RxNorm API

The RxNorm API (http://mor.nlm.nih.gov/download/rxnav/RxNormAPIs.html#l ) is a web service for accessing the current RxNorm data set. RxNorm provides normalized names for clinical drugs and links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, Gold Standard Alchemy, and Multum. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.
