Microemulsion:A Current Review

Microemulsions, which has considerable potential to act as a drug delivery system is becoming the area of interest for the pharmaceutical scientist. In pharmaceutical fields, the interest in microemulsion is increasing and, thus, they are applied to various administered routes. Being thermodynamically stable, these microemulsions are composed of an aqueous and an oil phase along with the surfactants. An understanding of the physicochemical and biopharmaceutical characteristics of microemulsion will provide guidance for the designing of their formulation. Besides the understanding of the formation and its characterization this article gives provides the knowledge of construction of the phase diagram of the microemulsion. This article also emphasis the recent developments and future discussions. Developments for poorly soluble drugs of microemulsion are also included in this review.
