概要
Atazanavir inhibits CYP3A4 and can raise ergotamine concentrations. This risks serious ergot toxicity with peripheral vasospasm and ischemia.
この相互作用をわかりやすく説明すると
Atazanavir and Ergotamine 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.
Atazanavir belongs to Anti Virals; Ergotamine belongs to Central Nervous System.
なぜ起こるのか
CYP3A4 inhibition by atazanavir (usually ritonavir- or cobicistat-boosted) reduces ergotamine clearance.
対処法
Avoid the combination; use a non-ergot alternative for migraine in patients on atazanavir.
