NANOEMULSION AS NOVAL DOSAGES FORM-A REVIEW

Dr. Amit Choudhary, Ashish Kumar*, Ajay Kumar and Dr. Abhishek Soni

ABSTRACT

Nanoemulsions are emulsions of the submicron size that are under study as drug carriers to enhance therapeutic agent delivery. These are the thermodynamically stable isotropic schemes in which two immiscible liquids are combined with appropriate surfactants and cosurfactants to form a single phase. Normally, nanoemulsion droplet sizes fall in the range of 20-200nm and display a small distribution of size. The focus of this review is to provide brief information on the formulation aspect, the preparation method, the characterization techniques, the evaluation parameters and the different application of nanoemulsions,several techniques are to be used for the preparation of nanoemulsions like microfluidization, high-pressure homogenization, low energy emulsification and solvent evaporation method and parameter that are to be used for its characterization like, viscosity determination, drug content, refractive index, pH, Transmission electron microscopy, droplet size analysis, zeta potential.

Keywords: Nanoemulsion, Self emulsification, Phase separation, High pressure homogenization.
