Transdermal drug delivery is very challenging, and numerous strategies have been developed to overcome the skin barrier. This webinar will demonstrate the importance of the formulation on skin delivery, with a strong focus on solubilizers and permeation/penetration enhancers. We will describe the use of Franz cells in a diffusion testing system to assess the formulations with detailed information on the test methods.

Topics of discussion

  • Skin barrier and strategies for enhancing drug permeation
  • Role of excipients in solubilization, permeation, and skin penetration
  • Franz cells diffusion apparatus
  • Selecting appropriate membranes: synthetic, animal, or human
  • Developing reliable and robust protocols for IVRT or IVPT
  • Case studies with model drugs


  • Dr. Ashvin Patel, Director of Analytical Research & Business Development, Teledyne Hanson
  • Elise Dauphin-Chanard, Application Lab Manager, Gattefossé
  • Bruna Lousada, European Sales & Marketing Manager, Teledyne Hanson

The Teledyne Hanson Phoenix dry heat diffusion systems make diffusion‐cell testing faster, easier, and more economical. The Phoenix DB‐6 manual sampling system offers six‐cell manual sampling in a compact footprint with an advanced touch screen display. The Phoenix RDS Robotic Diffusion Station fully automates sampling, collection, and media replace with the ability to run up to 24 cells at once. Both systems rely on the new Phoenix™ dry heat diffusion cell, made from precision borosilicate glass, with mixer inserts engineered to produce instant homogenization of receptor media.
