摘要
Erythromycin raises dihydroergotamine concentrations, which can cause ergotism with severe peripheral and cerebral vasospasm and ischemia. Cases of limb and organ ischemia have been reported with CYP3A4 inhibitors and ergots.
用白話說明這項交互作用的意義
Dihydroergotamine and Erythromycin lactobionate 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; Erythromycin lactobionate belongs to Anti Bacterial.
為什麼會發生
Erythromycin inhibits CYP3A4-mediated metabolism of dihydroergotamine.
處置方式
Do not use together; choose a non-macrolide antibiotic such as one without CYP3A4 inhibition, or another migraine therapy.
