Amol Gund*, Shubham Wakde, Shrikant Divekar and Shilpa Chaudhary
Nanoemulsions are submicron sized emulsions which act as drug carriers for improving the delivery of therapeutic agents. In pharmaceutical observation, nanoemulsion is one of the chief dosage forms in delivering active ingredients to the objective area which has engrossed a great attention in recent years for its application in various fields. In the pharmaceutical field, nanoemulsions have been used as a drug delivery system through various systemic routes such as oral, topical and parenteral. Nanoemulsions are clear, thermodynamically stable, isotropic liquid mixtures of oil, water, surfactant and co-surfactant. These are oil-in-water (o/w) type of emulsions with the average droplet size ranging from 5nm to 100 nm. The focus of this review article is on nanoemulsion and its current applications in various pharmaceutical fields. the aim of this review is focused on nanoemulsion advantages, disadvantages, various methods of preparation, characterization techniques and the various applications.
Keywords: Nanoemulsion, drug delivery, flocculation, surfactant.
