Update: Pharmacopeial Forum 43(2) Comment Deadline Extended

USP is extending the comment deadline for Pharmacopeial Forum (PF) 43(2) [Mar.-Apr. 2017] from May 31, 2017 to July 31, 2017, coinciding with the deadline for PF 43(3) [May-Jun. 2017].

USP discovered a technical issue affecting the functionality of the advanced search function of the publication, which has now been addressed.  Users who directly access content through the table of contents rather than the search functions were not affected by this technical issue. The extension of the comment deadline is intended to assure that users who may have been affected by this issue still have access to the entire 90-day notice and comment period now that full functionality has been restored. Other issues of Pharmacopeial Forum were not affected.

USP regrets any inconvenience that this issue may have caused to users.

It has come to our attention that a pop up notice appears when a user attempts to send comments or questions that states the comment period has closed for PF 43(2). You may disregard this statement and continue submitting comments or questions by selecting “OK” in the pop up box. They comment period for PF 43(2) is still open through July 31, 2017.

We are sorry for any confusion this may have caused.

Should you have any questions, please contact Caroline Martin, Director, Publications (301-816-8521 or
