Atazanavir ve Suzetrijin etkileşimi

• when coadministered with drugs that are strong inducers of CYP3A due to the potential for loss of therapeutic effect and development of resistance.

• Coadministration with drugs that are strong inducers of CYP3A, due to the potential for loss of therapeutic effect and development of resistance.

Initiation of medications that inhibit or induce CYP3A may increase or decrease concentrations of REYATAZ with ritonavir, respectively.

Potential for Other Drugs to Affect REYATAZ Atazanavir is a CYP3A4 substrate; therefore, drugs that induce CYP3A4 may decrease atazanavir plasma concentrations and reduce REYATAZ’s therapeutic effect ( see Table 16 ).

Corticosteroids: dexamethasone and other corticosteroids (all routes of administration) ↓ atazanavir ↑ corticosteroids Coadministration with dexamethasone or other corticosteroids that induce CYP3A may result in loss of therapeutic effect of REYATAZ and development of resistance to atazanavir and/or ritonavir.
