APIs (3.1.225): The getApproximateMatch function returns the source and, if permissible, the name of each atom, in addition to the RxCUI and RxAUI as before. Names of atoms from RxNorm's restricted sources (SRL>0) are returned only if the request includes a UTS API key in good standing. RxNav's "default paths" table, which drives API functions including getRelatedByType, has been adjusted to improve bidirectional consistency of relations involving some branded term types. Details

APIs (3.1.246): The RxNorm API's getRxcuiHistoryStatus function has been enhanced to reflect ongoing curation of the RxNorm vocabulary, support historical clinical analytics, and improve consistency of reports about concepts that were active at different times. Details RxNav's "default paths" table and API function getRelatedByType have been adjusted to use RxNorm's direct link from SCDF and SBDF to DF. With this change, RxNav shows a DF related to every SBDF or SCDF, even if there are no related active drugs.

Upcoming changes: On or about August 7, 2023, RxNav concept properties concerning the ingredients or strength of individual drug components of SBD/SCD concepts will be removed. The corresponding information is reported more clearly by getRxcuiHistoryStatus. The concept properties that will be removed are flagged at getAllProperties. On or about November 6, 2023, MeSH codes and names will no longer be available or searchable in RxNav, and RxClass will no longer show MESHPA classes. These changes are in keeping with RxNorm, whose last release including MeSH will be the October 2023 release.

RxClass (3.1.110), APIs (3.1.254): Added class source ATCPROD, associating RxNorm drug products with ATC (level 1-4) drug classes. ATCPROD classes are shown in RxClass and RxNav. Details RxNav (2.9.119): Collected RxNorm drug-concept information on an "RxCUI" tab, consolidating the former Properties and Status tabs. The narrowest ("mobile") view has been simplified by the removal of Classes and Interactions.
