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.
Keywords: Nanoemulsion, Micro Emulsion, Multiple Emulsion, Parenteral, Oral, Drug Delivery, High- pressure homogenization.
