Abstract: Objective : To study the pharmacokinetics of self-emulsifying drug delivery systems of adefovir dipivoxil in rats. Methods : Six SD rats were randomly divided into two groups for oral administration of the self-emulsifying adefovir dipivoxil and adefovir dipivoxil tablets at a single dose of 100 mg/kg.HPLC method was applied to determine the plasma concentration of these two groups.The calculations of pharmacokinetic parameters were performed with 3P87 program. Results :For the self-emulsifying adefovir dipivoxil,Cmax and AUC were 2.509 4 μg/mL and 277.291 1 μg·min/mL,respectively;while for adefovir sipivoxil tablet,Cmax and AUC were 1.725 8 μg/mL and 215.919 6 μg·min/mL,respectively. Conclusions :The oral bioavailability of the self-emulsifying adefovir dipivoxil was better than tadefovir dipivoxil tablet.
