Some less conclusive research also indicated that it had interaction with MAO-B, most likely as an enzyme substrate and not an inhibitor. [6] N,N-DMPEA is a positional isomer of methamphetamine. Instead of the methyl group ...
Opioid-induced hyperalgesia (OIH) or opioid-induced abnormal pain sensitivity, also called paradoxical hyperalgesia, is an uncommon condition of generalized pain caused by the long-term use of high dosages of opioids [1] such as morphine, [2] oxycodone, [3] and methadone. [4] [5] OIH is not necessarily confined to the original affected site. [6]
