Leachables and Extractables Testing
The testing of leachables and extractables is a critical process in pharmaceutical development. This procedure ensures that any substance released from packaging materials, excipients, or other formulation ingredients during the production or use phase does not pose a risk to product quality or patient safety.
Leachables are substances that may dissolve into a drug product or its container system over time. Extractables, on the other hand, refer to compounds that can be transferred from packaging materials to the drug substance under specific conditions during processing and storage. Together, these two terms encompass all potential contaminants introduced through contact with the drug.
The testing of leachables and extractables is governed by several international standards including ISO 10993-18 for medical devices and pharmaceuticals, ASTM E2347 for plastic containers, and IEC 60601-2-13 for electrical/electronic medical equipment. Compliance with these standards ensures that the testing process adheres to recognized best practices.
The scope of leachables and extractables testing includes a wide range of materials such as packaging components (plastics, metals), excipients used in formulations (microcrystalline cellulose, lactose monohydrate), and even the manufacturing equipment itself. The goal is to identify any potential contaminants that could affect drug stability or integrity.
Specimen preparation for this testing involves selecting appropriate samples based on their expected contribution to leachables and extractables. This might include cutting coupons from packaging materials, dissolving excipients in solvents like methanol, or simulating the manufacturing process with equipment. Once prepared, these samples undergo rigorous analysis using advanced analytical techniques.
Instrumentation used for this purpose can vary widely depending on the type of material being tested and its potential contribution to leachables/extractables. Commonly employed methods include gas chromatography (GC), liquid chromatography (LC), mass spectrometry (MS), inductively coupled plasma optical emission spectroscopy (ICP-OES), and atomic absorption spectroscopy (AAS). Each method has unique advantages suited for different types of substances.
After analysis, results are interpreted according to predefined acceptance criteria set forth by regulatory bodies like the FDA or EMA. These criteria establish thresholds above which certain levels of leachables or extractables would be considered problematic. Compliance with these standards ensures that only safe products reach the market.
In summary, leachables and extractables testing plays a crucial role in ensuring drug safety and efficacy by identifying any potential contaminants introduced through contact between packaging materials/ingredients and the active pharmaceutical ingredient (API). By following established protocols outlined in international guidelines such as ISO 10993-18 or ASTM E2347, laboratories can provide reliable data that supports informed decision-making throughout the drug development lifecycle.
