Summary

Ketoconazole may increase daunorubicin exposure, potentially worsening myelosuppression, mucositis and cardiotoxicity. The clinical data are limited and the effect is mainly predicted from transporter inhibition.

What this interaction means in plain words

Daunorubicin and Ketoconazole 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.

Daunorubicin belongs to Oncology; Ketoconazole belongs to Anti Fungals.

Evidence level: Low

Why it happens

Ketoconazole inhibits P-glycoprotein, which mediates efflux and elimination of daunorubicin.

What to do

Monitor blood counts and signs of cardiotoxicity, and consider an antifungal with less transporter inhibition during chemotherapy.
