On the basis of comments received to date, USP is extending the comment deadline for the PF 38(6) revision proposal for the Heparin Sodium monograph by 60 days to March 31, 2013. The purpose of this extension is to allow interested stakeholders ample time to evaluate the proposed changes, especially the new Molecular Weight Determinations test which uses a new USP Heparin Sodium Molecular Weight Calibrant RS. This reference material is in the final stages of development.

To receive notification of the RS release, interested stakeholders are encouraged to enroll in the USP Reference Standards Release Notification Service.

Any revisions to the monograph will be considered for inclusion in the USP 37–NF 32.
