A review article on transethosomes: revolutionizing drug delivery through transdermal patches.

Abstract

Transethosomes, advanced nanovesicular carriers, have emerged as a revolutionary drug delivery system, particularly for transdermal patches. Combining the structural flexibility of ethosomes and the penetration-enhancing properties of surfactants, transethosomes offer remarkable advantages in overcoming the skin barrier to deliver a broad range of therapeutic agents. These vesicles enhance drug permeation, improve bioavailability, and enable controlled and sustained release, making them a promising alternative to conventional drug delivery methods. This review explores the unique composition, mechanisms of action, and penetration pathways of transethosomes while highlighting their application in various therapeutic areas, including pain management, dermatology, and hormone replacement therapies. Additionally, the article discusses the potential for transethosomes to target specific skin layers or cells, improving drug localization and minimizing systemic side effects. Current challenges, such as formulation stability, variability in skin types, and regulatory hurdles, are critically analyzed, alongside underexplored areas like large biomolecule delivery and multi-drug systems. Emerging trends, including personalized medicine, combination therapies, and stimuli-responsive formulations, are also reviewed, emphasizing the future potential of transethosomes in drug delivery innovation. By addressing these aspects, this article provides comprehensive insights into the transformative role of transethosomes in revolutionizing transdermal drug delivery systems.
