A comprehensive review on applications, preparation & characterization of nanoemulsion

Abstract

With time, dosage forms have progressed, from essential tablets to advanced systems, which are now more focused on providing better ease of administration to the patients. One such advantageous novel drug delivery system is Nanoemulsion based drug delivery. The Nanoemulsion-based system is reasonably a new means of enhancing drug delivery; Nanoemulsions are sub-micron size particles roughly in the size range of 50-600 nm. The review focuses on conveying information by combining various articles and study reports to understand the work done in this field. This review paper aims to serve as a tool to understand the development of Nanoemulsion. The study comprehensively analyses the preparation methods, composition, characterization, and stability and their application in drug delivery via various routes. Lastly, the paper also describes the recent five formulations prepared for nanoemulsions and their applicability as discussed in the literature.
