Common Namepentazocine
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. pentazocine is found in Papaver somniferum. pentazocine was first documented in 2022 (PMID: 36000113). Based on a literature review a small amount of articles have been published on (+)-Pentazocine (PMID: 35928702) (PMID: 35910816) (PMID: 35754470) (PMID: 35745593).
