In the latest news regarding the US Pharmacopeia’s proposed limits and test changes for heavy metals, the organization is expected to post new information on its website regarding its plans to revise General Chapter <231> based on its June 2–3 USP PNP stakeholders meeting.

Some of the reported changes include a second stimuli article (the first was issued last fall and received a tremendous amount of industry comments), a separate test methods chapter, and a separate dietary supplements chapter. USP is expected to post official recommendations from its stakeholders meeting on its website soon, at which point PharmTech will provide a direct link.
