Design and Analysis of an Emulgel Including Microcapsules of Etoricoxib

Abstract

Microcapsules have gained significant attention in pharmaceutical and cosmetic applications due to their ability to protect and control the release of active ingredients. Emulgel, a hybrid formulation combining the properties of emulsions and gels, serve as an ideal carrier for delivering active agents through topical or transdermal routes. This study explores the incorporation of microcapsules containing active compounds into an emulgel matrix, focusing on the formulation's stability, rheological behaviour, and release kinetics. The microcapsules were prepared using [technique, e.g., solvent evaporation], encapsulating [specific active ingredient], and characterized by size, morphology, and encapsulation efficiency. The developed emulgel system was evaluated for physical stability, drug release profile, and skin permeation efficiency. The results demonstrated that microcapsule incorporation enhanced the sustained release of the active ingredient while maintaining the structural integrity of the emulgel. The rheological analysis revealed that the microcapsule-loaded emulgel exhibited non-Newtonian behaviour, which is beneficial for topical application. Furthermore, the optimized formulation showed favourable permeation characteristics, suggesting its potential for improving the bioavailability of poorly soluble drugs. This research highlights the advantages of combining microcapsules with emulgel systems, offering promising opportunities for advanced drug delivery in topical and transdermal therapies.
