RxNorm Prescribable Names Added to DailyMed
DailyMed now includes an additional set of drug names from RxNorm, a drug terminology produced by NLM. You can now find RxNorm prescribable names (PSN), which are user-friendly and display-friendly synonyms for drugs, associated with many drug product labels. Prescribable names join the RxNorm normalized names and synonyms that were previously added to DailyMed drug product labels.
Additionally, you can now use a PSN filter with the '/rxcuis' DailyMed web service, which retrieves a list of all RxNorm codes (RXCUIs) for drug products. When applied, this filter limits your web service results to RxNorm prescribable names data.
