概要
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.
この相互作用をわかりやすく説明すると
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.
なぜ起こるのか
Strong inhibition of CYP3A4 by ketoconazole reduces the first-pass and systemic metabolism of dihydroergotamine.
対処法
Do not combine. Use a non-ergot migraine treatment, or an antifungal that does not strongly inhibit CYP3A4, if dihydroergotamine is needed.
