ICH Q3B(R2) Stability Testing of Impurities in Drug Products: Eurolabs Laboratory Testing Service

ICH Q3B(R2) is a regulatory guideline that governs the stability testing of impurities in drug products. This guideline is published by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), which is an international organization that aims to harmonize regulatory requirements for pharmaceuticals worldwide.

The ICH Q3B(R2) guideline provides detailed recommendations on the testing and evaluation of residual solvents, impurities, and degradation products in drug substances and products. The guideline emphasizes the importance of stability testing in ensuring the safety and efficacy of pharmaceutical products.

The relevant standards that govern ICH Q3B(R2) Stability Testing of Impurities in Drug Products testing include:

  • ISO 14687:2010 - Water for nuclear-purpose use (does not directly apply to drug product testing, but provides a framework for understanding impurity testing)

  • ASTM E1615-19 - Standard Practice for Conducting Accelerated Stability Tests on Pharmaceuticals

  • EN ISO/IEC 17025:2018 - General requirements for the competence of testing and calibration laboratories

  • TSE (Turkish Standards Institution) - Turkish standards equivalent to international standards

    • The International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), European Committee for Standardization (CEN), and Turkish Standards Institution (TSE) are standard development organizations that publish and maintain standards related to ICH Q3B(R2).

    Standards evolve and get updated to reflect new scientific understanding, technological advancements, and changing regulatory requirements. For example, the ASTM E1615-19 standard was revised in 2019 to incorporate new methods for accelerated stability testing.
