Medicinal Product Interactions – Ritonavir with Protease Inhibitors Co-administered Dose of Co- Dose of Medicinal Product AUC Cmin Medicinal Product administered NORVIR Assessed Medicinal (mg) Product (mg) Atazanavir 300 q24h 100 q24h Atazanavir ↑ 86% ↑ 11 fold 1 Atazanavir ↑ 2 fold ↑ 3-7 fold Ritonavir increases the serum levels of atazanavir as a result of CYP3A4 inhibition. Clinical trials confirmed the safety and efficacy of 300 mg atazanavir once daily with ritonavir 100 mg once daily in treatment experienced patients. For further information, physicians should refer to the SmPC for atazanavir. Darunavir 600, single 100 q12h Darunavir ↑ 14 fold Ritonavir increases the serum levels of darunavir as a result of CYP3A inhibition. Darunavir must be given with ritonavir to ensure its therapeutic effect. Ritonavir doses higher than 100 mg twice daily have not been studied with darunavir. For further information, refer to the SmPC for darunavir. Fosamprenavir 700 q12h 100 q12h Amprenavir ↑ 2.4 ↑ 11 fold fold Ritonavir increases the serum levels of amprenavir (from fosamprenavir) as a result of CYP3A4 inhibition. Fosamprenavir must be given with ritonavir to ensure its therapeutic effect. Clinical trials confirmed the safety and efficacy of fosamprenavir 700 mg twice daily with ritonavir 100 mg twice daily. Ritonavir doses higher than 100 mg twice daily 10 have not been studied with fosamprenavir. For further information, physicians should refer to the SmPC for fosamprenavir. Indinavir 800 100 q12h Indinavir2 ↑ 178% ND q12h Ritonavir ↑ 72% ND Ritonavir increases the serum levels of indinavir as a result of CYP3A4 inhibition. Appropriate doses for this combination, with respect to efficacy and safety, have not been established. Minimal benefit of ritonavir-mediated pharmacokinetic enhancement is achieved with doses higher than 100 mg twice daily. In cases of co-administration of ritonavir (100 mg twice daily) and indinavir (800 mg twice daily) caution is warranted as the risk of nephrolithiasis may be increased. Nelfinavir 1250 100 q12h Nelfinavir ↑ ND q12h 20to39% Ritonavir increases the serum levels of nelfinavir as a result of CYP3A4 inhibition. Appropriate doses for this combination, with respect to efficacy and safety, have not been established. Minimal benefit of ritonavir-mediated pharmacokinetic enhancement is achieved with doses higher than 100 mg twice daily. Tipranavir 500 200 q12h Tipranavir ↑ 11 fold ↑ 29 fold q12h Ritonavir ↓ 40% ND Ritonavir increases the serum levels of tipranavir as a result of CYP3A inhibition. Tipranavir must be given with low dose ritonavir to ensure its therapeutic effect. Doses of ritonavir less than 200 mg twice daily should not be used with tipranavir as they might alter the efficacy of the combination. For further information, physicians should refer to the SmPC for tipranavir. ND: Not determined. 1. Based on cross-study comparison to 400 mg atazanavir once daily alone. 2. Based on cross-study comparison to 800 mg indinavir three times daily alone.
