There are currently about 7000 standard concepts in RxNorm Extension vocabulary that specify “homeopathic potencies” in drug_strength table. They were built from source vocabularies that don’t distinguish between proper drugs and homeopathy, giving explicit ‘dosage’ for both.
This causes problems as per RxNorm and RxNorm Extension logic all primitive standard concepts like Branded/Clinical Drug Forms are built from such concepts. This could cause drug concepts like 41117395 “Epinephrine 30 C Oral Tablet Box of 1” as well as their mapping targets to be included in concept set for epinephrine-containing drugs, despite not containing a single molecule of the hormone.
We could cut all homeopathy from drug hierarchy and reclassify it as standard Devices.
Is there any non-obvious use case for when homeopathy concepts are useful? Should we keep them?
