Status View Changes

The status tab view was changed to provide information from the /historystatus resource in the RxNorm API, which replaces the information previously provided by the now deprecated RxCUI History API. The status values have changed to either Active, Obsolete, Quantified, Remapped, NotCurrent or Not Found. In addition, a number of additional fields have been added.

Search by NDC

NDC status information is given when searching by NDC and the NDC is not currently active. In cases where the NDC is obsolete, RxNav will provide the concept information of the concept the NDC was last mapped to. NDCs that are out of scope for RxNorm, but are contained in other drug vocabularies are also handled by displaying the status information of the concept the NDC is associated with.

Class View changes

The class view tab contains a number of changes due to the transition from NDF-RT to MED-RT class data. Changes include:

• The Drug and DF views have been removed.
• EPC and VA views have been added.
• All views now use the RxClass API to get the nodes for the graphs
• DailyMed is the drug source used for the CHEM, MoA, PE and EPC views.
• MED-RT is the drug source used for the Disease and PK views.
• VANDF is the drug source used for the VA view.
• ATC and MESH views now will display graphs for drug products.

NDF-RT tab removed

The NDF-RT tab was removed as RxNav no longer accesses the NDF-RT API.

Status View Added

A tab labeled Status was added to provide status and historical information about the searched concept.

Search by GPI

RxNav users can now search by Generic Product Identifier (GPI) from the Master Drug Data Base.
Update: GPI codes are no longer searchable, because they are no longer included in RxNorm.

Table Downloads

Download buttons were added to the RxNorm Properties, NDC, RxTerms, NDF-RT, Pill Images and Interaction views so that users can download the information in the tables to their computers. A comma-separated-field text file is generated that can be imported into a spreadsheet.

Historical NDC Table

As part of the NDC tab, the historical NDC table was added which provides a history of the NDCs that have been part of the selected concept. Included in the table are NDC information of concepts that were remapped to the selected concept.

Table View Added

As part of the RxNorm Graph tab, the table view provides the same information as the classic view, but in a single table.
