Liphophilic formulations of pharmaceuticals are very promising methods of drug solubility improvement. Four types of the formulations are available: Self-emulsifying drug delivery systems (SEDDS) consist of oils, surfactants and cosolvents where the pharmaceutical ingredient are dissolved. These systems form o/w emulsions which can be administered in tablets, soft or hard gelatin capsules. The effectivity of SEDDS depends on many parameters, such as excipients or emulsion droplet size.
