Administration of drugs through skin via transdermal route is a non-invasive approach and applicable for systemic delivery but it is not suitable for drugs having higher molecular weight. Many approaches have been used to improve the efficacy of transdermal route such as vesicular approach, iontophoresis, microneedles, use of permeation enhancers, etc. Among the several approaches, vesicular delivery is gaining importance in transdermal drug delivery. Transfersomes are one of the vesicular systems and best suited for transdermal delivery of higher molecular weight compounds. Due to the deformability nature of transfersomes, it penetrates into deeper layers of skin, after penetration retains its original structure and finally 9enters into the systemic circulation. This review focuses mainly on applications of transfersomes in the field of drug delivery i.e. delivery of analgesics, anti-cancers, proteins and peptides, immunomodulators, steroidal hormones and herbal drugs with increased penetration through skin. In addition, this review also deals with preparation methods available for preparing transfersomes, characterization, mechanism of penetration upon topical application and its kinetic aspects.
