概要
Rifampicin strongly induces CYP3A and can markedly lower ensitrelvir plasma concentrations. Subtherapeutic exposure may cause loss of antiviral activity and treatment failure.
この相互作用をわかりやすく説明すると
Ensitrelvir and Rifampicin 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; Rifampicin belongs to Anti Bacterial.
なぜ起こるのか
Rifampicin induces CYP3A (and transporters), accelerating ensitrelvir metabolism and lowering exposure.
対処法
Do not co-administer; select an alternative COVID-19 antiviral not affected by strong inducers. If rifampicin is essential, avoid ensitrelvir.
