Description

Get the relationship names in the RxNorm data set.

Scope

Active: concepts in the current RxNorm data set that have an atom with SAB=RXNORM and SUPPRESS=N

Parameters

Note that HTTP requires that query parameters be "URL encoded". For full information on URL encoding, please refer to IETF RFC 3986, "Uniform Resource Identifier".

Output structure

Results are available as either XML or JSON.

• The XML result has the root element rxnormdata. It is described in the XML Schema for the Prescribable RxNorm API; the relevant element structure is summarized below. Elements that would be empty might be left out.

• The JSON result is an object {...}, analogous to the content of the XML rxnormdata. Fields that might occur multiple times in the XML are expressed as an array. Fields that would be empty might be null or left out. Numbers are expressed as strings.

Both XML and JSON results follow the same outline:

rxnormdata

Root element in XML, or anonymous object in JSON

relationTypeList

relationType (array)

Relationship name

Example: Relationship types

XML: https://rxnav.nlm.nih.gov/REST/Prescribe/relatypes
