Does Elvitegravir Interact with Elvitegravir Cobicistat Emtricitabine And Tenofovir Disoprox?
Elvitegravir and Elvitegravir Cobicistat Emtricitabine And Tenofovir Disoprox have a unknown drug interaction according to U.S. FDA drug labeling data. Elvitegravir is a modest inducer of CYP2C9 and may decrease the plasma concentrations of CYP2C9 substrates. 7.3 Potential for Other Drugs to Affect One or More Components of STRIBILD Elvitegravir and cobicistat, components of STRIBILD, are metabolized by CYP3A. Drugs that induce CYP3A activity are expected to increase the clearance of elvitegravir and cobicistat, resulting in decreased plasma concentration of cobicistat and elvitegravir, which may lead to loss of therapeutic effect of STRIBILD and development of resistance (Table 5). Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This information is based on official FDA drug labeling sourced from OpenFDA and the NIH National Library of Medicine.
