Inhibitors of the activity of CYP3A4 and CYP2A6 can reduce the metabolism of letrozole and thus increase the concentration of letrozole in the blood plasma. Concomitant use of preparations that strongly inhibit these enzymes (powerful inhibitors of CYP3A4 include, but are not limited to: ketoconazole, itraconazole, voriconazole, ritonavir, clarithromycin, and telithromycin; CYP2A6 (eg, methoxalen)) may increase letrozole exposure. Therefore, patients who are shown potent inhibitors of CYP3A4 and CYP2A6 are advised to exercise caution when using them.
