SELECTED DRUG DELIVERY SYSTEMS BASED ON NANOEMULSION

M. Abd Elgadira and Aishah Adam*

Abstract

A nanoemulsion is recognized as an emulsion with a droplet size ranging from 20 to 200 nm. It can provide greater encapsulation efficiency for delivery. Nanoemulsions have unique characteristics such as extremely small size, biocompatibility, relative stability, ability to solubilize high quantities of hydrophobic compounds, ability to reduce toxicity of cytotoxic drugs and ability to protect drugs from hydrolysis and enzymatic degradation under physiological conditions. Nanoemulsions can be used in many drug delivery systems. This paper summarises utilization of selected nanoemulsions as anti– inflammatory, anti–cancer and anti–microbial in some drug delivery systems.

Keywords: nanoemulsion, drug delivery systems, anit–cancer, anit– inflammatory, anti–microbial, wound healing.
