Evaluate the Ability of dOFM for BE Testing of Topically Applied Diclofenac Sodium Products in Healthy Subjects

Summary

This will be a single center, open label, exploratory research study to assess the dermal pharmacokinetic (PK) profile of three marketed diclofenac products in 26 healthy volunteers using dermal open flow microperfusion (dOFM). This clinical study aims to assess bioequivalence (BE) of three different diclofenac products.
