Brief Summary

This study is a single-center, open-label, single-dose trial performed in a randomized, four-way, change-over design in healthy volunteers. The primary purpose of this study is to evaluate the effect of moderate heat, occlusion, and moderate exercise on pharmacokinetics. The secondary purpose is to characterize the effect of special conditions on the bioavailability and to evaluate patch adhesion and safety of TK-254RX and a residual amount of the patch.
