摘要
Itraconazole increases venetoclax exposure and risks tumor lysis syndrome during dose initiation, as well as neutropenia and other toxicities. The risk is greatest during the ramp-up phase.
用白話說明這項交互作用的意義
Itraconazole and Venetoclax 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.
Itraconazole belongs to Anti Fungals; Venetoclax belongs to Miscellaneous.
為什麼會發生
Strong CYP3A4 inhibition (and P-glycoprotein inhibition) by itraconazole reduces venetoclax clearance.
處置方式
Do not use during venetoclax initiation and ramp-up; after ramp-up, reduce the venetoclax dose by at least 75% per labeling and monitor for toxicity and blood counts.
