Complete guide to primary packaging in pharmaceutical industry: roles, types and current regulations

In the pharmaceutical industries, primary packaging plays an essential role in ensuring the protection, stability, and integrity of the formulas with which they are in direct contact.

Pharmaceutical primary packaging as a glass ampoule to better preserve drug products.

In the pharmaceutical industries, primary packaging plays an essential role in ensuring the protection, stability, and integrity of the formulas with which they are in direct contact.

Compared to other drug packaging types in the industry, the design of pharmaceutical primary packaging is one of the most controlled and regulated (especially subject to GMP pharmaceuticals, “Good Manufacturing Practices”) because it is in direct contact with the drug. As it also serves to transport medicines, this type of packaging must be extremely secure to protect the health of the end consumers (the patients).

Among the pharmaceutical packaging types commonly used options include glass ampoules, blister packs, sachets, and pipettes. These differ from secondary packaging, which serves as the external wrapping of a drug.

    1. Definition and role of pharmaceutical primary packaging

    Primary packaging is the first level of protection for products from any source.

    When applied to the pharmaceutical market, it is in direct contact with a drug’s formula. Its main role is to ensure the integrity, preservation, quality, and safety of the product.

    Primary pharmaceutical packaging thus plays a major role in the presentation, use, and protection of the drug against any form of alteration, contamination, or external factors (humidity, oxygen, UV, etc.)

    Last but not least, the primary packaging of drugs obviously ensures the traceability and information of the product.

    2. Types of primary pharmaceutical packaging

    a. The main types of pharmaceutical primary packaging

    In pharmaceutical use, there are several types of packaging depending on the dosage forms.

    The primary packaging of liquid formulas:

    • Glass drinkable ampoules
    • Vials
    • Bottles
    • Tubings
    • Pipettes
    • Sachets
    • Pre-filled syringes

    The primary packaging of solid formulas, such as tablets, capsules, and gel caps:

    • Blister packs
    • Bottles

    The primary packaging of powder or granule formulas:

    • Sachets
    • Bottles: especially for formulas that need to be dissolved with the addition of water

    b. The materials used in the design of primary pharmaceutical packaging

    The most commonly used materials in the manufacture of primary pharmaceutical packaging are: glass, plastic, and aluminum.

    Glass, such as borosilicate glass (type I), and soda-lime glass (type III), are respectively valued for their chemical and thermal resistance, and their protection against UV light.

    Our double-tip drinkable ampoules are ideal solutions for your pharmaceutical and nutraceutical formulas. SFAM favors these glasses for the manufacturing of its double-tip glass ampoules, in order to ensure the protection, quality, and safety of the products.

    3. Current regulations for primary packaging in pharmaceutical industry: key information

    Certain essential information, required by regulations, must be included on primary packaging, particularly in the pharmaceutical industry:

    • The brand and name of the medication or dietary supplement
    • The pharmaceutical formulation (for medications)
    • The composition with detailed dosages and concentrations of active substances per unit of intake
    • The manufacturing batch number
    • The expiration date
    • The instructions for administration and use of the product
    • Safety information including precautions for use and contraindications

    4. Current regulations for primary pharmaceutical packaging: manufacturing standards and rules

    a. The quality norms

    Strict standards govern the production of primary packaging to ensure the safety and efficacy of products. These standards include:

    • The European Pharmacopoeia: defining standards for materials used, such as borosilicate glass.
    • The ISO 15378 norm: which specifies the requirements for GMP, Good Manufacturing Practices for primary packaging materials.

    b. The regulations

    While some regulations vary by region, there are quality standards established by the International Pharmacopoeia:

    • Compliance with GMP, Good Manufacturing Practices. These practices involve manufacturing products according to very strict procedures. The UNI EN ISO 15378 : 2018 standard specifies the expected requirements at all stages of the manufacturing process, from design to logistics, including the manufacturing of the pharmaceutical product.
    • Compatibility tests to ensure that the packaging and its contents do not interact.
    • Quality controls.

    In addition, there are equally strict rules for accessories used in the administration of medications. This includes medical devices detailed by Regulation (EU) 2017/745, which must meet strict safety criteria.

    Primary packaging is therefore essential for ensuring the safety, efficacy, and quality of pharmaceutical products. The materials used, types of closures, mandatory labeling, and quality standards are all critical factors.

    Committed to meeting these requirements, SFAM provides innovative, high-quality solutions with its double-tip glass ampoules, tailored to the needs of the pharmaceutical and dietary supplement markets.
