Percutaneous penetration enhancement in transdermal drug delivery

Main Article Content

The transdermal route has numerous advantages over the more traditional drug delivery routes. These include high bioavailability, absence of first pass hepatic metabolism, steady drug plasma concentrations, and the fact that
therapy is non-invasive. The main obstacle to permeating drug molecules is the outermost layer of the skin, the stratum corneum. Consequently, research into enhancing transdermal drug delivery (TDD) by overcoming this layer, is an area
of prime interest. This review article is written to provide a coverage commentary of the recent advancements in TDD
enhancement techniques.
