Imaging and quantifying drug delivery in skin - Part 1: Autoradiography and mass spectrometry imaging. Adv Drug Deliv Rev. 2019 Nov 25;: Authors: Grégoire S, Luengo GS, Hallegot P, Pena AM, Chen X, Bornschlögl T, Chan KF, Pence I, Obeidy P, Feizpour A, Jeong S, Evans CL Abstract In this two parts review we present an up-do-date description of different imaging methods available to map the localization of drugs on skin as a complement of established ex-vivo absorption studies. This first part deals with invasive methods and are grouped in two classes according to their underlying principles: i) methods using radioactivity such as autoradiography and ii) mass spectrometry methods such as MALDI and SIMS. For each method, a description of the principle is given along with example applications of imaging and quantifying drug delivery in human skin. Thanks to these techniques a better assessment of the fate of drugs is obtained, its localization on a particular skin structure, its potential accumulation, etc. A critical comparison in terms of capabilities, sensibility and practical applicability is included that will help the reader to select the most appropriate technique depending on the particular problem to be solved.
