Emulgel is a novel topical drug delivery system that combines the advantages of gels and emulsions to enhance drug penetration, stability, and patient compliance. Conventional topical formulations of drugs, such as creams, gels, and ointments, often possess problems with drug solubility, permeability, and retention. Emulgel is effective by utilizing an emulsion in a gel base, which overcomes the disadvantages of a gel base, provides dual-controlled release at the same time, and improves spreadability and bioavailability. Due to its unique structure, which allows for the effective entrapment of either hydrophilic or lipophilic drugs, emulgel is well-suited for diverse pharmaceutical and cosmetic applications. In addition, the gel base provides a non-greasy consistency that ensures prolonged drug contact with the skin and increased patient tolerability. Surfactants and penetration enhancers added to emulgel formulations likewise promote transdermal drug uptake and increase therapeutic activity. Recent studies highlight their innovation as a superior alternative to traditional systems, supporting applications in dermatology, pain treatment, and wound healing. Moreover, emulgel is an alternative candidate in the pharmaceutical industry due to the ease of large-scale production and formulation flexibility. This review outlines the formulation techniques, role of excipients, therapeutic advantages, and recent advancements in emulgel technology, with an emphasis on improving the drug delivery of topical pharmaceutical medicaments. By organizing recent findings and emerging trends, the article aims to provide insight into their potential as a novel and superior modality for enhanced transdermal delivery, effectively overcoming the limitations of traditional topical dosage forms.
