Procedures for Addressing Deviations in Moisture Content Levels

1) Purpose

The purpose of this SOP is to outline the actions to be taken if the moisture content of capsules deviates from the acceptable limits, ensuring product quality and compliance.

2) Scope

This SOP applies to all capsules manufactured within the pharmaceutical facility, particularly those containing hygroscopic formulations.

3) Responsibilities

The Quality Control (QC) department is responsible for detecting deviations in moisture content and initiating corrective actions. The Production department is responsible for implementing the corrective actions.

4) Procedure

1. Detection of Deviations:
   1. Review the moisture content test results against the established acceptance criteria.
   2. If any result falls outside the acceptable range, document the deviation in the moisture content logbook.
2. Initial Investigation:
   1. Notify the QC manager immediately upon detection of a deviation.
   2. Conduct a preliminary investigation to identify any obvious errors in the testing process, such as instrument malfunction or operator error.
3. Root Cause Analysis:
   1. If no obvious error is found, perform a detailed root cause analysis to determine the underlying cause of the deviation.
   2. Examine factors such as raw material quality, manufacturing process parameters, and environmental conditions.
4. Corrective Actions:
   1. Based on the root cause analysis, develop and implement corrective actions to address the issue.
   2. Examples of corrective actions include adjusting manufacturing parameters, retraining operators, and improving raw material inspection procedures.
5. Retesting:
   1. After implementing corrective actions, retest the affected batch of capsules to confirm that the moisture content meets the specified criteria.
   2. Document the retest results and compare them to the original deviation results.
6. Documentation and Reporting:
   1. Document all findings, corrective actions, and retest results in the moisture content logbook and the deviation report.
   2. Submit a final report summarizing the investigation and corrective actions to the QC manager for approval.
7. Preventive Actions:
   1. Review the deviation incident and identify preventive actions to avoid recurrence.
   2. Update SOPs, training materials, and process controls as necessary to incorporate the preventive actions.
