How Does Eszopiclone Work?
Eszopiclone is part of a class of medications called sedative/hypnotics, which are known more commonly as sleep medicines. Like many other sleep medications, it is a controlled substance and may be abused.
Eszopiclone has been evaluated in several clinical studies for
insomnia. In studies for
chronic insomnia, people who took eszopiclone fell asleep faster and stayed asleep longer than people who did not take eszopiclone. Similar results were seen in a study of eszopiclone in people with transient insomnia (insomnia that comes and goes).
Also, studies have shown that eszopiclone can cause mild rebound insomnia (worsening of insomnia after stopping a medication). Rebound
insomnia symptoms usually occurred for only one night after eszopiclone was stopped, after which people returned to their normal sleeping patterns.
