    3. Dose uniformity calculation: The percentage deviation of individual units from the mean is calculated.

    4. Uniformity of dosage units determination: The percentage of non-uniform units per batch is determined.

    5. Related impurities analysis: Specified impurities are analyzed to ensure compliance with maximum allowable limits.

    Interlaboratory Comparison

    Interlaboratory comparison (ILC) is a process where multiple laboratories test the same sample using Ph. Eur. 2.9.40: Uniformity of Dosage Units and Related Impurities testing. This helps evaluate laboratory performance, ensuring consistency and reliability in results.

    The test report provides detailed information on the test results, including:

  • Dose uniformity: Average weight or volume percentage deviation

  • Uniformity of dosage units: Percentage of non-uniform units per batch

  • Related impurities: Maximum allowable limits for specified impurities

    • Upon successful completion of Ph. Eur. 2.9.40: Uniformity of Dosage Units and Related Impurities testing, a certificate is issued to the manufacturer or supplier.

    Ph. Eur. 2.9.40: Uniformity of Dosage Units and Related Impurities testing requires validation of the test method:

  • Specificity: The ability of the test to detect specified impurities

  • Sensitivity: The ability of the test to detect non-uniform units or impurities at their maximum allowable limits

  • Accuracy: The closeness of the test results to the true values

    • Validation is essential to ensure that the test method is reliable and produces consistent results.

    Ph. Eur. 2.9.40: Uniformity of Dosage Units and Related Impurities testing is a critical laboratory testing service ensuring compliance with European Pharmacopoeia standards. The test requires validation, interlaboratory comparison, and certification to guarantee the quality and safety of pharmaceutical products.
