Transfersomes: self-optimizing carriers for bioactives.
The transdermal route of drug delivery has gained great interest of pharmaceutical research, as it circumvents number of problems associated with oral route of drug administration. The major barrier in transdermal delivery of drug is the skin intrinsic barrier, the stratum corneum, the outermost envelop of the skin that offers the principal hurdle for diffusion of hydrophilic ionizable bioactives. Recently, various strategies have been used to augment the transdermal delivery of bioactives. Mainly, they include iontophoresis, electrophoresis, sonophoresis, chemical permeation enhancers, microneedles, and vesicular system (liposomes, niosomes, elastic liposomes such as ethosomes and transfersomes). Among these strategies transferosomes appear promising. Transport of this vesicular system through skin and epithelial hurdle depends upon the flexibility of their membrane, which can be attained using appropriate ratio of surfactant. Transfersomes have shown immense potential in drug delivery across the skin. Recent success also demonstrates the potential of transfersome in vaccine, steroid, protein, and peptide delivery across the skin. It is also used for transporting genetic material and achieving transfection. This review highlights the various aspects of the transferosomes in the effective delivery of drug/bioactives across the skin.
