DESCRIPTION
Pyrilamine maleate salt is a first generation antihistamine and binds with high affinity to G(q/11) protein. It is commonly utilized as a radioligand binding assay for the H1 receptor. It also has anticholinergic properties. It is used in over-the-counter combination products to treat the common cold and menstrual symptoms. It is also the active ingredient of the topical antihistamine creams Anthisan and Neoantergan. It is also found to be a potent inhibitor of CYP2D6 in hepatocytes. It has been listed.
