Brief Summary

The study is designed to evaluate and compare the clinical adhesion performance of the ZTlido (Lidocaine Topical System) 1.8% of Scilex Pharmaceuticals Inc. (Reference) versus Salonpas (Lidocaine Patch 4%), Aspercreme (Lidocaine Patch 4%) and IcyHot (Lidocaine 4% + Menthol 1% Patch), on the Mid to upper back while being worn for 12 hours in healthy adult human subjects.

Conditions

Healthy

Outcome Measures

Primary Outcomes (1)

• Change in Percent adhesion

  The adhesion performance (i.e., degree of lifting or detachment) is assessed by clinicians at each time point. The adhesion of Test Products 1, 2, and 3 (each over-the-counter external analgesic lidocaine-containing patch) are compared to the adhesion performance observed for the Reference Product.

  0, 3, 6, 8, 10, and 12 hours
