Abstract: Objective : To search for the optimum formula ratio for the self-emulsifying drug delivery systems of adefovir dipivoxil. Methods : The recipe of the self-emulsifying drug delivery systems of adefovir dipivoxil formation was optimized by studying the pseudo-ternary phase diagram,the self-emulsifying rate,particle size.Adefovir was successfully embedded in the SEDDS emulsion. Results :The optimized prescription was tricaprylin as oil,Cremophor EL35 as surfactant,with the oil and the surfactant ratio was 73. Conclusions :The preliminary adefovir dipivoxil Self-emulsifying prepartion has been prepared.
