Data Changes

Prescribable Names:
Building upon last month's release of prescribable names (TTY=PSN), the August release includes prescribable names for many drugs with cream and lotion dose forms.

RXNREL Suppress Values:
The SUPPRESS field in RXNREL is no longer being populated. In previous RxNorm releases, while most rows included no SUPPRESS value, some rows mistakenly included a SUPPRESS='N' value. Because RxNorm editors do not suppress any relationships in RXNREL, the SUPPRESS field is no longer being populated. The SUPPRESS field for all rows is null.
