概要
Ketoconazole markedly raises venetoclax exposure, increasing the risk of tumor lysis syndrome and neutropenia. It is contraindicated during the initial ramp-up phase.
この相互作用をわかりやすく説明すると
Ketoconazole 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.
Ketoconazole belongs to Anti Fungals; Venetoclax belongs to Miscellaneous.
なぜ起こるのか
Strong CYP3A4 inhibition (and P-gp inhibition) reduces venetoclax clearance.
対処法
Avoid during ramp-up. After ramp-up, reduce the venetoclax dose by at least 75% and monitor for toxicity.
