Study Summary

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. OSA patients show a marked reduction in upper airway (UA) dilator muscle activity at sleep onset and this phenomenon leads to increased collapsibility of UA compared to normal subjects. Until recently, the search for medicines to activate pharyngeal muscles in sleeping humans has been discouraging. However, exciting new animal research has shown that drugs with noradrenergic and antimuscarinic effects can restore pharyngeal muscle activity to waking levels. In this protocol the investigators will test the effect of atomoxetine (a norepinephrine reuptake inhibitor) and oxybutynin (an antimuscarinic drug) administered together on OSA phenotype traits and OSA severity during sleep.

Primary Outcome

Based on previous studies the investigators anticipate that Atomoxetine and Oxybutynin will reduce AHI more effectively in subjects with moderate sleep apnea, mildly obese (BMI\<32), Vpassive \> 50% of Veupnea (ventilation during eupneic ventilatory drive), low muscle compensation (Vactive - Vpassive \<1 L/min)
