Amprenavir (the active metabolite of<unk> , which is found in blood plasma, liver and other organs) is metabolized via the liver enzyme CYP3A4 and also weakly inhibits this enzyme. This means that combination with drugs that are also metabolized by CYP3A4 can increase their plasma concentrations and thus side effects; and combination with drugs that inhibit CYP3A4 can increase amprenavir concentrations. When combining<unk>  with low doses of the CYP3A4 inhibitor ritonavir, this interaction is intended as it allows for application of lower<unk>  doses.
