How Does Lunesta Work?
Lunesta® (eszopiclone) is a prescription drug approved for the treatment of insomnia. It is used to help people fall asleep and to stay asleep longer. Many people are curious about how it works.
Lunesta 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 has a significant potential for abuse.
The drug has been evaluated in several clinical studies for insomnia. In studies for chronic insomnia, people who took it fell asleep faster and stayed asleep longer than people who did not take Lunesta. Similar results were seen in a study in people with transient insomnia (insomnia that comes and goes).
Also, studies have shown that the medication can cause mild rebound insomnia (worsening of insomnia after stopping a medication). Rebound insomnia symptoms usually occurred for only one night after the drug was stopped, after which people returned to their normal sleeping patterns.
