We have been hearing a lot about RxNorm and the fact that it is the recommended national standard for medication vocabulary for clinical drugs and drug delivery devices produced by the National Library of Medicine (NLM).
A standardized nomenclature that relates itself to terms from other sources can serve as a means for determining when names from different source vocabularies are synonymous (at an appropriate level of abstraction). The goal of RxNorm is to allow various systems using different drug nomenclatures to share data efficiently at the appropriate level of abstraction.
What is the purpose of RxNorm? Because every drug information system that is commercially available today follows somewhat different naming conventions, a standardized nomenclature is needed for the smooth exchange of information, not only between organizations, but even within the same organization. For example, a hospital may use one system for ordering and another for inventory management. Still another system might be used to record dose adjustments or to check drug interactions. Several cooperating hospitals might have different systems, and find their data incomparable.

To support our customers who are developing healthcare IT applications that require medication vocabulary interoperability — such as those in EMR systems for e-prescribing, Lexi-Comp offers the RxNorm mappings within our Lexi-Data product. Interoperability is vital for healthcare IT systems using different drug databases to successfully communicate drug information across different platforms.
Lexi-Data is the foundation of Lexi-Comp's clinical decision support architecture. This product provides patient specific alerts and referential content to support sound treatment decisions in areas such as drug interaction checking (drug-drug and drug-food), drug allergy checking, therapeutic duplication checking, dose range checking (adult and pediatric) and more.
