| Outline of Final Research Achievements |
In the transdermal drug delivery methods, the microneedle-mediated drug delivery system(DDS) has been developed to replace the hypodermic injection-mediated DDS, to provide painless self-administration of biological drug with patient friendly manner. Dissoluble microneedles are attracting much attentions as it has several advantages such as no needle-related risks. We have developed new fabrication method for biodegradable microneedles patches, which is different with the conventional fabrication ones, such as stepwise casting method. We anticipate that shadow mask assisted drawing lithography will be suitable to improve the fabrication throughput of dissoluble microneedle for new generation of drug delivery system.
On the other hands, we observed the permeability of several commercially-available microneedle patches for cosmetic purposes to human skin and investigated methods of evaluating permeability to the stratum corneum, and its’ degree of pain.
