I am a pharmacist doing drug term mapping in Korea.
I found an error in using RxNorm and RxNorm Extension vocabulary and posted it on this forum.
concept code=OMOP4670717 (concept class=Clinical Drug, concept name=Cimetidine 50 MG Oral Tablet)
concept code=309300 (concept class=clinical drug, concept name=cimetidine 4.8 MG/ML Injectable Solution)
The correct name for these drugs is cimetropium (bromide), which is listed as cimetidine.
Since “cimetropium” and “cimetidine” are different drugs, please review and correct them.
