Abstract
|
|
|
The pharmcacokinetic study of epigallocatechin gallate was performed following iv bolus administration in Sprague-Dawley rats. The values of systemic clearance (CL) were 68¡¾5 and 27¡¾1 ml/min/kg following iv bolus administration of 1 mg and 5 mg EGCG, respectively. The values of volume of distribution at steady state were 380 and 835 ml/kg body weight after iv bolus administration 1mg and 5mg EGCG, respectively. The decrease in the value of CL and the increase of Vss as a function of dose suggest saturable pharmacokinetics of EGCG in rats.
