概要
Phenytoin is expected to lower ensitrelvir exposure significantly, risking inadequate antiviral effect. Labeling contraindicates strong CYP3A inducers with ensitrelvir.
この相互作用をわかりやすく説明すると
Ensitrelvir and Phenytoin 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.
Ensitrelvir belongs to Anti Virals; Phenytoin belongs to Central Nervous System.
なぜ起こるのか
Phenytoin induces CYP3A4, increasing ensitrelvir clearance.
対処法
Avoid coadministration and use an alternative COVID-19 antiviral not affected by induction. Use a non-inducing anticonvulsant if the patient's seizure management allows.
