PF is the bimonthly online journal through which USP develops and revises standards for the United States Pharmacopeia and the National Formulary (USP–NF) by a process of public review and comment. Changes and additions to USP–NF standards are first proposed in PF to invite public comment.
Now a Free, Online-only Resource
To encourage and broaden participation in the standards-setting process, USP transitioned PF from a subscription-based print and online publication to a free, online-only resource with the release of PF 37 (1) on January 3, 2011.
New issues are posted online every two months and the comment period is 90-days and ends on the last day of the month (View current PF Publication and Comment Schedule).
Information Featured in PF
To make it easier for users to identify and respond to proposed changes to USP–NF standards, PF now contains only proposals for which USP is seeking public comment and information, including:
* In–Process Revisions
* Proposed Interim Revision Announcements (IRAs)
* PDG Harmonization Proposals (Stage 4)
* Stimuli Articles
(Please note: a one-time registration is required to access PF.)

In addition, PF provides access to previously published issues of PF Online dating back to 2002. Other information previously in PF, including official text (final IRAs), is now published on the USP website or will be included in future publications.
