Animal experiment:

Cats[1]Effects of various agents (e.g., Chlormezanone 300 mg/kg i.p.) are studied on linguomandibular, extensor and patellar reflexes in spinal cats.

Chlormezanone resembles benzodiazepine. The action of Chlormezanone is similar to benzodiazepine-type agents. Chlormezanone is used as an anxiolytic and a muscle relaxant.

Comparative results obtained with Chlormezanone in the dosage levels capable of producing more than 80% depression in the contralateral extensor[1].
