Transferosomes: A Vesicular Tool for Transdermal Drug Delivery

Innovative lipid-based vesicles called transferosomes are designed to improve the delivery of transdermal medications. These ultra-deformable vesicles, comprised of phospholipids and edge activators, can successfully pass through the skin's stratum corneum and overcome conventional obstacles, resulting in better absorption of medications. Transferosomes have potential uses in treating several illnesses, such as cancer, and various skin ailments, and for vaccine delivery. They are also used to improve the bioavailability of poorly absorbed oral medications. Despite wide applications, the transferosomes formulation approach has limitations in scalability, stability, regulatory approval, and patient compliance, which must be addressed in ongoing and future research to maximize their therapeutic applications and establish transferosomes as a breakthrough in non-invasive drug delivery technology. This review covers the technical aspects involving the composition, structure, mechanisms of action, and formulation approach of transferosomes with comparison to other approaches, which will surely be beneficial for exploring novel targeted approaches involving liposomes, niosomes, ethosomes, and pharmacosomes.
