Resumo
Opioids given with non-selective MAO inhibitors such as phenelzine can lead to serotonin syndrome or to severe CNS depression, hypotension and hyperpyrexia. The reaction is best documented with meperidine, but labeling for morphine advises against use with MAOIs.
O que esta interação significa em palavras simples
Morphine and Phenelzine are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Morphine belongs to Musculoskeletal; Phenelzine belongs to Central Nervous System.
Por que acontece
MAO inhibition potentiates serotonergic and CNS depressant effects of the opioid through mechanisms not fully established for morphine.
O que fazer
Avoid morphine during MAOI therapy and for 14 days after stopping phenelzine; choose a non-opioid or alternative analgesic. If an opioid is unavoidable, use specialist supervision with close monitoring.
