Description

Get the brands that contain all the ingredients specified (as RXCUIs) by the ingredientids parameter.

Scope

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

Parameters

All query parameters are case-insensitive.

Note that HTTP requires that query parameters be "URL encoded". For instance, a "space-separated list" will, in practice, usually appear to use either a plus sign (+) or %20 as the separator. 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:
