Friday, December 15, 2017 - 11:00am to 12:00pm

Check your membership status here

IPEC-Americas and IPEC Europe have jointly published a guide for excipient makers and users on co-processed excipients. This guide offers best practice and voluntary guidance on the development, manufacture and use of co-processed excipients and provides support to both manufacturers and users of co-processed excipients.

Co-processed excipient users are responsible for assuring fitness for purpose and that the co-processed excipient and its components are manufactured to acceptable good manufacturing practice (GMP) standards. The guide facilitates communication between excipient users and suppliers regarding the safety information required for regulatory filing for a product containing a novel co-processed excipient.
