ABSTRACT

The goal of an optimum drug delivery system is to maximise therapeutic benefit while reducing harm. Dosage forms have evolved over time and with advances in science and technology, from basic mixes and pills to extremely sophisticated systems known as innovative drug delivery systems. A nanoemulsion is a heterogeneous system made up of droplets of one immiscible liquid scattered throughout another liquid. Nanoemulsion droplets range in size from 20 to 500 nanometers. Because of small droplet sizes result in clear emulsions, the inclusion of an oil phase has no effect on the product's appearance. They have a lot of benefits, but they also have some drawbacks. High-energy and low-energy approaches are used to make nanoemulsions. Because of its improved drug solubilization capability, long shelf life, ease of preparation, and better drug bioavailability, this formulation has recently attracted a lot of attention for the administration of both hydrophilic and hydrophobic medicines as drug carriers. In this review types of nanoemulsion, method of preparation, evaluation and applications has been discussed.
