Drug concepts with lower granularity (medicine groups)

As for now, there’s no good option. The only work-around is certain procedural codes.

And we’re thinking of a couple of solutions. One of them is to allow to map to Classifications (ATC) and use them as event_concept_id.

But “biological therapy” won’t be useful anyway - too unspecific. Unless you have a good way to map to a drug group, it’s not helpful in studies.
