I thought compound information was used in this case (but the thread is from 2020, so maybe this information is outdated) @Christian_Reich How to calculate Quantity and effective_drug_dose? - General - OHDSI Forums you said: “If you don’t have a formulation, but you are recording a strength incorporated into a drug product (eg. Acetaminphen 500 mg) then use Clinical Drug Comp.” So when/for which cases is mapping at “compound” level used ?
