Etrawiryna i Ewerolimus: interakcja

Strong CYP3A inhibitor and P-gp inhibitor : Avoid coadministration.

Effect of Other Drugs on AFINITOR/AFINITOR DISPERZ Strong or Moderate CYP3A Inhibitor and P-gp Inhibitor Avoid the coadministration of a strong CYP3A inhibitor and P-gp inhibitor [see Dosage and Administration (2.11), Clinical Pharmacology (12.3)] .

Moderate CYP3A inhibitor and P-gp inhibitor : Reduce the dosage as recommended.

Strong CYP3A inducer and P-gp inducer : Increase the dosage as recommended.

Strong CYP3A Inducer and P-gp Inducer Increase the dosage for AFINITOR/AFINITOR DISPERZ with a strong CYP3A inducer and Pg-p inducer as recommended [see Dosage and Administration (2.11), Clinical Pharmacology (12.3)] .

CCR5 antagonists maraviroc ↔ etravirine ↓ maraviroc When Etravirine is co-administered with maraviroc in the absence of a potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor), the recommended dose of maraviroc is 600 mg twice daily.

Antifungals : itraconazole ketoconazole posaconazole ↑ etravirine ↓ itraconazole ↓ ketoconazole ↔ posaconazole Posaconazole, a potent inhibitor of CYP3A4, may increase plasma concentrations of etravirine.

Immunosuppressants : cyclosporine sirolimus tacrolimus ↓ immunosuppressant Etravirine and systemic immunosuppressants should be co-administered with caution because plasma concentrations of cyclosporine, sirolimus, or tacrolimus may be affected.

Therefore, co-administration of Etravirine with drugs that induce or inhibit CYP3A, CYP2C9, and CYP2C19 may alter the therapeutic effect or adverse reaction profile of Etravirine (see Table 4 ) [see Clinical Pharmacology (12.3) ].

…maraviroc/darunavir/ ritonavir The reference for etravirine exposure is the pharmacokinetic parameters of etravirine in the presence of darunavir/ritonavir. ↔ etravirine ↑ maraviroc When Etravirine is co-administered with maraviroc in the presence of a potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor), the recommended dose of maraviroc is 150 mg twice daily.
