Simplifying Parenteral Product Inspection: PTI's Solutions

The safety and efficacy of parenteral drugs – medications administered through injection – hinge on meticulous quality control throughout the manufacturing process.? One critical aspect is ensuring package integrity, which refers to the container's ability to maintain the sterility and stability of the product.? This blog post delves into the importance of package integrity for parenteral products and provides a detailed exploration of automated inspection solutions offered by PTI.

Why Parenteral Products Package Integrity is Critical?

Unlike oral medications that can tolerate some environmental exposure, parenteral drugs are typically sterile and highly sensitive. They require a hermetic seal to maintain this sterility and ensure the product's potency throughout its shelf life.? Any breach in the container, even microscopic, can have severe consequences:

Microbial Ingress: A compromised container seal can act as a gateway for microorganisms like bacteria, mold, or fungi to enter the product. This contamination poses a significant health risk to patients, potentially leading to life-threatening infections.

Product Degradation: Exposure to air, moisture, or light can alter the drug's chemical composition. This degradation can render the medication ineffective or even create harmful byproducts. Furthermore, changes in moisture content can affect the drug's stability, impacting its release profile and potentially leading to under- or over-dosing.

The Limitations of Traditional Inspection Methods

Traditionally, package integrity has been assessed through manual visual inspection or methods such as the dye ingress test, also known as the blue dye text.? Inspectors meticulously examine containers for cracks, tears, or other visible defects in the container or closure.? Dye Ingress is a destructive test method and also highly subjective.? These traditional methods have several limitations:

·???????? Subjectivity: The inspector's interpretation can influence the outcome, leading to inconsistencies and potential missed defects.

·???????? Limited Detection: Visual inspection struggles to detect microscopic leaks or imperfections that may compromise integrity.

·???????? Time-Consuming: Manually inspecting large batches of containers can be slow and laborious, impacting production efficiency.

The Advantages of Automated Inspection

Automated inspection systems offer a superior alternative to traditional methods.? These systems utilize sophisticated, non-destructive techniques to meticulously examine containers for even the most minute defects. Another important point is choosing a technology that offers bi-lateral scalability from the laboratory to the production line, as well as from production, back to the lab.? A very distinct advantage to achieve a high level of CCI throughout the product lifecycle.?

Here's how automated inspection offers distinct advantages:

·???????? Objectivity: Automated systems rely on pre-defined parameters and sensitive instruments, eliminating human subjectivity and ensuring consistent results.

·???????? Enhanced Detection: These systems can detect leaks, material inconsistencies, and closure imperfections far beyond the capabilities of the human eye.

·???????? Increased Efficiency: Automated systems can inspect large batches of containers quickly and efficiently, significantly reducing inspection time and labor costs.

·???????? Improved Data Tracking: Automated systems can generate detailed reports on inspection results, allowing for better data tracking and quality control trend analysis.

Techniques for Automated package integrity testing

1.E-Scan RTX Technology

The E-Scan RTX is a fully automated container closure integrity testing (CCIT) solution for pre-filled syringes. It uses MicroCurrent HVLD technology, a non-destructive testing method that is highly sensitive to even the smallest leaks and defects. MicroCurrent HVLD technology works by applying a high-voltage, low-current signal to the syringe. The signal creates an electric field around the syringe, which is disrupted by any leaks or defects in the packaging. The E-Scan RTX detects the disruption in the electric field and generates a signal that indicates whether the syringe has passed or failed the test. The E-Scan RTX is a highly efficient solution for automated testing in the laboratory to high-volume manufacturing.

Features of E-Scan RTX

·???????? Fully automated CCI testing for pre-filled syringes

·???????? MicroCurrent HVLD technology for high sensitivity and accuracy

·???????? High throughput (hundreds of syringes per hour)

·???????? Easy integration into existing production lines

·???????? Scalable from the lab to production

2. VeriPac LPX Technology:

The VeriPac LPX is a fully automated CCI testing solution for a wide range of parenteral packaging formats, including vials, ampoules, and cartridges. It uses vacuum decay technology, a non-destructive testing method that is highly reliable and accurate. Vacuum decay technology works by creating a vacuum inside the packaging container and then measuring the rate at which the pressure increases over time. A leak in the packaging will cause the pressure to increase more quickly, indicating that the package has failed the test. The VeriPac LPX can be used for batch release testing or inline testing. It is highly versatile and can be configured to test a variety of packaging formats and sizes.

Features of VeriPac LPX

·???????? Fully automated CCI testing for a wide range of parenteral packaging formats

·???????? Vacuum decay technology for high reliability and accuracy

·???????? High throughput

·???????? Easy integration into existing production lines

·???????? Scalable from the lab to production

Both the E-Scan RTX and the VeriPac LPX are valuable tools for pharmaceutical manufacturers who are looking to improve the safety and quality of their parenteral products. These automated CCI testing solutions can help manufacturers reduce risk, improve compliance, and increase profitability.
