WebThe metabolites of ITZ have been predicted to account for ~50% of the overall CYP3A4 inhibition in vivo. This prediction is based on in vivo disposition data of ITZ and its three metabolites after a 100-mg dose of ITZ. 8 However, the inhibitory metabolites of ITZ, namely hydroxy-ITZ (OH-ITZ), keto-ITZ (keto-ITZ), and N-desalkyl ITZ (ND-ITZ ...
