Pharmaceutical packaging market

Traditionally, the pharmaceutical packaging industry is categorized into three segments: primary, secondary, and tertiary packaging. Primary packaging, or consumer packaging, directly interacts with drug products.

Therefore, understanding the potential interactions between primary pharmaceutical packaging containers and their contents is crucial. During the primary research and development stage, efforts are made to confirm drug product stability and compatibility to ensure that the packaging does not alter the chemical composition of the drug.

Fun Fact: The material that allows the air to stay inside your tires, ensures that air does not enter your medication.

Secondary pharmaceutical contract packaging services involve packaging that consolidates individual units of primary packaged goods, often assembling them into multipacket units. Unlike primary packaging, secondary and tertiary packaging is not intended to hold the drugs but to facilitate their delivery in mass quantities to the point of sale or end user.

As you might have guessed, primary packaging is thus the most important of the three packaging categories. According to the latest regulation, call Annex 1 which was released in mid-2023, primary packaging has been defined as such “Primary packaging containers and components should be cleaned using validated processes to ensure that particulate, pyrogen and bioburden contamination is appropriately controlled.” The evolving regulatory landscape requires pharma and biotech companies to partner with a true expert who can help them navigate the new regulations successfully. Supplier components may be part of the overarching sterile manufacturing process and contamination control strategy; however, it is the responsibility of the finished product (drug/biologic) manufacturer to comply with the regulation.”

Now you might be wondering what are the different components that make up the primary packaging. These include:

• Medicinal product containers: bottles, pill bottles and dispensers in glass and plastic
• Pharmaceutical packaging closures: stoppers and plastic or aluminum caps
• Medical devices: drug delivery and dispensing accessories
