The pharmaceutical industry continues to bring breakthroughs in the field of new drugs and drug delivery systems amidst the increased scrutiny of the regulators. The packaging acts as the primary sterile barrier in drug delivery systems that safeguard the drug product through its life cycle. The efficiency of the primary sterile barrier and the functional components are of utmost importance to patient safety.

Packaging plays a significant role in the drug delivery system. Packaging provides information regarding the manufacturer’s name, price, date of manufacturing and expiry, dose or strength, ingredients, etc. Blister packaging is a type of packaging format specially designed for tablets and capsules made by heating and shaping a plastic sheet into the 'blister,' which is entirely covering the object, into a bubble or a pocket. Several types of plastic materials like Polyvinyl chloride (PVC), Polyethylene terephthalate (PET), Amorphous polyethylene terephthalate (APET), High-density polyethylene (HDPE), etc. and aluminum sheets or foils are used in blister packaging. Blister packages can offer barrier protection and some tamper resistance to shelf-life requirements.

The quality testing of medical device packaging is highly significant in ensuring the safe delivery of medical devices from their place of origin to the market. Guidance documents such as ISO 11607 provide a list of methods that have the capability to improve the package quality testing of today’s capability.

The VeriPac 465 performs leak detection based on the basic principles of physics and does not require the use of trace gasses or sample preparation to perform the test. The VeriPac 465 core technology is based on the ASTM vacuum decay leak test method (F2338) recognized by the FDA as a consensus standard for package integrity testing. This test method was developed using VeriPac leak test instruments. The VeriPac 465 combines technological innovation and practical adjustments to patented dual vacuum transducer technology, PERMA-VAC, to make it the most sensitive and versatile vacuum-based leak detection technology to date. Through the introduction of unique test cycles, pneumatic controls and processing algorithms, the VeriPac 465 is establishing itself as the foremost vacuum-based leak test for parenteral products.

The most current model, the Seal Integrity Monitoring System (SIMS) 1915+, is the ideal choice for your helium-based leak detection system. Compared to conventional vacuum bubble and dye penetration test methods, packages can be quantitatively tested using helium as the tracer gas that ensures higher levels of accuracy. Such an approach allows a comparison between multiple packaging materials and forms production line settings and stability storage conditions, supporting the entire lifecycle.

There have been many advances over the past decade in terms of drug product delivery methods. As a result, key developments like unique cartridge based delivery systems have become common. It is well documented that Helium mass spectrometry is most suited for non-porous packaging such as vials and syringes. The same methodology can also be applicable to cartridge based delivery systems. In most cases the key to success is the development of a text fixture device designed and manufactured to the specific cartridge system being testing. These custom fixtures for helium leak detection can be designed to isolate specific areas of interest in the cartridge system.

Integrity testing of foil pouches offers a unique set of challenges. In most packaging processes that involve foil as the product barrier there is a concern about the incidence of punctures in the foil. These defects (typically called micro-voids) can be created as the foil is being rolled in thin sheets and tiny particles are inadvertently rolled into the foil. The most common defect is caused from the handling of the packages during the assembly of the foil and insertion of the drug product.

A helium based test method for verifying the integrity of a blister card holding drug product has been proven to be the most effective approach due to the extreme sensitivity offered. The test method relies on detecting helium sealed in the package system as it escapes through micro-channels in the package. A test sequence begins by placing the package in the test fixture and a vacuum is quickly drawn. The resulting pressure differential causes helium to escape through potential holes or cracks in the package.

Bottles come in a wide array of sizes and configurations, reflective of their diverse use in the health sciences industry. Typically, they exhibit a screw top closure threaded onto the bottle mouth, though sealing properties ranges from elastomeric liners, to o-rings, to induction seals and reliance on plastic-to-plastic contact and compression. One specific trend is the increase in need to test sterile bulk containers or sterile API containers. As the industry continues to move toward outsourcing or even insourcing through a network of suppliers or sites, transport of sterile drug product or API is becoming increasingly common. These types of containers are traditionally challenging to test, but can be qualified prior to use or as a proof of concept using helium leak detection.

With the advent of more advanced drug development for a wide variety of injectable compounds and an increasing preference for self-administration, prefilled syringes are the largest parenteral package growth sector. In many ways, the prefilled syringe is more complex and intricate in comparison to a traditional vial, a sealed ampoule, or bottles with screw top closures. They have multiple sealing sites that require integrity, but there is also a functionality piece associated: the syringe plunger must be able to deliver a dose, and thus, is movable.

Parenteral products, specifically Vials, both glass and, increasingly, polymeric vials, represent one of the most common package systems historically tested by helium leak detection, largely due to their continued dominance as a package system for high-potency drugs requiring utmost protection. The primary sealing interface of a traditional vial system is between the elastomeric closure and land seal of a vial, physically compressed together by a crimped aluminum seal.

Helium leak detection (HeLD) is routinely used and widely accepted for applications that require the utmost leak sensitivity.

The pharmaceutical industry continues to bring breakthroughs in the field of new vaccines and drug delivery systems amidst the increased scrutiny of the regulators. The packaging acts as the primary sterile barrier in drug delivery systems that safeguard the drug product through its life cycle. The efficiency of the primary sterile barrier and the functional components are of utmost importance to patient safety.

The United States Pharmacopeia USP 1207 guidance has been revised, encouraging the preference to deterministic, quantitative, and reliable non-destructive technologies to comply with quality standards.

The pharmaceutical industry continues to lead industries in terms of quality requirements and the value of data. The shift to more automated processes is less about the cost of human capital, but more about the pursuit of quality. The European Medicines Agency (EMA) updated Annex 1, driving for 100% inspection on fused containers and appropriate quality test measures for applications based on level of risk. The United States Pharmacopeia (USP) revamped Chapter 1207 on container closure integrity (CCI) to be prescriptive of deterministic technologies and encourages a deeper understanding of a container’s CCI requirements. The FDA continues to drive a ‘quality culture’ agenda versus a ‘compliance culture’, and the FDA has been explicitly targeting data integrity as a campaign for assuring quality. Every regulatory and guidance body is driving towards more reliable and accurate test methods.

Container Closure Integrity (CCI) is defined as whether the container is maintaining a sterile barrier. Intravenous (IV) bags are crucial in delivering fluids or medication quickly. Leaking parenteral packages are considered an extremely high risk as they deliver fluid directly into the bloodstream and have a high potential for microbial growth, requiring the need for sensitive and reliable CCI testing.
