Metabolite Identification
Common NamePhenindamine
DescriptionPhenindamine is an antihistamine. Phenindamine blocks the effects of the naturally occurring chemical histamine in your body. Antihistamines such as phenindamine appear to compete with histamine for histamine H1- receptor sites on effector cells. The antihistamines antagonize those pharmacological effects of histamine which are mediated through activation of H1- receptor sites and thereby reduce the intensity of allergic reactions and tissue injury response involving histamine release. It is used to treat sneezing, runny nose, itching, watery eyes, hives, rashes, itching, and other symptoms of allergies and the common cold. Symptoms of a phenindamine overdose include extreme sleepiness, confusion, weakness, ringing in the ears, blurred vision, large pupils, dry mouth, flushing, fever, shaking, insomnia, hallucinations, and possibly seizures.

Chemical Taxonomy
Description Belongs to the class of organic compounds known as indenes and isoindenes. Indenes and isoindenes are compounds containing an indene moiety(which consists of a cyclopentadiene fused to a benzene ring), or a isoindene moiety (which consists of a cyclopentadiene fused to cyclohexadiene ring).

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
