Type of Posting: Notice of Intent to Revise

Posting Date: 24–Feb–2012

Targeted Official Date: Interim Revision Announcement, 01–Nov–2012

Expert Committee: Monographs—Small Molecules 3

In accordance with section 7.05(c) of the 2010–2015 Rules and Procedures of the Council of Experts, this is to provide notice that the USP Monographs—Small Molecules 3 Expert Committee intends to revise the Glycopyrrolate monograph. Using a flexible monograph approach, a second procedure for Organic Impurities is being added to the monograph, to control the potential impurities by a different synthetic route. This newly added procedure calls for the use of a UHPLC system, which reflects USP’s attempt to introduce new technologies into compendial standards.

It is anticipated that the revision will be published as a Proposed Interim Revision Announcement in PF 38(3) [May–Jun. 2012] pursuant to section 7.02 of the Rules and Procedures. Interested parties are encouraged to submit comments on the proposal.
