1. Purpose

To provide a standardized approach for troubleshooting and resolving capping and lamination issues during the tablet compression process, ensuring that all tablets meet the required quality specifications.

2. Scope

This SOP applies to the troubleshooting of capping and lamination issues during tablet compression, focusing on identifying causes and corrective actions to improve tablet integrity.

3. Responsibilities

4. Accountability

The Production Manager is accountable for the resolution of capping and lamination issues and ensuring that the tablet compression process runs smoothly. The QA Manager ensures compliance with this SOP and regulatory standards.

5. Procedure

5.1 Identifying Capping and Lamination Issues

  1. During the tablet compression process, observe any irregularities in tablet formation, particularly cracking, separation of tablet layers, or incomplete tablet formation.
  2. Check for capping, which is when the upper surface of the tablet splits or separates, often due to high compression forces or improper granule flow.
  3. Examine for lamination, where multiple layers of the tablet form due to excess lubrication, insufficient binder, or improper tablet press settings.
  4. Note the frequency of these issues to identify whether they are isolated incidents or recurring problems that require immediate attention.

5.2 Potential Causes and Troubleshooting for Capping

  1. Excessive Compression Force: If tablets are experiencing capping, check the compression force. If too high, decrease the force and test again. Document any changes.
  2. Poor Granule Flow: If granules are not flowing properly, ensure they are adequately lubricated. Adjust the lubrication process to improve granule flow.
  3. Moisture Content Issues: Low moisture content in the granules can result in brittle tablets. Ensure that the moisture content is within acceptable levels before compression.
  4. Inadequate Pre-Compression: Ensure the tablet press is set to provide sufficient pre-compression to improve tablet bonding before main compression.
  5. Adjust machine parameters and observe changes. Continue troubleshooting until tablet quality improves.

5.3 Potential Causes and Troubleshooting for Lamination

  1. Excess Lubricant: Excess lubricant can cause lamination by preventing proper bonding of tablet layers. Reduce the amount of lubricant used in the granulation process.
  2. Improper Binder: Check that the binder is correctly formulated and mixed. Insufficient binder can lead to weak tablets prone to lamination.
  3. Granule Size Issues: Granules that are too fine or too large can cause uneven compression. Ensure the granule size is consistent and within specification.
  4. Machine Settings: Adjust the speed and pressure of the tablet press. Higher speeds can lead to increased lamination issues, so reduce the speed and pressure to see if the problem improves.
  5. Make adjustments and continue testing until the issue is resolved. Monitor tablet quality closely after each change.

5.4 In-Process Quality Control

  1. Perform visual inspections of tablets throughout the compression process. Use a tablet hardness tester and visual inspection to detect any capping or lamination issues early on.
  2. Perform regular checks for tablet weight, thickness, and appearance. Record results in the batch record (Annexure-1).
  3. If a pattern of capping or lamination issues is observed, escalate to the QA team for a thorough investigation and to determine further corrective actions.

5.5 Machine Parameter Adjustments

  1. If troubleshooting indicates the need for adjustments, reconfigure the tablet press settings. This may include altering compression force, tablet speed, or die settings.
  2. After adjustments, run test batches to monitor if the capping and lamination issues have been resolved.
  3. Document all adjustments made, including parameters changed and the outcome of the tests in the batch record.

5.6 Corrective Action and Documentation

  1. If corrective actions are implemented, record the issue, cause, corrective action, and resolution in the batch record (Annexure-2).
  2. Ensure all involved personnel sign off on the corrective actions taken, and provide detailed explanations of any deviations or unexpected results.
  3. Review process parameters and tablet quality data to confirm that the capping and lamination issues have been resolved. Approve any changes in the process if necessary.

5.7 Documentation and Record-Keeping

  1. Ensure that all troubleshooting activities, including observations, machine adjustments, and corrective actions, are documented in the batch record.
  2. Sign and review all records to confirm that all issues have been addressed, and document final tablet quality in the quality control log (Annexure-3).
  3. Maintain all records for future reference and in compliance with GMP regulations.
