Mitotane is a strong CYP3A4 inducer that persists for weeks after discontinuation and can substantially lower exemestane concentrations. Reduced exposure may compromise the antiestrogenic effect of treatment.
用白話說明這項交互作用的意義

為什麼會發生
Mitotane induces CYP3A4, accelerating the metabolism of exemestane.
處置方式
