Interaksi Flutikason dan salmeterol dan Vorikonazol

Avoid strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): May increase risk of systemic corticosteroid and cardiovascular effects.

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/Salmeterol MDPI is not recommended because increased systemic corticosteroid and…

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

Ritonavir : Fluticasone Propionate: 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/Salmeterol MDPI continues, but at times therapy with Fluticasone Propionate/Salmeterol MDPI may need to be interrupted.

• 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.
