| Common Name | Chlormezanone |
|---|
| Description | Chlormezanone is only found in individuals that have used or taken this drug. It is a non-benzodiazepine that is used in the management of anxiety. It has been suggested for use in the treatment of muscle spasm. [PubChem]Chlormezanone binds to central benzodiazepine receptors which interact allosterically with GABA receptors. This potentiates the effects of the inhibitory neurotransmitter GABA, increasing the inhibition of the ascending reticular activating system and blocking the cortical and limbic arousal that occurs following stimulation of the reticular pathways. |
