Resumo
Dihydroergotamine is cleared mainly by CYP3A4, and strong inhibition of this enzyme can raise ergot levels sharply, causing ergotism with severe peripheral and cerebral vasospasm and ischemia. Miconazole is a CYP3A4 inhibitor and, although vaginal absorption is low, systemic exposure can occur and ergot toxicity is potentially catastrophic.
O que esta interação significa em palavras simples
Dihydroergotamine and Miconazole can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Dihydroergotamine belongs to Central Nervous System; Miconazole belongs to Anti Fungals.
Por que acontece
Miconazole inhibits CYP3A4-mediated metabolism of dihydroergotamine, increasing its systemic concentrations.
O que fazer
Avoid the combination where possible, and prefer a topical antifungal with minimal absorption or an alternative to the ergot. If used together, counsel the patient to report numbness, cold or painful extremities, or chest pain immediately.
