Data Changes

Beginning with this release, RXNCONSO.RRF will include a new SUPPRESS value of ‘E’ (editor suppressed) for some SAB=RXNORM drug names. The SUPPRESS=E flag is applied to unquantified TTY=SCD/SBD drug names with no NDCs (i.e., not prescribable) that have related quantified TTY=SCD/SBD drug names. The SUPPRESS=E flag indicates that a drug is not prescribable, and that you should look for the related quantified drug(s) instead.

Unquantified - Has no quantity factor
Fluticasone propionate 0.1 MG/ACTUAT Dry Powder Inhaler [Flovent]

Quantified - Has quantity factor that represents a strength, a unit of time, or a quantity of dosages depending upon the dose form.
60 ACTUAT Fluticasone propionate 0.1 MG/ACTUAT Dry Powder Inhaler [Flovent]

In the above examples, the unquantified ‘Fluticasone propionate 0.1 MG/ACTUAT Dry Powder Inhaler [Flovent]’ has a SUPPRESS=E flag. This drug has no NDCs and is not prescribable; however, its related quantified drug, ‘60 ACTUAT Fluticasone propionate 0.1 MG/ACTUAT Dry Powder Inhaler [Flovent]’, has NDCs and is prescribable.

Unquantified drug names with the following dose forms may have SUPPRESS=E flags:

  • Extended Release Capsule
  • Extended Release Enteric Coated Capsule
  • Extended Release Enteric Coated Tablet
  • Extended Release Suspension
  • Extended Release Tablet
  • Transdermal Patch
  • Prefilled Syringes
  • Prefilled Applicator
  • Nasal Inhaler
