Brief summary
The purpose of this study is to quantify the amount of diclofenac in rinse water after application of the test product (Voltaren® Schmerzgel forte; 2.32 percent \[%\]) containing 2.32% Diclofenac-N-Ethylethanamin either by hand or using an applicator and subsequent washing and/or wiping.
Detailed description
This will be an exploratory, open label, crossover study. Participants with healthy skin on the elbows and hands will be enrolled. The amount of diclofenac in rinse water after application of the test product (Voltaren® Schmerzgel forte; 2.32%) containing 2.32% Diclofenac-N-Ethylethanamin will be assessed after three different washing methods, with and without use of an applicator in a crossover design. There will be a wash-out period of at least 2 days in between each method. Approximately 40 participants will be enrolled in this study.

| Measure | Time frame | Description |
|---|---|---|
| Concentration of Voltaren® Schmerzgel Forte; 2.32% (Diclofenac) in Water (Milligrams Per Liter [mg/L]) After Washing | Day 1, Day 3 and Day 5 | The concentration of diclofenac in rinse water samples (mg/L) collected after application of the test product (Voltaren® Schmerzgel forte; 2.32%) was determined with High-performance liquid chromatography (HPLC). |
| Amount of Test Product Residues by Gravimetrical Measurements (in Gram) | Day 1, Day 3 and Day 5 | Test product (Voltaren® Schmerzgel forte; 2.32%) residue was collected using Method 3 (application of the test product using an applicator and subsequent wiping with a paper towel). The paper towels were weighed before and after wiping the test area. The amount of test product residue (gram) in paper towel= The weight of paper towel after product application minus weight of paper towel before product application. |
