摘要
Cobicistat is a potent CYP3A4 inhibitor and may increase etoposide exposure. This can worsen myelosuppression, mucositis and other cytotoxic toxicity.
用白話說明這項交互作用的意義
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.
為什麼會發生
Cobicistat inhibits CYP3A4 and P-glycoprotein, reducing etoposide metabolism and clearance.
處置方式
Prefer an antiretroviral regimen without a pharmacokinetic booster during etoposide therapy. If unavoidable, monitor blood counts closely and consider etoposide dose reduction.
