Gender differences in pharmacokinetics of oral warfarin in rats.
Gender different pharmacokinetics of warfarin were investigated after oral administration at a dose of 2 mg/kg to male and female rats. The concentrations of warfarin in rat plasma were analysed by the HPLC method. Noncompartmental analysis was used for the calculation of the total area under the plasma concentration-time curve from time zero to time infinity (AUC) and terminal half-life of warfarin. After oral administration of warfarin to female rats, the AUC was significantly greater (345 compared with 180 microg h/ml) than that in male rats.
