Metabolite Identification
Common NameLoperamide
DescriptionLoperamide, also known as imodium or diamide, 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. Loperamide is a drug which is used for the control and symptomatic relief of acute nonspecific diarrhea and of chronic diarrhea associated with inflammatory bowel disease or gastroenteritis. also used for reducing the volume of discharge from ileostomies. Loperamide is a very strong basic compound (based on its pKa).
