Self-emulsifying drug delivery system (SEDDS), a category of lipid-based technology, has gained interest in the recent years for enhancement of solubility and bioavailability of poorly water-soluble drugs. With the progress of research in this field, novel excipients have been developed with enhanced properties. But excipient selection is the key hurdle in the formulation of SEDDS. The objective of this review is to summarize different types of oils, surfactants, co-surfactants which are the key components of liquid SEDDS (L-SEDDS), various carriers utilized in the conversion of L-SEDDS to solid SEDDS (S-SEDDS), their description, properties, grades, and applications in pharmacy. This article provides an overview of solidification techniques to transform L-SEDDS to S-SEDDS which are more stable and have better patience compliance. This review presents numerous literature reports on various excipients used and the discussion on how these excipients affect the final results.
