The Odd Couple – Part 5: Authoring the Container Closure Systems for Packaging of Drug Substance and Product Modules

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.
