RxNav Overview

RxNav Views

Overview

RxNav has a number of views (tabs) which display related information of the selected concept.

RxNav views (tabs) for displaying other related information

The Graph View is the default view and displays the selected concept with its related RxNorm concepts.

The RxCUI View contains the the status, metadata, and properties of the selected RxNorm concept.

The NDC View displays the National Drug Code information for the concept.

The RxTerms View displays the RxTerms vocabulary information related to the concept.

The Class View displays drug class hierarchies from several drug vocabularies.

Graph View (Graph Tab)

The Graph View is the default tab when RxNav is started. When the user enters RxNav, the options for the graph are displayed on the left, and the graph components to the right of the options. The default graph is the classic graph, which contains ten tables containing the RxNorm term types.

After a search is done, the RxNorm graph is populated with the concept found plus the related concepts.

The concept found from the search string is highlighted. By clicking on a concept in one of the tables, that concept string becomes the search term and all of its related components will then be displayed.

To populate the display, RxNav uses a set of default paths to traverse from the starting concept term type to find related concepts of the different term types. The path table shows the default paths used for each starting term type.

Graph Types
RxNav provides a classic graph view, a simple graph view and a table view, selectable under the Views label in the options:

RxNav graph views

The simple view provides two tables, one containing the ingredients and related products, the other for brand names and related branded products. The figure below contains the simple view for the ingredient ezetimibe.

RxNav simple view

The table view provides the same information as the classic view, but in a single table. The figure below contains the table view for the brand Celexa.

Graph Filters
RxNav provides filters for the classic and simple graphs:

Graph filters

The selection of a filter implies that the graph should contain only those entries. For example, selecting Human means only those drugs containing the H or HV icon are selected for the graph. Selecting Human and Vet will result in only those drugs displaying the HV icon are selected. Similarly, selection of the prescribable filter (Rx icon) will eliminate non-prescribable concepts from the graph.

Group or Form Display
For the classic view, the user has the option of selecting either Group Term Types (default) or Form Term Types.

Group or Form TTYs

Links to other drug information

RxNav links for displaying other related information

Drug Label Link
This link provides the drug label information from DailyMed .

MedlinePlus Link
The MedlinePlus link allows users to view MedlinePlus drug information using the MedlinePlus Connect API. When the MedlinePlus link is selected, the MedlinePlus results web page is displayed.

Other Graph Symbols
The Legend provides other symbols which occur in the RxNorm graph.

RxNav Legend

MIN icon – identifies the concept as a multiple ingredient term type (MIN)
Pack icon – identifies the concept as a Pack term type (GPCK or BPCK)
Multi icon – identifies a concept related to a multiple-ingredient (MIN) concept

Download Button
The download button copies the information in the graph to a file with comma separated fields.

Default Paths

The default path table below shows the paths through the term types that are taken by RxNav to display the related concepts. (Note: these are also the paths used by the RxNorm API in the functions getAllRelatedInfo and getRelatedByType.)

The first and third columns indicate the starting term type associated with the selected identifier and the ending term type.
The second and fourth columns are the list of term types in order (the path) to get the related concepts of the ending term type from the starting term type.

Default Paths Table Notes

[1] This route takes a detour from a more direct route to find only clinically-relevant relations.

[2] This route takes a detour to ensure clinically-relevant results. A TTY visited more than once must be satisfied by the same RxCUI.



The RxCUI View (RxCUI Tab)

The tab labeled "RxCUI" allows the user to view the status, ingredients, features, and properties of the selected concept.

Possible statuses are:

  • Active - the concept is in the current RxNorm data set and has a non-suppressed term (SUPPRESS="N" in RXNCONSO) from the RxNorm vocabulary.
  • Obsolete - the concept is designated as obsolete (SUPRRESS="O" in RXNCONSO) in the current data set.
  • Quantified - the concept has been designated as an unquantified, non-prescribable drug (SUPPRESS="E" in RXNCONSO) in the current data set.
  • Non Current - the concept satisfies one of the following conditions:
    1. The concept exists in the current data set but has no RxNorm vocabulary terms.
    2. The concept existed in previous monthly versions but has been removed and is not remapped to any Active concepts.
  • Unknown - the RxCUI has never been present in an RxNorm monthly release
The properties include the RxNorm names, codes, attributes, and the vocabulary sources of other synonyms. A sample view is shown below.

RxNorm properties view for RxCUI=208848

The NDC View (NDC Tab)

The tab labeled "NDC" allows the user to view the National Drug Codes along with its properties for a clinical drug, clinical pack, branded drug, or branded pack. The tab will be enabled when a clinical drug, clinical pack, branded drug or branded pack concept is selected (by single-clicking on the concept). To view the NDC information for that concept, simply select the NDC tab. The default table is the current NDC. A sample table is shown below.

NDC graph example

NDC properties come from RxNorm, DailyMed (SAB=MTHSPL) in the RxNorm data set or from the FDA. The following table lists the source of the data for each column in the NDC table.

Column Title Source(s) of data
NDC9 FDA or DailyMed
NDC11 RxNorm
NDC10 FDA or DailyMed
SPL_SET_ID DailyMed
LABELER FDA or DailyMed
PACKAGING FDA or DailyMed
NDC9 PROPERTIES FDA or DailyMed

An example of NDC9 Properties

NDC properties example


A historical NDC table which contains both past and present NDC information is also available.

NDC graph example

The status column can contain the following values:
  • Indirect – indicates the NDC was associated to a different concept designated in the RxCui column.
  • Direct – indicates the NDC is/was associated with the current concept.
The start and end date columns indicate the period of time the NDC was considered active in RxNorm for the RxCui.

The RxTerms View (RxTerms Tab)

The RxTerms view in RxNav provides the RxTerms information for a clinical or branded drug. RxTerms is a drug interface terminology derived from RxNorm for prescription writing or medication history recording.

For more information on RxTerms, click here.

A sample view is shown below.

RxTerms View

Class View (Class View Tab)

The Class View contains drug class hierarchies from ATC, MED-RT, SNOMEDCT and VA. The Views menu on the left of the screen allows the selection of the class hierarchy to display. The ATC graph is selected as default.

Class Views

A sample graph with annotations is shown below. Note that there is a widget for zooming the graph as well as positioning. Also, clicking on a class node will link to RxClass for that drug class and display the drug members for that class.
