  • 2. Brief History
    In 2001, National Library of Medicine (NLM) began experimenting in modeling drugs in the Unified Medical Language System.
    The area clinical drugs was seen important in the growing issue of patient safety.
    Aim was to develop improved interoperability of drug terminology.
    RxNorm is a standardized nomenclature for clinical drugs produced by the NLM.
    The RxNorm project approached clinical representation in a number of steps.
  • 3. Brief History
    The initial effort was to define Semantic Normal Form (SNF) to represent clinical drugs.
    SNF’s are canonical representations as defined by their strengths, active ingredients and orderable dosage form.
    There are two SNF’s created for every clinical drug:

  • 4. Purpose of Vocabulary
    The need of a standardized nomenclature for a smooth exchange of information.
    The goal is to allow various systems, using different terms to be able to share information effectively.
  • 5. RxNorm: Uses and applications
    RxNorm contains the names of prescriptions and many nonprescription formulations that exist in the US.
    Over the counter drugs will be added when reliable information about the medicine can be found.
