Zopiclone Usage And Synthesis
Zopiclone is an agonist at the type A γ-aminobutyric acid (GABA) receptor. It is a non-benzodiazepine hypnotic which was first reviewed in Drugs in 1986 and it is indicated for short-term treatment of insomnia. Zopiclone has a relatively low propensity to cause residual clinical effects (such as difficulty in waking or reduced morning concentration).

Zopiclone is an effective hypnotic agent with a short duration of action. Although it interacts with the benzodiazepine receptor complex, it is reported to have minimal effects on memory, little synergy with alcohol, and low abuse potential.
Cyclopyrrolone member of a family of non-benzodiazepine GABAA receptor agonists. This is a controlled substance (depressant) in the US but not in Canada. Sedative, hypnotic

Zopiclone was introduced as a sedative in 1985. It remains registered in several countries and the World Health Organization is not aware of any other country that has refused registration.
