摘要
Avapritinib is a CYP3A4 substrate, and imatinib is a moderate CYP3A4 inhibitor. Avapritinib exposure may increase, raising risks of cognitive effects, intracranial hemorrhage and edema. Both are kinase inhibitors, and imatinib is also used in GIST, where combination is not typical.
用白話說明這項交互作用的意義
Avapritinib and Imatinib 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.
Avapritinib belongs to Oncology; Imatinib belongs to Oncology.
為什麼會發生
CYP3A4 inhibition by imatinib reduces avapritinib clearance.
處置方式
Avoid the combination if possible. If necessary, use the reduced avapritinib starting dose from labeling and monitor for cognitive effects and bleeding.
