RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, Gold Standard Drug Database, and Multum. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.

There is exactly one row in this dataset for each allowed value of selected data elements or attributes that have a finite number of abbreviations as allowed values. Examples of such data elements include TTY, ATN, TS, STT, REL, RELA.
