概要
Rilpivirine is a CYP3A4 substrate, and repeated dexamethasone dosing may reduce its concentrations, raising the risk of virologic failure and NNRTI resistance. Single-dose dexamethasone is not a concern.
この相互作用をわかりやすく説明すると
Dexamethasone and Rilpivirine 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.
Dexamethasone belongs to Endocrine; Rilpivirine belongs to Anti Virals.
なぜ起こるのか
Dexamethasone induces CYP3A4, increasing rilpivirine clearance.
対処法
Do not use more than a single dose of systemic dexamethasone with rilpivirine; select an alternative corticosteroid or antiretroviral for longer courses.
