Electrically-assisted transdermal delivery also called iontophoresis is
the facilitated transport of compounds across the skin using an
electromotive force. The predominant mechanism for delivery is
iontophoresis, although electroosmosis and electroporation have also
been investigated. This Technique employed an innovative self-contained
battery that produces an electric current to carry drug molecules
non-invasively across the skin and to underlying tissue. Clinical
benefits, industry interest, regulatory precedence, and strong market
potential have made transdermal iontophoretic research the fast growth
area in drug delivery.
