Publication and Comment Schedule

All official revisions are published in the annual edition or Supplements to USP-NF (twice yearly). Between these publications, official revisions are published in Pharmacopeial Forum (PF) in the Interim Revision Announcement section and incorporated in the upcoming Supplement or book. They may also be published as Revision Bulletins on www.usp.org in the "New Official Text" section. The official publication in which an Interim Revision Announcement is incorporated depends upon publication deadlines. The electronic version of USP-NF is updated as each Supplement becomes available and, therefore, contains all official text up to and including the contents of the latest Supplement. The table below outlines the publications and their release and official dates, and the book or supplement which supersedes them.

INTERIM REVISION ANNOUNCEMENTS

The USP welcomes and encourages interested parties to submit comments and data regarding potential, proposed, or adopted (official) standards. In accordance with the Rules and Procedures of the 2005-2010 Council of Experts, USP has implemented a 90-day comment period by providing a deadline for each issue of PF unless otherwise stated in the individual briefing. The listing of comment period deadlines and the targeted official publications appears below.
