lui:
  1.  Unique identifier for term (no value provided)

sui:
  1.  Unique identifier for string (no value provided)

rxaui:
  1.  RxNorm atom identifier (RXAUI) or RxNorm relationship identifier (RUI).

stype:
  1.  The name of the column in RXNCONSO.RRF or RXNREL.RRF that contains the identifier to which the attribute
      is attached, e.g., CUI, AUI.

code:
  1.  'Most useful' source asserted identifier (if the source vocabulary has more than one identifier), or a
      RxNorm-generated source entry identifier (if the source vocabulary has none.)

atui:
  1.  Unique identifier for attribute

satui:
  1.  Source asserted attribute identifier (optional - present if it exists)

atn:
  1.  Attribute name. Possible values appear in RXNDOC.RRF and are described on the UMLS Attribute Names page

sab:
  1.  Abbreviation of the source of the attribute. Possible values appear in RXNSAB.RRF and are listed on the
      UMLS Source Vocabularies page

atv:
  1.  Attribute value described under specific attribute name on the UMLS Attribute Names page. A few attribute
      values exceed 1,000 characters. Many of the abbreviations used in attribute values are explained in
      RXNDOC.RRF and included UMLS Abbreviations Used in Data Elements page

suppress:
  1.  Suppressible flag. Values = O, Y, or N. Reflects the suppressible status of the attribute. N - Attribute
      is not suppressed. O - Attribute is suppressed at source level. Y - Attribute is suppressed by RxNorm
      editors.

cvf:
  1.  Content view flag. RxNorm includes one value, '4096', to denote inclusion in the Current Prescribable
      Content subset. All rows with CVF='4096' can be found in the subset.
