Although packaging may seem like an activity that belongs to the distribution side of things, it’s a manufacturing operation as far as the GMP is concerned. This also applies to labelling.
Packaging and labeling are considered Good Manufacturing Practice (GMP) activities because they are critical steps in the manufacturing process that ensure the correct product is contained in the appropriate package and is accurately labeled. This is essential for ensuring patient safety, product identity, strength, purity, and quality. GMP covers all aspects of production from the starting materials, premises, and equipment to the training and personal hygiene of staff.
Specifically, GMP for packaging and labeling includes, but is not limited to:
- Ensuring that labels are correct and legible, to avoid mix-ups and misidentification of products.
- Verifying that packaging materials are suitable to protect the product from contamination and degradation over its shelf life.
- Ensuring that the product is packaged and labeled according to the approved specifications and in a way that maintains its quality throughout the shelf life.
Good Distribution Practice (GDP), on the other hand, starts once the product has been released for distribution and is concerned with the proper distribution of medicinal products for human use. GDP ensures that the level of quality determined by GMP is maintained throughout the distribution network, so that authorized medicines are distributed to the end user without any alteration of their properties.
GDP activities include:
- The proper transportation and handling of pharmaceutical products.
- The storage of pharmaceutical products in suitable conditions.
- Ensuring that the distribution of pharmaceutical products is conducted in accordance with the legal requirements and with an adequate record-keeping system.
In essence, GMP is focused on the correct creation and packaging of a safe and high-quality product, while GDP ensures that the product's quality and integrity are maintained through the entire supply chain until it reaches the consumer.
