Summary
Erythromycin inhibits CYP3A4 and P-gp and may increase paclitaxel exposure. Paclitaxel is mainly cleared via CYP2C8 with a minor CYP3A4 role, so the effect is probably modest.
What this interaction means in plain words
Erythromycin lactobionate and Paclitaxel 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.
Erythromycin lactobionate belongs to Anti Bacterial; Paclitaxel belongs to Oncology.
Why it happens
CYP3A4 and P-gp inhibition by erythromycin reduces paclitaxel clearance.
