摘要
Ketoconazole markedly raises dihydroergotamine concentrations. This can cause severe peripheral and cerebral vasospasm and ischemia, including limb and bowel ischemia, and is a labeled contraindication.
用白話說明這項交互作用的意義
Dihydroergotamine and Ketoconazole 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.
Dihydroergotamine belongs to Central Nervous System; Ketoconazole belongs to Anti Fungals.
為什麼會發生
Strong inhibition of CYP3A4 by ketoconazole reduces the first-pass and systemic metabolism of dihydroergotamine.
處置方式
Do not combine. Use a non-ergot migraine treatment, or an antifungal that does not strongly inhibit CYP3A4, if dihydroergotamine is needed.
