Proposal Status/Commentary

USP posts the status of Revisions, Deferrals, Cancellations, Commentary, and Index for each USP–NF and Supplement.

  • Revisions are approved standards that will appear in the publication.
  • Deferrals are items that have been proposed in Pharmacopeial Forum (PF) but are not yet approved by an Expert Committee.
  • Cancellations are items that have been proposed in PF but have been canceled. Canceled items may be re-proposed in a future PF.
  • Commentary is a summary of comments received and the appropriate Expert Committee's responses in cases when proposals advance to official status without being re-published in PF.
  • The Index is a copy of the combined Index for a given Book or Supplement. The Index is posted for informational use only and should not be used for interpretive purposes.

Revisions, Deferrals, and Cancellations generally are posted in advance of posting of the online USP–NF or Supplement. Commentary and Index are posted the same day the online USP–NF, Supplement, or other official text is released.

The Cumulative List of USP–NF Revisions provides updated information on all items approved, deferred, or cancelled during the 2015–2020 Cycle.
