For decades, ensuring the safety and effectiveness of pharmaceutical products has required a meticulous quality control process. With the increasing complexity of pharmaceutical formulations and the demand for higher standards, traditional quality assessment methods present significant gaps. Enter KA Imaging, an innovator in X-ray imaging technology, which is redefining non-destructive testing (NDT) in the pharmaceutical industry. This article will provide an overview of quality control for the pharmaceutical industry while diving into the impacts of KA Imaging’s NDT solutions: The Reveal 35C™ X-Ray Detector, BrillianSe™ X-Ray Detector and InCiTe™ 3D X-Ray Microscope.
The Role of Quality Control in Pharmaceutical Manufacturing
Quality control is critical in the pharmaceutical industry, where product integrity directly impacts patient health. Pharmaceutical manufacturing involves numerous processes ranging from raw material inspection to final product and packaging integrity testing, which requires extensive quality control at every stage. This level of quality control is mandatory for detecting any inconsistencies or defects and ensuring that every batch meets regulatory standards.
Pharmaceutical companies must adhere to Good Manufacturing Practices (GMP), which outline the processes required to ensure product quality and safety. Quality control teams are responsible for evaluating raw materials, in-process materials, and associated documentation. By integrating advanced technologies into quality control procedures, manufacturers can improve accuracy, reduce waste, and enhance efficiency. This is where the distinction between traditional testing methods and innovative solutions becomes apparent.
Challenges in Traditional Non-Destructive Testing Methods
Limited Sensitivity
Traditional quality control methods, such as visual inspections and basic non-destructive techniques, can struggle to detect subtle defects or inconsistencies. Visual inspection is limited to only what the human eye sees, which is insufficient for pharmaceuticals that experience internal or non-visible defects. Although there are other more thorough NDT methods available, they also have their respective drawbacks.
Ultrasonic Testing (UT) detects discrepancies via sound. UT excels in some applications, but it is not as effective with pharmaceuticals, as it may struggle to penetrate through each layer of complex pharmaceutical formulations.
Dye penetrant inspection (DPI) is another popular NDT method which involves applying a dye to the surface of the product that seeps into any cracks. This method can work great for detecting surface defects, but as the complexity of most drugs lies in the internal structure, it is insufficient for pharmaceuticals.
Even traditional radiographic testing has its challenges. Although digital X-ray is a favorite for quality control in the pharmaceutical industry, traditional film-based X-ray systems struggled with producing precise imaging when differentiating between materials of similar density. For example, film-based X-rays can potentially struggle to distinguish between active pharmaceutical ingredients and excipients.
Time-Consuming Processes
Many traditional quality control methods require extensive procedures and multiple tests to comprehensively assess product quality. This can be especially problematic in an industry where time-to-market is critical. The lengthy duration of testing can delay production timelines and impact the availability of essential medications.
High Risk of False Negatives/Positives
Sometimes in the pharmaceutical quality control process, faults or discrepancies are not consistently detected. Oversights due to ineffective quality control procedures can pose a large spectrum of risks to patient safety.
The opposite effect can also occur, where instead of false negatives, false positives are produced. Flagging products as defective when they actually meet specifications can lead to unnecessary recalls, increased costs, and consumer distrust.
Difficulty in Adapting to Complex Formulations
Pharmaceutical products are advancing rapidly, and with that bringing increasingly complex formulations into the market. Current methods may not be well-equipped to handle innovative drug delivery systems, biopharmaceuticals, or personalized medicines, which demand more consistent and sophisticated testing methods.
Possibility of Batch Failures
With prolonged testing cycles and less effective detection mechanisms, the risk of batch failure rises. Batch failures can result in lost inventory, wasted resources, and regulatory scrutiny, further straining operations.
KA Imaging’s Dual-Energy Technology to Revolutionize Pharmaceutical NDT
KA Imaging’s response to these challenges comes in the form of their state-of-the-art dual-energy x-ray technology. This groundbreaking advancement offers a unique approach to non-destructive testing, setting a new standard for pharmaceutical quality control.
The dual-energy process works by using two different x-ray energy levels, allowing for the analysis of various materials within a single exposure. This capability enhances the identification of anomalies through meticulous material differentiation, while also reducing the need for re-testing or extensive manual inspections. The result is faster turnaround times, making it an invaluable asset for pharmaceutical companies striving for efficiency.
Reveal Technology & SpectralDR™
KA Imaging’s Reveal 35C™ X-ray Detector is equipped with their self-developed patented SpectralDR™ technology, allowing for detailed multi-layer imaging with a single exposure and no motion artifacts. Reveal 35C™ can capture high-resolution images that differentiate materials based on their atomic composition. This makes Reveal highly effective and efficient when screening complex materials, such as pharmaceuticals. While other X-rays will typically require multiple images, along with re-testing measures, Reveal can produce the same amount of visualization with only one exposure and no re-testing necessary.
BrillianSe™ X-Ray Detector
The BrillianSe™ X-Ray Detector is one of KA’s latest developments, and is especially effective for pharmaceutical applications thanks to its superior high-spatial resolution and phase contrast. The technology achieves this high spatial resolution using 8 μm pixels, which is also combined with high Detective Quantum Efficiency (DQE) for energies up to 110 keV. What makes BrillianSe™ a suitable solution for pharmaceutical applications is its phase contrast capability. This phase contrast allows for improved sensitivity while imaging low-density materials, which is a major obstacle found with other pharmaceutical quality control methods.
InCiTe™ 3D X-Ray Microscope
Low-density materials require advanced clarity and detailed detection for the most accurate screening results. This is where KA Imaging’s InCiTe™ 3D X-Ray Microscope comes in. Working in combination with the BrillianSe™ X-Ray Detector, InCiTe™ delivers a micro-CT solution that empowers users with more detailed and clear results. It can display intricately detailed images of biological structures, complex formulations, and other low-density specimens that other detectors fail to depict accurately and clearly. This has made InCiTe™ incredibly impactful with quality control for the pharmaceutical industry, as it is able to provide superior detail, leaving little room for misconceptions in the screening process.
