Summary
Exemestane is cleared mainly by CYP3A4, and fexinidazole may inhibit this enzyme, which could modestly raise exemestane exposure. The clinical consequence is uncertain, as exemestane has a wide tolerability margin.
What this interaction means in plain words
Exemestane and Fexinidazole 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 CYP3A4 inhibition by fexinidazole reducing exemestane metabolism.
What to do
Monitor for exemestane adverse effects such as hot flashes, arthralgia and fatigue during short fexinidazole courses. No empiric dose change is needed.
