The purpose

The purpose of this single-blinded study in healthy volunteers is to select a Low-Concentration Capsaicin Topical Liquid (LC-CTL) to serve as a control formulation in the further clinical development of Capsaicin Topical Liquid, NGX-1998 (10% w/w). The goal is to identify a low concentration formulation that will not reduce ENFD in healthy normal volunteers when compared to NGX-1998 (10% w/w) but would still produce some local capsaicin-related application site responses (e.g. erythema, heat sensation or pain) when applied.
