A Detailed Review on Pharmaceutical Applications of Pickering Emulsion

Pickering emulsions, stabilized by solid particles rather than traditional surfactants, have gained significant attention in the pharmaceutical field for their unique physicochemical properties and enhanced stability. These emulsions offer a biocompatible and environmentally friendly platform suitable for various drug delivery applications, including oral, topical, and parenteral routes. Their ability to encapsulate both hydrophilic and hydrophobic drugs, protect sensitive bioactive, and provide controlled and targeted release makes them highly versatile. Recent advancements in the design of biopolymer- and nanoparticle-stabilized Pickering emulsions have further expanded their potential for improving drug solubility, bioavailability, and therapeutic efficacy. This review highlights the current developments, mechanisms, and future prospects of Pickering emulsions in pharmaceutical formulations, underscoring their promise as a next-generation drug delivery system.
