Résumé

Posaconazole can substantially increase systemic dihydroergotamine levels after intranasal dosing. This raises the risk of serious vasospastic ischemia of the extremities and central nervous system.

Ce que signifie cette interaction, en termes simples

Dihydroergotamine intranasal and Posaconazole 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.

Niveau de preuve: High

Pourquoi elle survient

Posaconazole strongly inhibits CYP3A4-mediated clearance of dihydroergotamine.

Conduite à tenir

Avoid the combination; it is contraindicated in labeling. Choose a non-ergot acute migraine therapy during posaconazole treatment.
