Abstract
Nanoemulsions have attracted great attention in pharmaceutical research and dosage form design. This is as a result of the various features peculiar to nanoemulsion such as ease of preparation, optical clarity, thermodynamic stability and increased surface area. Nanoemulsion having average droplet size in between 100-500 nm serves as a vehicle for the delivery of active pharmaceutical agents as well as other bioactives. They are designed to overcome the problems associated with conventional drug delivery system such as low bioavailability and noncompliance. The significance of designing and developing emulsion as a nanocarrier system aimed to control and/or improves required bioavailability levels of therapeutic agents. Nanoemulsions have been used as a carrier for various drug delivery system viz. topical, transdermal, gene delivery, intranasal, parenteral, pulmonary etc. Nanoemulsions as a carrier offer various advantages in drug delivery system. Aim of this article is to shed light on the use of the nanoemulsion in various types of drug delivery system and future prospective of nanoemulsion as a carrier.
