Review Article of Nanoemulsion Drug Delivery System

Abstract

Emulsions are liquid-liquid dispersions in which tiny droplets of one liquid phase are distributed throughout the other liquid phase. Because of their appealing qualitiessuch as their small size, high surface area per unit volume, improved dispersion of active hydrophobic components, and enhanced absorption nanoemulsionsemulsions with sizes ranging from tens to hundreds of nanometers have a wide range of potential uses in pharmaceutics, foods, and cosmetics. Beginning with an introduction to emulsion kinds, preparation, and stability, the article gives a general review of nanoemulsions for drug delivery. Surfactants are essential for creating and maintaining nanoemulsions. Small molecule, particle, phospholipid, peptide, and protein surfactants are among the several forms of surfactants that are enumerated. The uses of nanoemulsions in drug delivery as nanomedicine are then discussed.
