Taxonomy
DescriptionThis compound belongs to the class of organic compounds known as thienodiazepines. These are heteropolycyclic containing a thiophene ring fused to a diazepine ring. Thiophene is 5-membered ring consisting of four carbon and one sulfur atoms. Diazepine is a 7-membered ring consisting of five carbon and two nitrogen atoms.

Pharmacology
IndicationFor the treatment of anxiety disorders.
PharmacodynamicsClotiazepam is a benzodiazepine derivative possessing anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Stage 2 NREM sleep is significantly increased by clotiazepam.
Mechanism of actionClotiazepam acts at the benzodiazepine receptors (BZD). This agonizes the action of GABA, increasing the frequency of opening of the channel chlorinates and penetration of the ions chlorinates through the ionophore. Increase in membrane polarization decreases the probability of discharge of neurons.
