ABSTRACT
One promising strategy for improving the oral bioavailability of medications that are not very water soluble is the use of self-emulsifying drug delivery systems, or SEDDS. SEDDS increase drug solubilization, absorption, and overall therapeutic efficacy by forming fine oil-in-water emulsions when the gastrointestinal tract is mildly agitated. These systems reduce first-pass metabolism by facilitating lymphatic transport and avoiding the dissolution step, which is frequently a rate-limiting factor in oral drug delivery. For stable emulsification and drug loading, formulation ingredients like oils, surfactants, and co-surfactants are essential. For increased stability, patient compliance, and commercial viability, SEDDS can be further optimized in solid dosage forms (such as tablets and capsules). In conclusion, SEDDS present a flexible and effective delivery system for hydrophobic medications and have a great deal of promise for further pharmaceutical advancement. Therefore, the present review work has been done to give an insight of lipid-based carriers in self-emulsifying systems.
