New Revision Markup for Reference Changes in USP–NF

Type of Posting: General Announcement

Posting Date: 31–Jul–2014

USP and its Expert Committees periodically deem it necessary to modify general chapter titles or similar text that may be referenced in other standards throughout the USP–NF. When this occurs, USP staff undertakes a rigorous process for identifying and updating such references. These updates may occur through a routine revision, or, in cases in which an update appears to present no significant change in the affected standard, through a direct update of the reference in that standard without providing an opportunity for notice and comment. In all cases, USP will publish on its website a notice indicating the source change, any resulting references, and whether those references will be updated through a routine revision or a direct update. Updates made through direct publication in the USP–NF will be clearly identified by symbols and shading in the print and electronic publications.

Because some updates to references may be assigned delayed official dates to ensure that all related revisions become official together, the revision markup used to identify the reference updates will be dependent upon when the change will become official. Updates becoming official at the same time as the USP–NF Book in which they are published will be identified with the following revision markup, where CN denotes Compendial Notice:

  • Changed text (CN 1–May–2015)

Updates becoming official on a future date than the USP–NF Book in which they are published will be identified with the following revision markup:

  • Changed text (Official 1–Dec–2015)
