Summary
The purpose of this study is to evaluate potential changes in epidermal nerve fiber
immunostaining (ENFI) and sensory nerve function in healthy normal volunteers following
single applications of three different investigational topical Capsaicin Dermal Liquids (10%
w/v trans capsaicin), and a comparable control (propylene glycol). In addition, the pain and
tolerability of the application of each formulation will also be assessed. Data from this
clinical study may be used to select a formulation for further clinical evaluation.
