What happens
Reduced apixaban exposure
Interaction Deep Dive
Concomitant use of apixaban (CYP3A substrate) with a strong CYP3A inducer may significantly reduce apixaban levels1. The manufacturer does not provide specific guidance for coadministration of apixaban with strong CYP3A inducers that are not also P-gp inducers 2, however clinical guidelines suggest to avoid concomitant use or administer cautiously with close monitoring 1.
Why it happens (mechanism)
Induction of CYP3A-mediated metabolism of apixaban
