Continuous Positive Airway Pressure, Arousability and Links to Mechanisms in Obstructive Sleep Apnea
Recruiting now · Phase 3 · Has a placebo group
Conditions studied: Sleep Apnea, Obstructive Sleep Apnea
In brief
The study design is a randomized, controlled clinical trial to test the hypothesis that arousal threshold (ArTH) will affect how individuals with obstructive sleep apnea (OSA, Apnea-Hypopnea Index (AHI) of 10/hour of higher) respond to CPAP therapy regarding adherence and cognitive function (executive function). Investigators hypothesize that raising ArTH with eszopiclone will improve adherence to CPAP and neurocognitive function with CPAP therapy. Investigators also hypothesize that a lower baseline ArTH is associated with worse CPAP adherence, while a higher baseline ArTH is associated with improved neurocognitive outcomes with CPAP therapy.

- History of motor vehicle accidents related to sleepiness and/or motor vehicle "near misses" (e.g. sleepiness during driving or lane changes)
- Severe hepatic impairment (liver function tests 2 X the upper limit of normal)
- Unstable medical condition (e.g., decompensated heart failure, end-stage chronic obstructive pulmonary disease, end-stage renal disease)
