Atomoxetine and DAW2022 on OSA Severity

Summary

Obstructive sleep apnea (OSA) is common and has major health implications but treatment options are limited. In previous research atomoxetine and oxybutynin showed promising effect at reducing OSA severity, however they reduced arousal threshold, one of the key traits responsible for OSA. Since oxybutynin was used mainly as a hypnotic, but it is burdened by several anti-cholinergic side effects, DAW2020, a hypnotic which prolonged the total sleep time in a previous trial in OSA patients, could be a better candidate to associate with atomoxetine.
