摘要
Levoketoconazole is a strong CYP3A4 inhibitor that increases ribociclib exposure, and both drugs prolong the QT interval. Ribociclib may also modestly raise levoketoconazole levels, so arrhythmia risk is substantially increased.
用白話說明這項交互作用的意義
Levoketoconazole and Ribociclib are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Levoketoconazole belongs to Endocrine; Ribociclib belongs to Oncology.
為什麼會發生
CYP3A4 inhibition raising ribociclib exposure combined with additive QTc prolongation.
處置方式
Avoid the combination, and consider alternative therapy for either drug. If a strong inhibitor is unavoidable, reduce ribociclib to 400 mg daily with close ECG and electrolyte monitoring.
