The invention belongs to the technical field of medicine, and relates to a self emulsifying drug delivery system of valsartan and a preparation method thereof. The system is composed of valsartan, oil phase, surfactant and cosurfactant, auxiliary ingredients form of liquid or solid (semi) mixed oil, can spontaneously form emulsion in the gastrointestinal tract or at ambient temperature and stirring under mild. The preparation method is as follows: at 20 DEG -50 DEG bath water temperature, the mixture prescription amount of oil, surfactant and co surfactant mixing make clear solution evenly, then add the prescription dose valsartan, stirring to obtain drug dissolution. The invention has the advantages that the self emulsifying drug delivery system of valsartan improves the oral bioavailability of valsartan, and the preparation process is simple and easy to be industrialized.
