Pharmacology
Indication For the treatment of anxiety disorders.
Pharmacodynamics Clotiazepam is a benzodiazepine derivative possessing anxiolytic, anticonvulsant, sedative and skeletal muscle relaxant properties. Stage 2 NREM sleep is significantly increased by clotiazepam.
Mechanism of action Clotiazepam 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.
