RxNorm Adds USP Compendial Nomenclature Data Source

RxNorm Adds USP Compendial Nomenclature Data Source. NLM Tech Bull. 2018 Sep-Oct;(424):b5.

2018 September 06 [posted]

The National Library of Medicine (NLM) is pleased to announce the addition of United States Pharmacopeia (USP) Compendial Nomenclature as a new data source in RxNorm.

The addition of USP data to RxNorm helps support naming accuracy for drug substances in electronic environments. Integrating USP Compendial Nomenclature into RxNorm will help reduce nomenclature errors, particularly for substances with different salt forms (e.g. diclofenac potassium and diclofenac sodium). USP content will be integrated into RxNorm using a phased approach, beginning with substances, capsules, and tablets for the September release. USP Compendial Nomenclature is maintained and developed by the US Pharmacopeial Convention.
