The RxNorm browser RxNav and application programming interfaces (APIs) support the adoption and distribution of RxNorm, the NLM standard terminology for drugs. RxNav and companion APIs also extend the scope of RxNorm by linking RxNorm drugs to physician-friendly terms (RxTerms), and drug classes (RxClass). RxMix allows users to combine API functions to build applications. RxNav-in-a-Box provides users with a locally installable version of the APIs and applications.
