Metabolite Identification
Common NameDimethindene
DescriptionDimethindene is only found in individuals that have used or taken this drug. It is an antihistamine/anticholinergic used orally and locally as an antipruritic.Dimethindene is a selective histamine H1 antagonist and binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.

Enzymes

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
In peripheral tissues, the H1 subclass of histamine receptors mediates the contraction of smooth muscles, increase in capillary permeability due to contraction of terminal venules, and catecholamine release from adrenal medulla, as well as mediating neurotransmission in the central nervous system
Gene Name:
HRH1
Uniprot ID:
P35367
Molecular weight:
55783.6

General function:
Involved in G-protein coupled receptor protein signaling pathway
Specific function:
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is adenylate cyclase inhibition
