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. Various approaches have been used to improve the efficacy of transdermal route such as vesicular system, 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 they are best suited for the transdermal delivery of higher molecular weight compounds. Due to the deformable nature of transfersomes, they penetrate into deeper layers of skin, retain their original structure after penetration and finally enter into the systemic circulation. This review focuses mainly on the 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.

More about this publication?
  • Current Drug Targets aims to cover the latest and most outstanding developments on the medicinal chemistry and pharmacology of molecular drug targets e.g. disease specific proteins, receptors, enzymes, genes. Each issue of the journal will be devoted to a single timely topic, with series of in-depth reviews, written by leaders in the field, covering a range of current topics on drug targets. These issues will be organized and led by a guest editor who is a recognized expert in the overall topic. As the discovery, identification, characterisation and validation of novel human drug targets for drug discovery continues to grow; this journal will be essential reading for all pharmaceutical scientists involved in drug discovery and development.
