概要
Cobicistat is a strong CYP3A inhibitor and can substantially increase aprepitant exposure. This may worsen aprepitant adverse effects. Aprepitant in turn may modestly raise levels of other CYP3A substrates in the regimen.
この相互作用をわかりやすく説明すると
Aprepitant and Cobicistat can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Aprepitant belongs to Gastrointestinal Tract; Cobicistat belongs to Miscellaneous.
なぜ起こるのか
Cobicistat strongly inhibits CYP3A4, the main enzyme clearing aprepitant.
対処法
Avoid the combination where possible, or use the single-dose aprepitant regimen with monitoring for adverse effects. Consider an alternative antiemetic such as a 5-HT3 antagonist with dexamethasone adjusted for CYP3A inhibition.
