Metabolite Identification
Common NameClotiazepam
DescriptionClotiazepam is only found in individuals that have used or taken this drug. It is a benzodiazepine derivative, not approved for sale in the U.S. or Canada, but has been approved in the U.K. It is a schedule IV drug in Canada.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.

Enzymes

General function:
Involved in monooxygenase activity
Specific function:
Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It performs a variety of oxidation reactions (e.g. caffeine 8-oxidation, omeprazole sulphoxidation, midazolam 1'-hydroxylation and midazolam 4-hydroxylation) of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics. Acts as a 1,8-cineole 2-exo-monooxygenase. The enzyme also hydroxylates etoposide.
