Metabolite Identification
Common NameTolpropamine
DescriptionTolpropamine, also known as pragman, 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. Tolpropamine is a drug. Tolpropamine is a very strong basic compound (based on its pKa). In humans, tolpropamine is involved in tolpropamine h1-antihistamine action. Tolpropamine is an antihistamine and anticholinergic used as an antipruritic.
