Comparison of the Bioavailability of Diclofenac in a Combination Product (Diclofenac 2% + Capsaicin 0.075% Topical Gel) With Two Diclofenac Only Products, Diclofenac Mono Gel 2% and Voltarol® 12 Hour Emulgel 2.32% Gel, in Healthy Volunteers

• Status: Completed
• Trial end date: 2017-06-29

Summary

The main objective of this study is to assess the relative systemic bioavailability of diclofenac in the presence and absence of capsaicin by comparing the systemic bioavailability of diclofenac from a combination product (Diclofenac 2% + Capsaicin 0.075% Topical Gel) with two diclofenac only products, Diclofenac Mono Gel 2% and Voltarol® 12 Hour Emulgel 2.32% Gel, following topical administration.

In order to examine potential racial differences in pharmacokinetics (PK), the study population will be stratified 50:50, Caucasian versus Black people. With respect to the main objective, additionally a supportive analysis will be performed to investigate the influence of race on the intra-individual bioavailability ratios.
