Safety Information
Zopiclone Usage And Synthesis
  • DescriptionZopiclone 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).

  • DescriptionZopiclone 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.
