Abstract

Nanoemulsions are biphasic dosage form possessing the dispersion of two immiscible liquids one may be either oil in water (O/W) or either water in oil (W/O) droplets stabilized by amphiphilic surfactants. These are examples of the unstable heterogeneous biphasic dosage form system. These act as an important dosage form for water insoluble drugs. These are used to mask the taste and also act in the sustained release formulations. This review tries to focus on the current advanced methods including Micro emulsion, Multiple emulsion, and Nanoemulsion. In this modern era an advanced mode of drug delivery system has been introduced to overcome the major drawbacks associated with conventional drug delivery system. This review tries to focus on the new idea about the nanoemulsion system also the attention is focused on the basic idea about its formulation, method of preparation, characterization techniques, evaluation parameters, and various applications of nanoemulsion.
