Abstract

Nanoemulsion is a stable drug delivery system consisting of oil, water, and surfactant droplets with a size of 100nm. The emulsifier slows interfacial tension and stabilizes the nanoemulsion through electrostatic interaction and steric hindrance. This review mainly gives a brief image of naoemulsion Nanoemulsion can be used in place of conventional dosage form to overcome from its demerits. It contain oils, water and emulsifiers. It is used for to improving the solubility and bioavalability of the drug. The droplets size of nanoemulsion consist of 20-200nm range in the nanometric scale. It is prepared in multiple delivery forms such as gels, creams, aerosols and spray. It should be taken by various ways such as orally, intravenously, intraocularly, intrapulmonary, topically and intranasally. Nanoemulsions are formulations used in various body routes and can be manufactured at low prices in various dosage forms. They require less surfactant than microemulsions, making them suitable for cancer therapy, targeted drug delivery, cosmetics, and improves its solubility and the bioavailability is also increased. This review mainly provide knowledge about the types of nanoemulsion, itsadvantages, disadvantages, formulation of nanoemulsion and application.
