Summary

Strong CYP3A inducers markedly reduce bosutinib exposure, and enzalutamide is expected to do the same. This may result in loss of leukemia disease control.

What this interaction means in plain words

Bosutinib and Enzalutamide 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.

Bosutinib belongs to Oncology; Enzalutamide belongs to Endocrine.

Evidence level: High

Why it happens

Enzalutamide induces CYP3A4, increasing the metabolism of bosutinib.

What to do

Avoid the combination; labeling recommends against strong CYP3A inducers with bosutinib. Use an alternative to enzalutamide where possible.
