概要
Conivaptan is a CYP3A4 substrate and itraconazole is a strong CYP3A4 inhibitor, so conivaptan exposure rises markedly. This may cause excessively rapid sodium correction with risk of osmotic demyelination.
この相互作用をわかりやすく説明すると
Conivaptan and Itraconazole 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.
なぜ起こるのか
Strong CYP3A4 inhibition by itraconazole reduces conivaptan clearance.
対処法
Do not combine. Use another hyponatremia treatment, and avoid conivaptan for about two weeks after stopping itraconazole.
