概要
Cobicistat is a potent CYP3A4 inhibitor and may increase etoposide exposure. This can worsen myelosuppression, mucositis and other cytotoxic toxicity.
この相互作用をわかりやすく説明すると
Elvitegravir / cobicistat / emtricitabine / tenofovir df and Etoposide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
なぜ起こるのか
Cobicistat inhibits CYP3A4 and P-glycoprotein, reducing etoposide metabolism and clearance.
対処法
Prefer an antiretroviral regimen without a pharmacokinetic booster during etoposide therapy. If unavoidable, monitor blood counts closely and consider etoposide dose reduction.
