Résumé

Phenelzine inhibits monoamine oxidase and so reduces serotonin breakdown, while desipramine is a tricyclic antidepressant that blocks norepinephrine reuptake and, to a lesser degree, serotonin 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.

Ce que signifie cette interaction, en termes simples

Desipramine 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.

Desipramine belongs to Central Nervous System; Phenelzine belongs to Central Nervous System.

Niveau de preuve: High

Pourquoi elle survient

Additive serotonergic activity: irreversible non-selective MAO inhibition plus monoamine reuptake inhibition

Conduite à tenir
