Zopiclone - is a non-benzodiazepine hypnotic drug (Z-drugs) used as for insomnia treatment. Available in pharmacies under the brand name Imovane, Somnol, Piklodorm. Non-benzodiazepine hypnotic of new generation with minimal effect on sleep structure.

Zopiclone causes benzodiazepines-like changes in EEG and sleep architecture, and also causes sleep disturbances after discontinuation of its use, as relapse effect. The group of non-benzodiazepine hypnotics include its full analogs namely Sonata, and Lunesta, but they don’t offer any advantages and are quite rare.

In the process of accommodation, active metabolites are formed: N-oxide zopiclone and N-demethyl zopiclone, the identification of which helps to establish the cause of suicide committer's death. Zopiclone became a favorite drug of drug addicts for its ‘mix’ compilation. Let’s say a human is in a weakened physical state, that means that a dose of 90 mg may be the minimum lethal dose of zopiclone.

It doesn’t provoke postsomnic violations: no feeling of weakness and drowsiness the next morning. Readmission of zopiclone is not accompanied by accumulation. Zopiclone exerts less side effects than most traditional hypnotic drugs.
