RxNav

Medication tablets and RxNorm browser.
Project information
Researchers: 

Released in September 2004, RxNav was developed as an interface to the RxNorm database and was primarily designed for displaying relations among drug entities. In addition to the browser, SOAP-based and RESTful application programming interfaces (APIs) were created, enabling users to integrate RxNorm in their applications. Examples of use include mapping drug names to RxNorm, finding the ingredient(s) corresponding to a brand name, and obtaining the list of NDCs for a given drug.

LHNCBC has recently released SOAP and RESTful APIs for two additional drug information sources integrated with RxNav: RxTerms, an interface terminology for prescription writing or medication history recording; and NDF-RT, a resource that links drugs to their pharmacologic classes and properties, including indications, contra-indications and drug-drug interactions.
