Zopiclone (brand names Imovane, Zimovane, and Dopareel) is a nonbenzodiazepine hypnotic agent used in the treatment of insomnia. Zopiclone is molecularly distinct from benzodiazepine drugs and is classed as a cyclopyrrolone. However, zopiclone increases the normal transmission of the neurotransmitter gamma-aminobutyric acid in the central nervous system, via modulating benzodiazepine receptors in the same way that benzodiazepine drugs do. As zopiclone is sedating, it is marketed as a sleeping pill. It works by causing a depression or tranquilization of the central nervous system. After prolonged use, the body can become accustomed to the effects of zopiclone. When the dose is then reduced or the drug is abruptly stopped, withdrawal symptoms may result. Today, screening and confirmation must still be done by other methods. Screening and confirmation can be performed in one step using GC-MS in the EI, full-scan mode.

The marketing stance for the commercial rollout of Zopiclone (sold as Lunesta) in the United States is that Zopiclone is not addictive. news stories about Lunesta fail to mention it, Zopiclone has been available in Europe and around the world since November 1989. The European brands (Imovane, etc.) contain racemic mixtures and are sold in 5.0 and 7.5 mg dosages. A number of early news reports about the FDA's approval of Zopiclone for sale in the U. under the brand Lunesta included comments that suggested it was "non-addictive" and could be taken safely for long periods of time. However, there is evidence that Zopiclone and the other popular non-benzodiazepine sleep aid Zolpidem both cause tolerance (people increase their dose with regular use) and withdrawal (people report substantial difficulty sleeping or other side effects when stopping after regular use). It is possible that there is a lower risk of addiction because of the difference in dose and isomers, but this remains to be seen as the general public in the U. The Jan 25, 2005 Washington Post story about the approval stated, with a hint of ironic disbelief: It sounds like an insomniac's dream: a sleeping pill that can be taken for weeks or even months at a time, without the risk of addiction or morning-after grogginess. Unlike other sleeping pills, including market leader Ambien, which are not supposed to be taken for longer than 10 days at a time, Lunesta has no FDA-recommended time limit. product, Lunesta, is being sold in 1, 2, and 3 milligram tablets of just the S-isomer (they have named this eszopiclone), which is considered to be the primary active isomer.

And when its use was stopped "cold turkey," according to Dr. Andrew Krystal, who ran one of the trials at Duke University, researchers found few to none of the symptoms withdrawal including delirium and a worsening of symptoms insomnia that patients sometimes experience when discontinuing other prescription sleep aids. [Source: LA Times, 17 January 2005] However, the official literature produced by the pharmaceutical company and the FDA both include mentiones of tolerance and withdrawal, although they are clearly presented as negligible.
