Metabolite Identification
Common NameTriprolidine
DescriptionTriprolidine is only found in individuals that have used or taken this drug. It is the first generation histamine H1 antagonist used in allergic rhinitis; asthma; and urticaria. It is a component of cough and cold medicines. It may cause drowsiness. [PubChem]Triprolidine 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.
