Container closure systems refer to the sum of packaging components that together contain and protect the dosage form. This includes primary packaging components and secondary packaging components, if the latter are intended to provide additional protection to the drug product. The packaging information in the chemistry, manufacturing, and controls section usually includes a description of the components, the assembled packaging system and any precautions needed to ensure the protection and preservation of the drug substance and drug product during their use.

The acceptance criteria and tests conducted for the excipients should be reviewed relative to the preformulation experimental results. The acceptance criteria for the excipients should consider those qualities critical to the drug product performance and manufacturing operation as described earlier in formulation development.

An overview of the quality assurance aspects of the manufacturers may provide insight into the viability of the process. Although not required to be included in the application, a request for the report of the most recent cGMP manufacturing inspection from the US Food and Drug Administration (FDA) and/or European Union (EU) agencies enable a broad overview of the cGMP compliance aspects of the facilities.

For the purposes of this blog series, it will be necessary to produce an admittedly unbalanced summary that shortchanges some sections of the Quality Module but that includes considerable discussion of other sections that can largely influence the ultimate success or failure of an application. I have therefore focused discussion on selected aspects from a remarkably diverse and technical exercise, which is the production of the CTD Quality Module.
