The nomenclature for today's commercial drug information systems follows a variety of naming conventions. Within any given hospital, there might be one system for ordering, another for inventory management, and yet another for recording dose adjustments. A smooth electronic exchange of the information in these systems is necessary for assuring patient safety. In this article, the authors discuss RxNorm, a standardized nomenclature for clinical drugs that is one of a suite of standards designated for use in the US federal government systems for the electronic exchange of clinical health information. Developed by the National Library of Medicine (NLM), RxNorm is based on a model developed at the NLM in consultation with the Health Level 7 vocabulary technical committee and with the Veterans Administration. It organizes data by concept and can recognize strings of characters from disparate sources as the same thing. The article also outlines planned future enhancements to RxNorm and the various Java components built around its framework.
