Metabolite Identification
Common NameHydroxyethylpromethazine
DescriptionHydroxyethylpromethazine belongs to the class of organic compounds known as phenothiazines. These are polycyclic aromatic compounds containing a phenothiazine moiety, which is a linear tricyclic system that consists of a two benzene rings joined by a para-thiazine ring. In humans, hydroxyethylpromethazine is involved in the hydroxyethylpromethazine h1-antihistamine action pathway. Hydroxyethylpromethazine is a primary metabolite. Primary metabolites are metabolically or physiologically essential metabolites. They are directly involved in an organism’s growth, development or reproduction. Based on a literature review very few articles have been published on Hydroxyethylpromethazine.
