In January 2006, FDA published a final rule that amended the requirements for the content and format of approved labeling (prescribing information) for human prescription drug and biological products.[1]  The new prescribing information format is intended to make it easier for health care professionals to access, read, and use to make prescribing decisions.

 

The rule requires the following statement to appear under the Indications and Usage section of Highlights if a drug is a member of an established pharmacologic class:[2]

 

“(Drug) is a (established pharmacologic class) indicated for (indication(s)).”

 

The pharmacologic class codes for active moieties in FDA approved human prescription drug products are included in the downloadable .zip file below.

The list of pharmacologic class indexing terms will be regularly revised to ensure that the most up-to-date information is available to the public.
