Maintaining the sterility and efficacy of pharmaceutical products is paramount. Even the smallest breach in packaging can compromise a drug's integrity, leading to contamination or degradation. Helium leak testing offers a highly sensitive and reliable method for ensuring the integrity of pharmaceutical packaging.

Helium leak testing is a non-destructive Container Closure Integrity Test (CCIT) used to detect leaks in sealed systems. Helium, being the smallest and lightest gas molecule, readily permeates even minute leaks. The basic principle involves introducing helium into the package or placing it in a helium-rich environment. A highly sensitive detector then measures the helium escaping from any leaks present. Leak detection is achieved through mass spectrometry, where the detector isolates and measures the specific signal of helium ions.

Why is Helium Leak Testing Important for Pharmaceutical Packaging?

Pharmaceutical packaging plays a vital role in protecting the sterility and efficacy of drugs. Even microscopic leaks can allow for the ingress of contaminants like moisture, oxygen, or microorganisms. This can lead to:

• Product degradation: Exposure to air or moisture can alter the chemical composition of a drug, rendering it ineffective or even harmful.
• Microbial growth: Leaks can allow for the introduction of bacteria, fungi, or other microorganisms, posing a serious health risk.
• Reduced shelf life: Compromised packaging can shorten the shelf life of a drug, leading to product waste.

Helium leak testing offers several advantages over other leak detection methods:

• High sensitivity: Helium leak testing can detect leaks significantly smaller than those identified by other methods.
• Non-destructive: This technique does not damage the packaging, allowing for post-testing evaluation and analysis.
• Broad applicability: Helium leak testing is suitable for a wide range of pharmaceutical packaging materials and formats.

The pharmaceutical and medical device industries are witnessing a surge in the development and use of combination products. These products integrate a drug, biologic, or medical device into a single entity, offering improved patient convenience and therapeutic efficacy. However, ensuring the safety and efficacy of these products requires robust Container Closure Integrity testing (CCIT) strategies. This blog delves into the world of combination products, explores the challenges associated with their CCI testing, and introduces MicroCurrent High Voltage Leak Detection (HVLD) technology as a reliable solution.

The rise of combination products is driven by several factors:

• Enhanced treatment options: Combining drugs and devices allows for targeted delivery and improved therapeutic effects.
• Patient convenience: Pre-filled syringes, auto-injectors, and inhalers offer user-friendly administration methods.
• Reduced healthcare costs: Combination products can streamline treatment processes and potentially lower overall costs.

However, ensuring the integrity of the packaging in combination products presents unique challenges:

• Complex design: Integration of different components can introduce potential leak paths.
• Material compatibility: The packaging materials need to be compatible with both the drug and the device.
• Stringent regulations: Regulatory bodies require robust evidence of package integrity throughout the product lifecycle.

Container Closure Integrity Testing of Combination products using MicroCurrent HVLD Technology

PTI's MicroCurrent HVLD technology is a non-destructive and non-invasive Container Closure Integrity Test (CCIT) method that leverages unique voltage characteristics to inspect a wide variety of parenteral products, including complex combination products. This technology is applicable to pre-filled syringes, vials, cartridges, ampoules, BFS, bottles, and pouches. The MicroCurrent HVLD test method can accurately detect the presence and location of defects such as pinholes, micro-cracks, stopper/plunger leaks, non-visible leaks under crimping, and many others.

To ensure Container Closure Integrity, the method scans a non-conductive sealed container using electrode probes. Any defects in the package will cause a resistance differential and alter the current flow within the container. Unlike traditional HVLD technologies, MicroCurrent HVLD uses approximately 50% less voltage and exposes the product and environment to less than 5% of this reduced voltage. This lower exposure voltage not only minimizes the risk to the product but also significantly reduces ozone production during operation. As one of the most sensitive CCI technologies available, it is particularly suited for high-risk combination products.

Benefits Of Microcurrent HVLD Technology

• Non-destructive, non-invasive, no sample preparation
• High level of repeatability and accuracy
• Effective across all parenteral products, including extremely low conductivity liquids
• Low voltage exposure to the product and environment
• Listed in USP Chapter <1207> as recommended method for parenteral liquid package integrity testing .
• Robust method and approximate 3x Signal-Noise-Ratio for a wide range of product classes and package formats
• Simplifies the inspection and validation process
• Offline and automated online inspection
