Beta-meprodin
Very little modern clinical data exist. Early 1950s human studies suggested β-meprodine is roughly equipotent to, or slightly less potent than, morphine by weight, while its stereoisomer α-meprodine is several-fold stronger. Because β-meprodine is Schedule I in the United States and internationally controlled, it is almost never encountered outside of research or illicit synthesis. All meperidine-type opioids can precipitate serotonin syndrome when combined with MAOIs or high-dose serotonergic drugs. Fatal respiratory depression has been reported at therapeutic doses in opioid-naive subjects.
