Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended.

Drug Interactions with Strong Cytochrome P450 3A4 Inhibitors The use of strong cytochrome P450 3A4 (CYP3A4) inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with Fluticasone Propionate DISKUS is not recommended because increased systemic corticosteroid adverse effects…

The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with Fluticasone Propionate DISKUS is not recommended because increased systemic corticosteroid adverse effects may occur.

Ritonavir A drug interaction trial with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a strong CYP3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] .

Inhibitors of Cytochrome P450 3A4 Fluticasone propionate is a substrate of CYP3A4.

If either is abnormal, consider prophylactic use of systemic steroids (1-2 mg/kg) for one to two weeks concomitantly with Gleevec at the initiation of therapy.

In these instances, Gleevec was resumed at a dose lower than that at which the reaction occurred and some patients also received concomitant treatment with corticosteroids or antihistamines.

The condition was reported to be reversible with the administration of systemic steroids, circulatory support measures and temporarily withholding Gleevec.
