A review on nano emulsions in Novel Drug Delivery Systems (NDDS)

Abstract

Nanoemulsions are advanced drug delivery systems that consist of fine oil-in-water or water-in-oil dispersions stabilized by surfactants, with droplet sizes ranging from 20-200 nm. These nano-scaled emulsions have garnered substantial interest due to their potential to improve the solubility, stability, and bioavailability of poorly soluble drugs. This review aims to explore the formulation techniques, evaluation parameters, and advantages of nanoemulsions in novel drug delivery systems (NDDS). It delves into the methods used to prepare nanoemulsions, their physicochemical characterization, and their therapeutic applications, highlighting their significant impact on enhancing drug delivery.
