Insomnia and obstructive sleep apnea (OSA) share many symptoms and differential diagnosis can be difficult. While quetiapine may improve sleep and breathing in certain people (i.e in light sleepers) an initial study indicated that quetiapine caused breathing disturbances in healthy individuals. Effects in OSA are unknown. In this placebo-controlled double blind study, participants with mild-moderate OSA will spend 2 nights in the sleep lab, one with quetiapine at a dose commonly prescribed for insomnia and one with placebo. The investigators will assess participants sleep by standard clinical sleep study, and morning alertness using questionnaires, reaction tests, and a driving simulator test.

- Change in perceived sleepiness (Quetiapine night vs. placebo night) [Next morning following two non-consecutive single night sleep studies (Quetiapine night vs. placebo night) up to one month apart.]
Next day perceived sleepiness assessed via the Karolinska Sleepiness Scale (10 point scale where 1=extremely alert and 10=extremely sleepy)
- Change in driving simulator performance (Quetiapine night vs. placebo night) [Next morning following two non-consecutive single night sleep studies (Quetiapine night vs. placebo night) up to one month apart.]
Next day alertness as measured via the AusEd driving simulator performance task
- Change in psycho-motor vigilance (Quetiapine night vs. placebo night) [Next morning following two non-consecutive single night sleep studies (Quetiapine night vs. placebo night) up to one month apart.]
