Metabolite Identification
Common NameN-Desmethyltramadol
DescriptionN-Desmethyltramadol, also known as M2, belongs to the class of organic compounds known as anisoles. These are organic compounds containing a methoxybenzene or a derivative thereof. N-Desmethyltramadol is a very strong basic compound (based on its pKa). N-Desmethyltramadol is a metabolite of tramadol. The drug has a wide range of applications, including treatment of rheumatoid arthritis, restless legs syndrome, and fibromyalgia. Within humans, N-desmethyltramadol participates in a number of enzymatic reactions. In particular, N-desmethyltramadol and formaldehyde can be biosynthesized from tramadol through its interaction with the enzymes cytochrome P450 2B6 and cytochrome P450 3A4. In addition, N-desmethyltramadol can be converted into N,N-didesmethyltramadol and formaldehyde through its interaction with the enzymes cytochrome P450 2B6 and cytochrome P450 3A4. In humans, N-desmethyltramadol is involved in tramadol metabolism pathway. Tramadol hydrochloride (trademarked as Conzip, Ryzolt, Ultracet, Ultram in the USA; Ralivia and Zytram XL in Canada) is a centrally-acting synthetic analgesic used to treat moderate to moderately-severe pain. It was launched and marketed as Tramal by the German pharmaceutical company Grnenthal GmbH in 1977 (Wikipedia ).
