PurposeHeat therapy is widely used for pain relief and may unintentionally be used in conjunction with pain relieving topical formulations. The purpose of this study was to evaluate the influence of heat on the permeation of diclofenac through porcine and human skin, comparing four marketed products.MethodsIn vitropermeation tests (IVPT) were performed on porcine skin from a single miniature pig and human skin from three donors. Skin temperature was maintained at either 32 ± 1°C or 42 ± 1°C to mimic normal and elevated skin temperature conditions, respectively.ResultsIVPT studies on porcine and human skin were able to demonstrate heat-induced enhancement in flux and cumulative amount of drug permeated from the four diclofenac products. The pivotal data showed the most significant heat-induced enhancement for the solution, followed by the patch and two gels in decreasing order of significance based onpvalues. Diclofenac solution showed the highest flux and cumulative amount permeated at both baseline and elevated skin temperature compared to the patch and gels.ConclusionsThe studies demonstrated that exposure to heat can alter drug permeation from topical formulations, but the increased levels are not expected to lead to systemic concentrations that are of concern. Formulation design and excipients can influence drug permeation at elevated skin temperature.
