The purpose of this study is to evaluate the hypnotic efficacy of ezopiclone in subjects with mild to moderate OSAS.

Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. This study will compare the use of eszopiclone to placebo for subjects with mild to moderate obstructive sleep Apnea syndrome (OSAS). Frequency and duration of apnea and hypopnea episodes, oxygen saturation, objective sleep parameters and safety information will be collected in this study.
