Emulgel: A Revolution in Topical Drug Delivery

Emulgels represent the next big step in topical drug delivery by combining the benefits of emulsions and gels with a view to enhancing the therapeutic efficacy of hydrophobic drugs. This review discusses composition, mechanism, preparation, evaluation, and therapeutic applications of emulgels. In the usage of emulgels, improvement takes place in drug solubility, stability, and skin penetration, thus addressing the shortcomings of conventional topical formulations. This paper discusses the science of emulgels and the dual control release system, involving both immediate and sustained drug release, it runs through the methodology of preparing emulgels by formulating the emulsion and gel phase separately and then finally forming the mixture with all lipid phases. The paper further discusses sophisticated formulation techniques, including high-energy emulsification and incorporation of nanoparticles. Standard evaluation methods for emulgels are outlined, covering the physical appearance, rheological properties, pH measurement, stability studies, and in vitro drug release testing. The therapeutic potentials for emulgels are explored within its myriad applications, which are severely aimed at dermatology and pain relief. It identifies stability, formulation complexity, and several more critical areas, from which the focus to avert problems in these areas can be taken. The authors discuss potential future research developments leading to personalized medicine, the collapse of nanotechnology, and expanded progressed therapeutic applications. To conclude, although the emulgels secured much apprehension as to topical drug delivery, lots of things are yet to be done in the areas for further research in order to overcome various limitations that flummox them from wide use in clinics.
