O que dizem as bulas da FDA
Da bula de Fluticasona (FLUTICASONE PROPIONATE DISKUS) · em vigor desde 2026-05-14
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 )] .
When such an infection develops, it should be treated with appropriate local or systemic (i.e., oral) antifungal therapy while treatment with Fluticasone Propionate DISKUS continues, but at times therapy with Fluticasone Propionate DISKUS may need to be interrupted.
Da bula de Voriconazol (Voriconazole) · em vigor desde 2026-06-02
• Adrenal Dysfunction : Carefully monitor patients receiving voriconazole and corticosteroids (via all routes of administration) for adrenal dysfunction both during and after voriconazole treatment.
Patients receiving voriconazole and corticosteroids (via all routes of administration) should be carefully monitored for adrenal dysfunction both during and after voriconazole treatment.
Monitor for potential adrenal dysfunction when voriconazole is administered with other corticosteroids [see Warnings and Precautions (5.8) ].
Adrenal insufficiency has been reported in patients receiving azoles with or without concomitant corticosteroids.
In patients receiving azoles without corticosteroids adrenal insufficiency is related to direct inhibition of steroidogenesis by azoles.
