REVOLUTIONIZING PHARMACEUTICALS: A DEEP DIVE INTO SELF NANO EMULSIFYING DRUG DELIVERY SYSTEMS

From nearly a decade’s time, there has been an increased inclination with respect to nanoemulsions owing to their augmented and ameliorated characteristics in comparison to conventional methods of drug delivery. Self-nano-emulsifying drug delivery systems (SNEDDS) have substantiated their effectiveness in enhancing the solubility and bioavailability of poorly soluble substances. These systems, often isotropic mixtures, consist of oils, surfactants, and cosurfactants/cosolvents. They possess the capability to create nanoemulsions or fine oil-in-water (o/w) emulsions with mild stirring and dilution by the water phase along the gastrointestinal tract. This system has proven its worth in enhancing the absorption of lipophilic agents constrained by dissolution rate. SNEDDS are extremely efficacious in improving the oral bioavailability of lipophilic products and is quite promising for managing drugs unapt for oral delivery. Additionally, it's noteworthy that SNEDDS can be formulated into various solid dosage forms suitable for both oral and parenteral administration. This overview incorporates the advancements of SNEDDS' the mechanism involved in its spontaneous formation, its subcategories, composition, approaches employed for formulation, characterization, merits and limitations, and future potential. The review also lays stress on the progress in solid self-emulsifying delivery mechanisms and dosage forms.
