Sterilisation is crucial in pharmaceutical manufacturing and research to attain desired levels of bioburden reduction, ensuring products are safe, effective, and contamination-free. This protects patient health, maintains the integrity of medicinal products and ensures accurate research outcomes.
Ensuring robust practices for bio-decontamination verification – often a crucial step in the wider sterilisation process – ensures a reduction in risk of product failure, infection and compromised research validity significantly increases, making it a vital part of pharmaceutical operations.
Bio-decontamination supports compliance with regulatory standards like GMP and prevents cross-contamination during production or experimentation.
Protak Scientific produces Enzyme Indicators, a diagnostic tool used for the effective monitoring of bio-decontamination efficacy. The indicators may be used to show equivalency with Biological Indicators, to test bio-decontamination validation success or failure within 60 seconds. This allows many large-scale pharmaceutical manufacturers to quickly change and test the sanitisation system and drastically optimise the validation process via reduced downtime and increased cycle efficiency.
| Biological Indicators | Enzyme Indicators | |
| Time for results | > 7 days | 60 seconds |
| Data available | Binary | Quantitive values |
| Variation | -50-300% | < 15% |
| Source | Bacterial Spores | Enzymes |
| Behavior | Viable | Non-viable |
Enzyme Indicators offer a range of advantages over traditional Biological Indicators for effective bio-decontamination validation. One of the major benefits is Enzyme Indicators’ ability to provide clear, quantifiable results in seconds rather than days. This means users can have full confidence in the effectiveness of their bio-decontamination and sterilisation processes, which in turn leads to improved efficiency and reduced costs for these critical activities.
Traditional Biological Indicators require a seven-day or more incubation period before they can provide a result as to whether a gaseous bio-decontamination process has failed. By contrast, Enzyme Indicators give answers in just 60 seconds. This helps to achieve faster quantitative results with a higher degree of accuracy and drives down costs through reductions in overheads, all while continuing to safeguard product integrity.
Because Enzyme Indicators offer detailed, quantifiable data as opposed to the binary pass/fail information Biological Indicators deliver, this allows users to create data on their activities using the Athena software. In turn, this data can be used to identify areas for bio-decontamination cycle improvement.
Enzyme Indicators can improve validation cycles, streamline bio-decontamination processes and facilitate rapid problem-solving by delivering quantitative, real-time data on microbial inactivation.
Immediate assessment of bio-decontamination efficacy enables prompt decision-making and reduces downtime. This rapid feedback is crucial for optimising bio-decontamination cycles, as it helps to identify areas where the distribution may be inadequate or where dwell times need adjustment.
The precise data obtained from Enzyme Indicators can also support product disposition, quality assurance risk assessments, root-cause analysis and corrective actions, contributing to continuous improvement and compliance in environments where sterility is critical.
