Summary
Ixabepilone is metabolized by CYP3A4, and strong inhibitors can raise its exposure and toxicity. Isoniazid is a weak inhibitor, but both drugs cause peripheral neuropathy and may be hepatotoxic.
What this interaction means in plain words
Isoniazid and Ixabepilone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Possible weak CYP3A4 inhibition and additive neurotoxicity and hepatotoxicity.
What to do
Monitor for neuropathy, neutropenia and liver enzyme elevations, and give pyridoxine with isoniazid. Reduce or delay ixabepilone per labeling if toxicity occurs.
