Abstract
Advanced drug delivery system has now gained preference over the conventional drug
delivery system. One such research is nanoemulsion which is famous among the researchers
because of ease of formation, stability, clarity, increased absorption rate leading
to increasing in bioavailability and potential to form a formulation with both lipophilic
as well as the hydrophilic drug. Long lasting stability (up to years) and ability
to encapsulate both lipophilic and hydrophilic drug has given this colloidal system
a valuable position in drug delivery. This article contains information on components
required for its fabrication, preparation methods and evaluation parameters along
with its application in drug delivery and future aspects of this advanced drug delivery
system.
Key words
