Metabolite Identification
Common Name(+)-Pentazocine
Description(+)-Pentazocine, also known as fortral or lexir, belongs to the class of organic compounds known as 2,6-dimethyl-3-benzazocines. These are aromatic compounds containing a 6,7-benzomorphan skeleton, which is substituted by methyl group at the 2- and 6-positions. Based on a literature review a significant number of articles have been published on (+)-Pentazocine. This compound has been identified in human blood as reported by (PMID: 31557052 ). (+)-pentazocine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically (+)-Pentazocine 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.
