Amprenavir was previously indicated for the treatment of HIV-1 infection in combination with other antiretroviral agents. Vitamin E supplementation may have been included for antioxidant support and potential immune benefits. Note: Amprenavir has been discontinued and is no longer available as a commercial product.
Amprenavir works by inhibiting HIV protease, an enzyme essential for viral replication and the production of infectious viral particles. Vitamin E acts as a fat-soluble antioxidant, helping to protect cells from oxidative damage and supporting overall immune function.
This formulation is no longer available commercially. Patients currently on HIV therapy should use currently approved antiretroviral medications as prescribed by their healthcare provider. Vitamin E supplementation should be discussed with a doctor, as high doses may increase bleeding risk, particularly in individuals on anticoagulant therapy or with vitamin K deficiency. Always take HIV medications exactly as prescribed and never share antiretrovirals with others.
