Congratulations! You have completed Module 5 that taught you about skin properties
Transdermal Delivery Systems.
Remember these key points:
- The four purposes of the skin are communication, metabolism, protection,
and sensation.
- The three layers of the skin include the epidermis, dermis, and subcutaneous
tissue.
- Transdermal delivery systems work through the diffusion process, but they
must pass through the skin barrier to be effective.
- There are two delivery methods for transdermal delivery systems: reservoir
and matrix.
- Ortho EvraTM, a contraceptive patch worn
for seven days over a three-week period, uses the matrix delivery system.
