The effects of silybinin, an antioxidant, on the pharmacokinetics of tamoxifen and its metabolite, 4-hydroxytamoxifen, were investigated in rats. A single dose of tamoxifen was administered intravenously (2 mg/kg) and orally (10 mg/kg) without or with silybinin (0.5, 2.5 and 10 mg/kg) to rats. Silybinin significantly altered the pharmacokinetics of orally administered tamoxifen.
