Interactions with Strong Cytochrome P450 3A4 Inhibitors Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with ketoconazole, and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) because adverse effects related to…

• Strong Cytochrome P450 3A4 Inhibitors (e.g., ritonavir): Use with caution.

After oral administration of ketoconazole, a strong inhibitor of CYP3A4, the mean plasma concentration of orally administered budesonide increased.

Caution should be exercised when considering the co-administration of PULMICORT FLEXHALER with long-term ketoconazole and other known strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) [see Warnings and Precautions (5.7) ] .

Inhibitors of Cytochrome P450 3A4 The main route of metabolism of corticosteroids, including budesonide, is via cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4).

Corticosteroids (systemic): cortisone/hydrocortisone dexamethasone ↑ corticosteroids (systemic) Concomitant administration with systemic corticosteroids whose exposures are significantly increased by CYP3A inhibitors can increase the risk for Cushing's syndrome and adrenal suppression.

Alternative corticosteroids to dexamethasone should be considered, particularly for long-term use.
