摘要
Cobicistat inhibits CYP3A4 and CYP2D6, both of which contribute to mexiletine metabolism, so mexiletine levels may increase. This raises the risk of neurologic toxicity and proarrhythmia.
用白話說明這項交互作用的意義
Cobicistat and Mexiletine 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.
Cobicistat belongs to Miscellaneous; Mexiletine belongs to Cardiovascular.
