title: Effects of naringin on the pharmacokinetics of intravenous paclitaxel in rats.
abstract: It was reported that paclitaxel is an inhibitor of hepatic P-glycoprotein (P-gp) and hepatic microsomal cytochrome P450 (CYP) 3A1/2, and that naringin is an inhibitor of biliary P-gp and CYP3A1/2 in rats. The purpose of this study was to report the effects of oral naringin on the pharmacokinetics of intravenous paclitaxel in rats. Oral naringin (3.3 and 10 mg/kg) was pretreated 30 min before intravenous (3 mg/kg) administration of paclitaxel. After intravenous administration of paclitaxel, the AUC was significantly greater (40.8% and 49.1% for naringin doses of 3.3 and 10 mg/kg, respectively), and Cl was significantly slower (29.0% and 33.0% decrease, respectively) than controls. The significantly greater AUC could be due mainly to an inhibition of metabolism of paclitaxel via CYP3A1/2 by oral naringin. The inhibition of hepatic P-gp by oral naringin could also contribute to the significantly greater AUC of intravenous paclitaxel by oral naringin.
