In-Process Control Procedure in Pharmaceutical Industry
These are checks that are carried out before the manufacturing process is completed. The function of in-process controls is monitoring in order to comply with the specifications .It may include control of equipment and environment too. Rejected in-process materials should be identified and controlled under a quarantine system designed to prevent their use in manufacturing .Written procedure should be established and followed that describe the in-process controls and tests.
