7 DRUG INTERACTIONS

Strong or Moderate CYP3A Inhibitors

Avoid the concomitant use of strong or moderate CYP3A inhibitors with BOSULIF. Bosutinib is a CYP3A substrate. Concomitant use with a strong or moderate CYP3A inhibitor increases bosutinib Cmax and AUC [see Clinical Pharmacology (12.3)] which may increase the risk of toxicities.

Strong CYP3A Inducers

Avoid the concomitant use of strong CYP3A inducers with BOSULIF. Bosutinib is a CYP3A substrate. Concomitant use with a strong CYP3A inducer decreases bosutinib Cmax and AUC [see Clinical Pharmacology (12.3)] which may reduce BOSULIF efficacy.

Proton Pump Inhibitors (PPI)

As an alternative to PPIs, use short-acting antacids or H2 blockers and separate dosing by more than 2 hours from BOSULIF dosing. Bosutinib displays pH dependent aqueous solubility, Concomitant use with a PPI decreases bosutinib Cmax and AUC [see Clinical Pharmacology (12.3)] which may reduce BOSULIF efficacy.
