rxcui:
  1.  RxNorm Unique identifier for concept (concept ID)

lat:
  1.  Language of Term

ts:
  1.  Term status (no value provided)

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

stt:
  1.  String type (no value provided)

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

ispref:
  1.  Atom status - preferred (Y) or not (N) for this string within this concept (no value provided)

rxaui:
  1.  Unique identifier for atom (RxNorm Atom ID)

saui:
  1.  Source asserted atom identifier [optional]

scui:
  1.  Source asserted concept identifier [optional]

sdui:
  1.  Source asserted descriptor identifier [optional]

sab:
  1.  Source abbreviation

tty:
  1.  Term type in source

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.)

str:
  1.  String

srl:
  1.  Source Restriction Level (no value provided)

suppress:
  1.  Suppressible flag. Values = N, O, Y, or E. N - not suppressible. O - Specific individual names (atoms)
      set as Obsolete because the name is no longer provided by the original source. Y - Suppressed by RxNorm
      editor. E - unquantified, non-prescribable drug with related quantified, prescribable drugs. NLM strongly
      recommends that users not alter editor-assigned suppressibility.

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.
