Zopiclone is a nonbenzodiazepine hypnotic agent used for the short-term management of insomnia, particularly for adults experiencing difficulties with sleep initiation or maintenance. Classified as a cyclopyrrolone, zopiclone acts by binding to the benzodiazepine site of the GABA-A receptor complex, enhancing the effect of the neurotransmitter GABA and promoting sedative, anxiolytic, anticonvulsant, and muscle relaxant effects. Despite having a distinct chemical structure, zopiclone produces its therapeutic actions by increasing GABAergic inhibition in the central nervous system, much like benzodiazepines, and thereby supports healthy sleep architecture with minimal next-day residual effects. Short-term use is emphasized due to potential risks of dependence and withdrawal with prolonged administration.
