Interaksi Etravirin dan Lopinavir dan ritonavir

Etravirine and atazanavir/ritonavir can be co-administered without dose adjustments. atazanavir/cobicistat ↓ atazanavir ↓ cobicistat Co-administration of Etravirine with atazanavir/cobicistat is not recommended because it may result in loss of therapeutic effect and development of resistance to atazanavir. darunavir/ritonavir ↓ etravirine The mean systemic exposure…

Because all subjects in the Phase 3 trials received darunavir/ritonavir as part of the background regimen and etravirine exposures from these trials were determined to be safe and effective, Etravirine and darunavir/ritonavir can be co-administered without dose adjustments. darunavir/cobicistat ↓ cobicistat darunavir: effect unknown Co-administration of Etravirine…

Co-administration of Etravirine and fosamprenavir without low-dose ritonavir is not recommended. fosamprenavir/ritonavir ↑ amprenavir Due to a significant increase in the systemic exposure of amprenavir, the appropriate doses of the combination of Etravirine and fosamprenavir/ritonavir have not been established.

Co-administration of Etravirine and fosamprenavir/ritonavir is not recommended. indinavir (without ritonavir) ↓ indinavir Concomitant use of Etravirine with indinavir without low-dose ritonavir may cause a significant alteration in the plasma concentration of indinavir.

Co-administration of Etravirine and indinavir without low-dose ritonavir is not recommended. lopinavir/ritonavir ↓ etravirine The mean systemic exposure (AUC) of etravirine was reduced after co-administration of Etravirine with lopinavir/ritonavir (tablet).

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

Patients who exhibit these signs or symptoms should be evaluated and KALETRA and/or other antiretroviral therapy should be suspended as clinically appropriate.

Elevated transaminases with or without elevated bilirubin levels have been reported in HIV-1 mono-infected and uninfected patients as early as 7 days after the initiation of KALETRA in conjunction with other antiretroviral agents.

Antimycobacterial: rifampin ↓ lopinavir Contraindicated due to potential loss of virologic response and possible resistance to KALETRA or to the class of protease inhibitors or other co-administered antiretroviral agents [see Contraindications ( 4 )] .

Drugs with No Observed or Predicted Interactions with KALETRA Drug interaction or clinical studies reveal no clinically significant interaction between KALETRA and desipramine (CYP2D6 probe), etravirine, pitavastatin, pravastatin, stavudine, lamivudine, omeprazole, raltegravir, ranitidine, or rilpivirine.
