Primary Outcome Measures

Name	Time	Method
Change in Percent adhesion	0, 3, 6, 8, 10, and 12 hours	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.

Secondary Outcome Measures

Name	Time	Method
Adverse events	12 hours	The number of adverse events observed in each treatment will be used to assess the safety and tolerability of the four interventions
