The Federal Medication (FedMed) interagency collaboration is organizing an agreed set of standard, comprehensive, freely and easily accessible Federal Medication Terminologies (FMT) to improve the exchange and public availability of medication information. FedMed is a joint effort of these Federal partner agencies:

• Food and Drug Administration (FDA)
• National Library of Medicine (NLM)
• Veterans Health Administration (VHA)
• National Cancer Institute (NCI)
• Agency for Healthcare Research and Quality (AHRQ)

The FedMed resources and related standards encompass medication and ingredient names, codes, routes of administration, dosage forms, units of presentation, mechanisms of action, physiologic effects, and structure. Participating agencies currently provide the following FMT components and related products:

• FDA's Unique Ingredient Identifier (UNII) codes for drug ingredients (see FDA Terminology Web page) and National Drug Codes (NDC) for prescription medications.
• NLM's RxNorm, for clinical drug names, and DailyMed, for viewing and downloading SPL-encoded drug labels.
• VHA's National Drug File Reference Terminology (NDF-RT) formulary. Three FMT-related SPL subsets of NDF-RT are described and accessible on the FDA Terminology Web page. Terminology for the full public release version of NDF-RT is available here in two versions: all data (zipped XML) and terms and codes (text).
• NCI Thesaurus (NCIt) for a range of supporting terminology sets and investigational agents. The FedMed-related SPL subsets of NCIt are described and accessible on the FDA Terminology Web page. NCIt as a whole is available via browser, file downloads, and application programming interfaces.

The initial FMT terminology set has been endorsed by U.S. Federal standards efforts including the National Committee on Vital and Health Statistics (NCVHS), Consolidated Health Informatics (CHI), and the Office of the National Coordinator for Health Information Technology (ONC) within the Department of Health and Human Services (HHS). An overview of the FMT goals, directions, and components is available in a jointly developed PowerPoint presentation. The FedMed partners are working with ONC to develop an Interagency Coordination Group that can support coordination, development, and use of the FMT standards.
