"The IPEC Federation published Version 3 of its Qualification of Excipients for Use in Pharmaceuticals Guide and Checklist (2026), updating the original 2008 edition to align with current regulatory expectations. The guide, widely used globally, emphasizes qualification of excipient suppliers to secure the supply chain after recent adulteration incidents. It lays out best practices for relationships between suppliers and users and offers practical recommendations to address common challenges. The accompanying checklist provides a quick reference for topics to consider during excipient qualification. Access will be initially exclusive to IPEC members for three months on IPEC’s website and national/regional sites."
