Abstract: Self-nano Emulsifying Drug Delivery Systems (SNEDDS) are novel formulations that can enhance
the solubility and bioavailability of poorly water-soluble drugs. SNEDDS are composed of lipids, surfactants,
co-solvents, and drugs and can spontaneously form nanoemulsions when mixed with water under mild agitation.
SNEDDS can be formulated as liquid or solid dosage forms and can improve drug absorption by increasing
the interfacial area, protecting the drug from degradation, and facilitating lymphatic transport. SNEDDS is
characterized by various parameters such as particle size, zeta potential, droplet morphology, emulsification efficiency,
drug solubility, and stability. SNEDDS offers several advantages over conventional dosage forms,
such as dose reduction, faster onset of action, reduced variability, versatility, and ease of formulation. However,
SNEDDS also face some limitations and challenges, such as drug precipitation, cost-effectiveness, compatibility
with capsule shells, and lack of predictive in vitro models. SNEDDS has a promising future in the field
of pharmaceuticals, especially for personalized medicine and targeted drug delivery.
