Abstract

The skin, commonly considered to be the largest organ of the human body, has been used as a drug delivery route for numerous dermal and transdermal drugs. Being a structural barrier protecting the underlying tissues, the skin poses many challenges to be used as an amenable passage for drugs to permeate. In this chapter, we would describe the current advantages and disadvantages of transdermal drug delivery, making comparisons with different drug delivery routes, elucidate the mechanisms of passive and active transdermal drug delivery and deliberating different formulations which can be delivered via the transdermal route. We would investigate the current status and the development of microneedles, a strategy invented to transiently breach the skin’s stratum corneum to deliver drugs through the skin. We would also investigate the different types of microneedles, provide insights into the microneedles used in clinical trials and diffusion cell systems used to assess the efficacy of microneedles in their capacity to deliver drugs through the skin.
