Emulgel: A revolution in topical drug delivery system

Abstract

Topical delivery of drugs is one of the ideal routes of administrating a wide range of drug candidates and emulgels are emerging as a novel formulation, which exhibited the characteristics of both the emulsions and gels. Emulgel demonstrated improved penetrability during several studies and it is able to deliver hydrophilic as well as hydrophobic drugs and hence overcome the limitations of traditionally available topical preparations. More stable and effective emulgels can be prepared by nanonizing and micronizing the globules of emulsions, which improves the stability and half-life of Emulgels. The commercial availability along with the presence of strong clinical pipeline of emulgels is indicating towards the acceptance of this formulation while several advantages associated with this approach is also suggesting towards its potential as ideal topical drug delivery system. This article enlisted in-depth information about the emulgels, its components and structure along with the general method of production, evaluation and future scenario of this approach. The article also involved information about the patents insight, commercially available products and previously used drugs for developing stable emulgels.
