RxNorm is a standardized nomenclature for clinical drugs. RxNorm is produced by the National Library of Medicine (NLM). In this
context, a clinical drug is a pharmaceutical product given to (or taken by) a patient with a therapeutic or diagnostic intend. The
name of the drug in RxNorm combines its ingredients, dosage strength, and form.
The RxNorm Related Concepts file contains a subset of the data distributed by NLM in the RXNREL.RRF file. This file follows the
general format of the MRREL.RRF file of the Metathesaurus in NLM's Unified Medical Language System (UMLS). Some of the
Metathesaurus fields are not provided by RxNorm and are marked as "(no value provided)". There is one row in this table for each
relationship between concepts or atoms known to RxNorm. In addition, explicit SY RELs are provided which give the UMLS
Metathesaurus CUI and AUI as the RXCUI2 and RXAUI2 fields.
Note that for asymmetrical relationships there is one row for each direction of the relationship. Note also the direction of REL -
the relationship which the SECOND concept or atom (with Concept Unique Identifier RXCUI2 and Atom Unique Identifier (RXAUI2) HAS TO
the FIRST concept or atom (with Concept Unique RXCUI1 and Atom Unique Identifier RXAUI1).
