What exactly are extractables and leachables in pharmaceutical testing?
Extractables are chemical compounds that can be released from packaging materials or medical devices under controlled laboratory conditions using aggressive solvents. Leachables are the actual compounds that migrate into drug products during normal storage and use conditions. Both must be carefully evaluated to ensure complete patient safety and product integrity.
Which international guidelines and standards govern E&L testing studies?
The primary guidelines include ISO 10993-18 for medical device materials, USP <1663> and <1664> for pharmaceutical packaging, and ICH Q3D for elemental impurities. These comprehensive standards provide detailed methodologies for E&L characterization, toxicological risk assessment, and establishing acceptable exposure limits for patient safety.
What advanced analytical techniques are used for accurate E&L analysis?
We employ a comprehensive suite of analytical methods including GC-MS (Gas Chromatography-Mass Spectrometry), LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry), ICP-MS (Inductively Coupled Plasma-Mass Spectrometry), and FTIR (Fourier Transform Infrared Spectroscopy), selecting the most appropriate techniques based on the expected chemical nature of extractables and leachables in your specific test matrix.
Do you provide comprehensive toxicological evaluation services?
Yes, we offer complete toxicological risk assessment (TRA) services for all identified leachables. This includes determining potential patient health risks, comparing detected levels against established safety thresholds, and providing expert recommendations on whether concentrations exceed permitted regulatory limits for your specific application.
Can you conduct realistic simulated-use testing studies?
Absolutely. We design customized simulated-use protocols that accurately reflect real-world conditions, including appropriate solvent systems, realistic temperature ranges, and proper time durations based on your intended drug product usage patterns. This ensures our leachables assessment truly represents what patients might be exposed to during actual product use.
What comprehensive services are included in E&L Testing packages?
Our complete E&L testing services include developing customized study protocols tailored to your specific products, comprehensive extractables profiling using advanced analytical methods, detailed leachables testing under realistic simulated-use conditions, and professional toxicological risk assessments when required for complete safety evaluation.
Which industries and companies benefit most from professional E&L Testing services?
Pharmaceutical manufacturers, medical device companies, biopharmaceutical organizations, and injectable drug product developers all benefit significantly from our specialized E&L testing solutions. Any company developing packaging systems, drug delivery devices, or combination products requires these services for regulatory compliance and patient safety assurance.
