A therapeutic agent delivery device can be applied onto a host in order to therapeutically administer a therapeutically active agent to the host, wherein the device incorporates a reflective optical film. Use of reflective optical films in patch devices allows a wide variety of visual elements to be incorporated into these devices without relying upon any colorants, dyes, inks, toners, or other materials. These visual effects include logos, high reflectivity, iridescence, graphics, printed information, surface microstructure, bar codes, color, designs, and/or the like. The present invention also improves the barrier qualities of patch drug devices, prolonging shelf life. This enhanced barrier protection is desirable for all patch therapeutic agent delivery devices, but is particularly beneficial for devices containing fluid reservoirs in which the therapeutically active agent(s) might be stored. |
