The quality unit should take part in all quality-related matters and review and approve the relevant quality documents. Its main responsibilities should be written down and not handed to others, and should include at least: releasing or rejecting every API, and every intermediate that leaves the company's control; running a release and rejection system for incoming raw materials, intermediates and packing and label stock; reviewing completed batch production and laboratory records of critical steps before an API is distributed; seeing that critical deviations are investigated and closed; approving specifications, master production instructions and every procedure affecting quality; seeing that internal audits happen; approving contract manufacturers of intermediates and APIs; approving changes that could affect quality; signing off validation protocols and their reports; seeing that quality complaints are investigated and closed; seeing that critical equipment is maintained and calibrated under effective systems; seeing that materials are properly tested and results reported; seeing that stability data back up assigned retest or expiry dating and storage conditions; and carrying out product quality reviews.
