RxNorm Current Prescribable Content Release Notes

June Release - 06/04/2012

This RxNorm Current Prescribable Content release is consistent with the 2012AA UMLS Metathesaurus release. For additional information about RxNorm releases, including scripts for loading the RxNorm data into Oracle and MySQL databases, read the RxNorm Technical Documentation.

Data Changes

This release of RxNorm includes a new attribute. The new RXTERM_FORM attribute provides dose form strings, many of which are abbreviated, that are useful for drug application interfaces. These attributes are associated with SCD and SBD concepts. For example, the SCD 'Diazepam 2 MG Oral Tablet' has an ATN=RXTERM_FORM attribute with a value (ATV) of 'Tab'.

This release also includes changes to the dose form groups (DFGs). The names of many of these groups have changed slightly (e.g. the addition of "Product" to the end of the string). There are also more than 20 new dose form groups, all of which are listed in Appendix 3. Changes to these DFGs have been propagated to the associated SCDGs/SBDGs. RXCUIs/RXAUIs for these concepts remain unchanged.

You can find more information about these changes in the RxNorm Technical Documentation.
