D01: Find drug concept by concept ID

This is the lookup for obtaining drug concept details associated with a concept identifier. This query is intended as a tool for quick reference for the name, class, level and source vocabulary details associated with a concept identifier.
This query is equivalent to G01, but if the concept is not in the drug domain the query still returns the concept details with the Is_Drug_Concept_Flag field set to ‘No’.

Input:

 Concept ID  1545999  Yes Concept Identifier from RxNorm for ‘atorvastatin 20 MG Oral Tablet [Lipitor]’
 As of date  Sysdate  No Valid record as of specific date. Current date – sysdate is a default
