概要
Phenobarbital is expected to lower doravirine exposure considerably, risking virologic failure and resistance. Labeling contraindicates strong CYP3A inducers with doravirine.
この相互作用をわかりやすく説明すると
Doravirine and Phenobarbitone 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.
Doravirine belongs to Anti Virals; Phenobarbitone belongs to Central Nervous System.
なぜ起こるのか
Phenobarbital induces CYP3A4, accelerating doravirine metabolism.
対処法
Avoid the combination and use an alternative anticonvulsant or antiretroviral regimen. Allow for the long duration of enzyme induction after stopping phenobarbital before starting doravirine.
