Owing to recent developments in tritium chemistry and analysis, high‐quality tritium‐labelled drugs can now be prepared simply, cheaply and in timescales commensurate with those needed for rapid drug discovery in adsorption, distribution, metabolism and excretion (ADME) projects. Such 3 H‐labelled drugs are enabling high‐quality decision‐making at key points in the drug discovery process, thus ensuring more effective research projects, a key issue in commercial success. In addition, tritium‐labelled compounds continue to play a significant role in ADME studies later in the pharmaceutical development process. This is especially so for highly potent and hence low‐dose agents, for drugs with complex structures and for those compounds that undergo molecular fragmentation as a result of metabolism.
