خلاصه

Clarithromycin inhibits CYP3A4 and P-glycoprotein, which may increase exposure to irinotecan and its active metabolite SN-38 by diverting it away from inactive pathways. This may worsen neutropenia and diarrhea.

معنای این تداخل به زبان ساده

Clarithromycin and Irinotecan 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.

Clarithromycin belongs to Anti Bacterial; Irinotecan belongs to Oncology.

سطح شواهد: Moderate

چرا رخ می‌دهد
