New RxNorm Attributes
The Basis of Strength Substance (BoSS) is now explicitly indicated in RxNorm allowing improved alignment with international drug data standards. The new attributes also support computation by including the product strength as discrete numerator and denominator values and units rather than as a string in the RxNorm normalized name. There are seven new attributes associated with the Semantic Clinical Drug Component (SCDC) term type (TTY) in RxNorm.
Here are the seven new attribute names (ATN) in RXNSAT associated with SCDCs in RxNorm:
|Term Type or Attribute||Number|

|Active RXNORM INs||5507|
|Active RXNORM PINs||1504|
|Active RXNORM BNs||4381|
