Coordination of Official New Monographs, Revisions, and USP Reference Standards

February 20, 2006

USP is pleased to announce a change in the way that we coordinate the adoption of official new monographs and revisions with the release of the required reference standards. Beginning with the Second Supplement to USP29–NF24, new monographs and revisions to existing monographs will not be published as official standards until the required USP Reference Standards are available for sale. Monographs may be made available on a case-by-case basis without USP Reference Standards availability, but this should be a rare occasion. This effort will temporarily slow the presentation of new monographs that are published in the USP–NF, but will ultimately lead to better public standards.
