Peptides and proteins are gaining increasing importance as therapeutic agents. Oral
delivery of these molecules is not feasible due to gastrointestinal degradation. Parenteral
delivery leads to poor patient compliance especially because the short half-life of peptides
necessitates repeated administration. Passive transdermal delivery is not feasible but active
transdermal delivery of peptides and proteins is a promising alternative route of
administration which can bypass gastrointestinal degradation and offer patient compliance …
