Atazanavir ve Flutikazon ve salmeterol etkileşimi

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)] .

Inhibitors of Cytochrome P450 3A4 Fluticasone propionate and salmeterol, the individual components of this product, are substrates of CYP3A4.

Inhaled beta agonist: salmeterol ↑ salmeterol Coadministration of salmeterol with REYATAZ is not recommended.

Coadministration of fluticasone propionate and REYATAZ with ritonavir is not recommended unless the potential benefit to the patient outweighs the risk of systemic corticosteroid side effects [see Warnings and Precautions (5.1) ] .

Concomitant use of salmeterol and REYATAZ may result in increased risk of cardiovascular adverse reactions associated with salmeterol, including QT prolongation, palpitations, and sinus tachycardia.

Inhaled/nasal steroid: fluticasone REYATAZ ↑ fluticasone Concomitant use of fluticasone propionate and REYATAZ without ritonavir should be used with caution.

Consider alternatives to fluticasone propionate, particularly for long-term use.
