  • Discussion of challenges and future potential for transdermal administration.

Main Results:

  • Incremental progress in passive transdermal systems addressing skin barrier and irritation.
  • Development of non-passive systems enabling delivery of larger molecules like proteins.
  • Identification of industry acceptance as a critical factor for transdermal delivery expansion.

Conclusions:

  • Transdermal drug delivery is progressing with new technologies for complex molecules.
  • Wider adoption by the pharmaceutical industry is essential for realizing the full potential of transdermal drug delivery.
  • The future of transdermal delivery hinges on overcoming regulatory and market acceptance hurdles.
