Design and optimization of a new self-nanoemulsifying drug delivery system

Abstract. To improve the dissolution rate of ibuprofen, a model poorly water soluble drug, self-nanoemulsifying drug delivery systems (SNEDDS) were developed. Various surfactants and oils were screened as candidates for SNEDDS on the basis of droplet size of the resulting emulsions. The influence of the constituent structure, concentration and the composition of SNEDDS formulations, and the…
