HIDE SMILES / InChI
Clotiazepam is a compound of the benzodiazepine class. The drug was developed in Japan and approved for the treatment of insomnia, anxiety and before anesthesia. Clotiazepam was marketed worlwide under different names, however, currently it is available only in South America under the name Neuroval and presumably in Japan. Clotiazepam exerts its action by binding and activating GABA-A receptors.
