Metabolite Identification
Common NameDiphenylpyraline
DescriptionDiphenylpyraline, also known as difenilpiralina or lergobine, belongs to the class of organic compounds known as diphenylmethanes. Diphenylmethanes are compounds containing a diphenylmethane moiety, which consists of a methane wherein two hydrogen atoms are replaced by two phenyl groups. Diphenylpyraline (DPP; sold as Allergen, Arbid, Belfene, Diafen, Hispril, Histyn, Lergobine, Lyssipol, Mepiben, Neargal) is a first-generation antihistamine with anticholinergic effects of the diphenylpiperidine class. DPP has also been found to act as a dopamine reuptake inhibitor and produces hyperactivity in rodents. Diphenylpyraline is a drug which is used for use in the treatment of allergic rhinitis, hay fever, and allergic skin disorders. It has been shown to be useful in the treatment of Parkinsonism. Diphenylpyraline is a very strong basic compound (based on its pKa). In humans, diphenylpyraline is involved in diphenylpyraline h1-antihistamine action. Diphenylpyraline is a potentially toxic compound. It is marketed in Europe for the treatment of allergies.
