Metabolite Identification
Common NameCarbinoxamine
DescriptionCarbinoxamine, also known as histex PD or histex i-e, belongs to the class of organic compounds known as benzylethers. These are aromatic ethers with the general formula ROCR' (R = alkyl, aryl; R'=benzene). Rather than preventing the release of histamine, as do cromolyn and nedocromil, carbinoxamine competes with free histamine for binding at HA-receptor sites. Carbinoxamine is a first generation antihistamine of the ethanolamine class. Carbinoxamine is a drug which is used for symptomatic relief of seasonal and perennial allergic rhinitis and vasomotor rhinitis, as well as allergic conjunctivitis caused by foods and inhaled allergens. also for the relief of allergic reactions to blood or plasma, and the symptomatic management of mild, uncomplicated allergic skin manifestations of urticaria and angioedema. Carbinoxamine's anticholinergic action appears to be due to a central antimuscarinic effect, which also may be responsible for its antiemetic effects, although the exact mechanism is unknown. Carbinoxamine is a very strong basic compound (based on its pKa). In humans, carbinoxamine is involved in carbinoxamine h1-antihistamine action. Carbinoxamine is a first generation antihistamine that competes with free histamine for binding at HA-receptor sites. Ethanolamine antihistamines have significant antimuscarinic activity and produce marked sedation in most patients. Outside of the human body, Carbinoxamine has been detected, but not quantified in, barley and garden onions. This could make carbinoxamine a potential biomarker for the consumption of these foods. Carbinoxamine is a potentially toxic compound. Carbinoxamine competes with free histamine for binding at HA-receptor sites.

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.
