Abstract

The most common route of the drug administration is oral route despite the fact that most drugs have low oral aqueous solubility and bioavailability especially for BCS class II and class IV drugs. Many methods have been developed in recent years to overcome the poor solubility and oral bioavailability which includes self-emulsifying drug delivery systems (SEDDS) as one of the approaches. Not only for hydrophobic drugs, but also for hydrophilic compounds with low permeability, bioavailability can be enhanced by self nanoemulsifying drug delivery systems. Recently, a lot of focus and attention has been put in the conversion of liquid SEDDS (L-SEDDS) to solid SEDDS (S-SEDDS) to overcome the limitations of liquid formulations related to their physical and chemical stability, portability, accurate dosing, and limited choices of dosage forms. This article aims to review the formulation components used in SEDDS, various approaches used in the conversion of L-SEDDS to S-SEDDS, their applications, merits, and demerits
