APIs
Application Program Interfaces (APIs) are available to users to retrieve data from several drug information sources, including RxNorm, MED-RT and RxTerms. Currently these APIs are available:
- RxNorm API for retrieving data from the RxNorm data set
- Prescribable RxNorm API for retrieving data from the RxNorm Current Prescribable Content
- RxTerms API for retrieving data for the RxTerms data set
- RxClass API for retrieving drug classes and drug members from a number of different drug class types
- Drug Interaction API for accessing drug-drug interactions
The APIs are also available as part of RxNav-in-a-Box, which provides users with a locally-installable version of RxNav, RxClass, and the APIs.
The API resources can also be used interactively or in batch mode with RxMix.
