BTW: 1718849 “rucaparib camsylate” 1862578 is not a Standard Concept. it’s a so-called “Precise Ingredient”. The Ingredient that you will need to pull data is 1718850 “rucaparib” 1862579.
Thanks for the help, @Christian_Reich ! I wonder why our source gives the clinical drug form as the source name, but has the precise ingredient RxNorm code?!? Even more perplexing is why our OHDSI vocabulary/Concept table doesn’t have these two RxNorm codes.
I know. RxNorm does it. It gives the precise ingredient in the drug name, but links to the “imprecise” one. In reality it doesn’t matter. The main (“imprecise”) ingredient has a one-to-one, and rarely a one-to-many relationship to the precise ones.
Probably because you haven’t downloaded the vocabulary in ages, and now your version is old as dirt.
