Mapping concomitant medications to a standardized drug dictionary (e.g., WHODrug) to normalize analysis by ingredient and drug class.

Example

Verbatim 'Tylenol' is mapped to the ingredient acetaminophen and relevant ATC classification.

Common mistakes

Not capturing enough verbatim detail (dose form/strength) to code accurately, causing high coding queries.
