High‐Resolution LC‐MS Approach for In Vitro Metabolite Characterisation of Etonitazene in Camels for Enhanced Doping Control

This study highlights the effectiveness of advanced high-resolution LC-MS techniques in identifying and characterising the in vitro metabolites of etonitazene in camels. Due to its high potency and potential for misuse in camel racing, the identified metabolites serve as a foundation for effective doping control strategies. These findings contribute to improving regulatory frameworks designed to protect animal welfare and maintain the integrity of the sport.
