Resumo
Phenelzine inhibits monoamine oxidase and so reduces serotonin breakdown, while cyclobenzaprine is a tricyclic-related muscle relaxant that inhibits serotonin and norepinephrine reuptake. Together this can precipitate serotonin syndrome, with agitation, hyperthermia, clonus and autonomic instability that may be fatal. Hypertensive reactions are also possible with tricyclic agents.
O que esta interação significa em palavras simples
Cyclobenzaprine 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.
Cyclobenzaprine belongs to Musculoskeletal; Phenelzine belongs to Central Nervous System.
Por que acontece
Additive serotonergic activity: irreversible non-selective MAO inhibition plus monoamine reuptake inhibition
O que fazer
Do not combine; allow at least 14 days after stopping the phenelzine before starting cyclobenzaprine, and at least 14 days after stopping cyclobenzaprine before starting the phenelzine.
