The aim of this work was to study the feasibility of using Positron Emission Tomography (PET) imaging as a new tool to detect transdermal penetration of topical drugs in human subjects. The compound used in the study is sodium 2-[(2,6-dichlorophenyl)amino]phenyl]acetate, better known as diclofenac sodium. This molecule belongs to the family of non-steroidal anti-inflammatory drugs and is considered one of the first choices among non-steroidal anti-inflammatory drugs for the treatment of inflammatory diseases; it is widely used and commercially present in a large number of pharmaceutical forms and formulations. 11C-labeled diclofenac has been synthesized and coformulated, as an internal indicator, with a proprietary preparation based on the use of a sprayer. The radiolabeled preparation was topically administered to healthy volunteers, and PET imaging was used to evaluate transdermal penetration. Results obtained have demonstrated the efficacy of PET and radiolabeled tracers for the evaluation of transdermal penetration of active pharmaceutical ingredients as topical formulations.
