Data Changes
Qualitative Distinction
The RxNorm model revolves around the active ingredient, strength, and dose form (i.e., TTY=SCD) for drug products. There are some cases, as identified by those using RxNorm in eprescribing systems and drug formularies, where the RxNorm model groups drugs that, in practice, need to have separate RXCUIs. To allow flexibility in the RxNorm model to handle such cases, RxNorm now includes a Qualitative Distinction (QD) modifier that can be applied as a prefix to SCD and SBD normalized names. Drugs that include the QD have a different RXCUI than the same drugs without the QD, and information about these drugs, including drug descriptions and NDCs, have been split into the appropriate RXCUI.
Here are the concepts with QDs in the August release:
| RXCUI | TTY | String |
|---|---|---|
| 1801282 | SBD | Emollient hydrocortisone acetate 25 MG/ML / Pramoxine hydrochloride 10 MG/ML Topical Cream [Pramosone] |
| 1801281 | SCD | Emollient hydrocortisone acetate 25 MG/ML / Pramoxine hydrochloride 10 MG/ML Topical Cream |
| 1801283 | SCD | Emollient Fluocinonide 0.5 MG/ML Topical Cream |
| 848951 | SBD | Sugar-Free Cholestyramine Resin 4000 MG Powder for Oral Suspension [Prevalite] |
| 1801280 | SBD | Sugar-Free Cholestyramine Resin 4000 MG Powder for Oral Suspension [Questran] |
| 1801279 | SCD | Sugar-Free Cholestyramine Resin 4000 MG Powder for Oral Suspension |
| 993524 | SBD | Smoking Cessation 12 HR Bupropion Hydrochloride 150 MG Extended Release Oral Tablet [Buproban] |
| 993954 | SBD | Smoking Cessation 12 HR Bupropion Hydrochloride 150 MG Extended Release Oral Tablet [Zyban] |
| 1801289 | SCD | Smoking Cessation 12 HR Bupropion Hydrochloride 150 MG Extended Release Oral Tablet |
| 1801295 | SBD | Microencapsulated Potassium Chloride 20 MEQ Extended Release Oral Tablet [Klor-Con] |
| 1801294 | SCD | Microencapsulated Potassium Chloride 20 MEQ Extended Release Oral Tablet |
| 1801299 | SBD | Microencapsulated Potassium Chloride 10 MEQ Extended Release Oral Tablet [Klor-Con] |
| 1801298 | SCD | Microencapsulated Potassium Chloride 10 MEQ Extended Release Oral Tablet |
For each SCD or SBD with a QD, there is an associated attribute in RXNSAT with the attribute name (ATN) of 'RXN_QUALITATIVE_DISTINCTION'. The August release contains the following attributes to match the QD strings found in the SCD and SBD normalized names:
- Emollient
- Microencapsulated
- Smoking Cessation
- Sugar-Free
