概要
Idelalisib is a strong CYP3A inhibitor and is expected to markedly increase tolvaptan exposure. Strong CYP3A inhibitors are contraindicated with tolvaptan because of the risk of excessive aquaresis and overly rapid sodium correction.
この相互作用をわかりやすく説明すると
Idelalisib and Tolvaptan 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.
Idelalisib belongs to Oncology; Tolvaptan belongs to Endocrine.
なぜ起こるのか
Idelalisib strongly inhibits CYP3A4, greatly reducing tolvaptan clearance.
対処法
Do not combine; use an alternative to one of the drugs. If idelalisib is essential, withhold tolvaptan.
