2Hydration Subsumption (incl. less granular Clinical Drug)50 min
@Canada
@All
  • Proposal from Canada
  • Group discussion on options


Meeting Notes

Discussion on options proposed for managing hydration subsumption:

  1. Less granular Clinical Drug - beneficial for other reasons, but likely a more complex discussion and piece of work
  2. CGI - complex in terms of modelling, and a workaround that may be replaced by a less granular clinical drug
  3. Solvate modification to substances - presents good option to manage the current challenge. Areas such as concept definitions, role chains, PAIs that are also BoSS, and challenging substances need to be worked through.

Canada will share list of c.200 known hydrated substances - to be used by group to explore approach to option 3 and help identify possible challenging cases. Examples highlighted included choral hydrate, caffeine injection, pramipexole, tacrolimus.
