Metabolite Identification
Common NameLofentanilum
DescriptionLofentanilum belongs to the class of organic compounds known as fentanyls. Fentanyls are compounds containing the fentanyl moiety or a derivative, which is based on a N-(1-(2-phenylethyl)-4-piperidinyl)-N-phenylpropanamide skeleton. Based on a literature review very few articles have been published on Lofentanilum. This compound has been identified in human blood as reported by (PMID: 31557052 ). Lofentanilum is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Lofentanilum is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
