التداخل بين أرمودافينيل وإلفيتيغرافير وكوبيسيستات وإمتريسيتابين وتينوفوفير

Strongly induce CYP3A, which may lead to lower exposure of one or more components and loss of efficacy of GENVOYA and possible resistance.

Drugs that induce CYP3A activity are expected to increase the clearance of elvitegravir and cobicistat, resulting in decreased plasma concentration of cobicistat, elvitegravir, and TAF, which may lead to loss of therapeutic effect of GENVOYA and development of resistance (see Table 5 ).

Corticosteroids: e.g., betamethasone budesonide ciclesonide dexamethasone fluticasone methylprednisolone mometasone prednisone triamcinolone ↓ elvitegravir ↓ cobicistat ↑ corticosteroids Coadministration with oral dexamethasone or other systemic corticosteroids that induce CYP3A may result in loss of therapeutic effect and development of resistance to elvitegravir.

Drugs that induce CYP3A can alter the concentrations of one or more components of GENVOYA.

TAF is not an inhibitor or inducer of CYP3A in vivo .
