HMG- CoA reduktasehæmmere, som i høj grad er afhængige af CYP3A- metabolisme, f. eks. lovastatin og simvastatin, forventes at få markant øgede plasmakoncentrationer ved samtidig indgift af ritonavir doseret som et antiretroviralt stof eller som en farmakokinetisk forstærker.
HMG-CoA reductase inhibitors which are highly dependent on CYP3A metabolism, such as lovastatin and simvastatin, are expected to have markedly increased plasma concentrations when co-administered with ritonavir dosed as an antiretroviral agent or as a pharmacokinetic enhancer.
