Assessing the potential of skin electroporation for the delivery of protein- and gene-based drugs

Although transdermal drug delivery has many potential advantages, the permeability of skin to macromolecules is extremely low. However, the application of short, high-voltage pulses to electroporate skin has recently been shown to make it reversibly permeable. A number of studies have demonstrated that electroporation-mediated transdermal delivery of peptides, polysaccharides, oligonucleotides and genes may be possible at clinically relevant rates, leading to the current commercial development of electroporation techniques.
