Résumé

Isocarboxazid irreversibly inhibits monoamine oxidase, so serotonin is not broken down, and maprotiline is a tetracyclic antidepressant that blocks noradrenaline reuptake. Together they can precipitate serotonin syndrome with hyperthermia, agitation, clonus and autonomic instability, which can be fatal.

Ce que signifie cette interaction, en termes simples

Isocarboxazid and Maprotiline 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.

Isocarboxazid belongs to Central Nervous System; Maprotiline belongs to Central Nervous System.

Niveau de preuve: High

Pourquoi elle survient

Excess serotonergic activity (MAO inhibition plus serotonin reuptake or receptor effects)

Conduite à tenir

Do not co-administer. Leave at least 14 days after stopping isocarboxazid before starting maprotiline, and at least 14 days after stopping maprotiline before starting isocarboxazid.
