Eszopiclone (Lunesta), a new hypnotic

Abstract

Eszopiclone (Lunesta) is effective for treatment of insomnia for at least 6 months, with no evidence of tolerance, dependence or abuse. It has caused mild, transient memory impairment in some patients. No studies are available comparing eszopiclone with similar drugs like zolpidem (Ambien) or zaleplon (Sonata).
