Resumo
Benzhydrocodone is a prodrug of hydrocodone, which is metabolised by CYP3A4 to norhydrocodone. Imatinib inhibits CYP3A4, which can raise hydrocodone levels and increase sedation and respiratory depression.
O que esta interação significa em palavras simples
Benzhydrocodone / acetaminophen and Imatinib 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.
Por que acontece
CYP3A4 inhibition by imatinib reduces hydrocodone clearance, with a minor contribution from CYP2D6 inhibition.
O que fazer
Monitor closely for sedation and respiratory depression, and reduce the opioid dose if needed. Take care when imatinib is started or stopped.
