Cyclopyrrolones

Cyclopyrrolones are a family of hypnotic and anxiolytic nonbenzodiazepine drugs with similar pharmacological profiles to the benzodiazepine derivatives.

Although cyclopyrrolones are chemically unrelated to benzodiazepines, they function via the benzodiazepine receptor/GABA neurotransmitter. The best known cyclopyrrolone derivatives are zopiclone (Imovane®) and its enantiomer eszopiclone (Lunesta®), which are used to treat insomnia, and have a known potential for abuse. Other cyclopyrrolone derivatives include suriclone, pagoclone, pazinaclone and suproclone.
