There may be some dependence on zopiclone, and taking zopiclone may result in physical and psychological dependence, with the risk of dependence increasing with dosage and duration of treatment, and more so in patients with a history of alcohol or drug abuse. Zopiclone belongs to a new class of non-benzodiazepine sedative-hypnotics with sedative, anxiolytic, anticonvulsant and muscle relaxant effects. Compared with other sedative-hypnotics, its action is rapid, with a half-life of about 6 hours, allowing patients to fall asleep faster and maintain sufficient deep sleep, less severe after-effects and hangover than benzodiazepines, with no significant resistance to long-term use, and less addictive than benzodiazepines. Taking zopiclone, the risk of rebound insomnia and withdrawal phenomena after sudden discontinuation cannot be ruled out, especially after long-term treatment, therefore, patients are advised to use the drug under the guidance of a professional physician, and avoid applying or increasing or decreasing the dosage on their own.
