Abstract

It is not very long back that creams and gels were the mainstay in the topical drug delivery segment. But with the limitations of gels and creams calling for medication in the topical dosage form led to breakthrough development of emulgel as a topical dosage form. Emulgel had the obvious advantage of delivering hydrophobic drugs that gave them an extra edge over creams or gels which mainly could deliver only hydrophilic drugs. This review provides information regarding rationale and advantages of emulgels over other topically administered semisolids. Various gelling agents that could be incorporated in emulgels have been explored and discussed in this review. Other ideal drug candidates for emulgels have also been discussed. The possible oils and penetration enhancers that may be added have also been explained through this review. At the end few marketed formulations also have been mentioned like Voltaren. Further the review discusses the current reseach scenario and developments in field of emulgel preparation.
