1. Purpose

This SOP outlines the procedure for implementing risk-based monitoring during tablet manufacturing processes. The goal is to focus resources on critical process parameters (CPPs) and critical quality attributes (CQAs) to mitigate risks that could impact product quality, compliance, and patient safety.

2. Scope

This SOP applies to all tablet manufacturing processes where risk-based monitoring is required. It covers identifying critical process parameters, assessing associated risks, and setting up monitoring strategies to ensure that process deviations are promptly detected and controlled.

3. Responsibilities

4. Accountability

The QA Manager is accountable for ensuring that risk-based monitoring is effectively implemented throughout the manufacturing process. The Production and QC teams are responsible for executing monitoring activities, while the Risk Management team is responsible for risk assessments and mitigation.

5. Procedure

5.1 Identifying Critical Process Parameters (CPPs)

  1. Collaborate with the production and QC teams to identify the critical process parameters (CPPs) for each tablet manufacturing process (e.g., temperature, pressure, flow rate, etc.).
  2. Evaluate the impact of each CPP on the final product quality to determine which parameters should be monitored more closely.
  3. Document all identified CPPs, including justification for their criticality (Annexure-1).

5.2 Risk Assessment

  1. Conduct a risk assessment to determine the likelihood and severity of risks associated with the identified CPPs and CQAs.
  2. Utilize a risk matrix or other tools to categorize the risk level (e.g., high, medium, low) for each CPP (Annexure-2).
  3. Prioritize monitoring efforts on high-risk areas to ensure that resources are allocated efficiently.
  4. Document the risk assessment results and mitigation strategies (Annexure-3).

5.3 Monitoring Strategy Development

  1. Develop a monitoring plan based on the identified risks and critical parameters. The plan should include:
    • Frequency of monitoring
    • Methods of monitoring (manual or automated)
    • Accepted control limits for each CPP and CQA
    • Corrective actions for deviations
  2. Ensure that monitoring systems are in place to collect real-time data on the identified parameters (Annexure-4).
  3. Communicate the monitoring plan to all relevant personnel involved in the production process.

5.4 Monitoring During Production

  1. Implement the monitoring plan during tablet production, ensuring that critical parameters are regularly checked and recorded.
  2. Monitor key process variables, such as mixing times, granulation temperature, tablet compression force, and coating thickness.
  3. Immediately report any deviations outside of predefined acceptable limits to the QA Manager and the production team for corrective action.
  4. Record all monitoring data for traceability and future audits (Annexure-5).

5.5 Corrective and Preventive Actions

  1. If deviations are detected during the manufacturing process, initiate corrective actions to return the process to within acceptable limits.
  2. Investigate the root cause of the deviation and implement preventive measures to avoid recurrence.
  3. Document all corrective actions, preventive measures, and follow-up results (Annexure-6).

5.6 Documentation and Record Keeping

  1. Ensure all risk assessments, monitoring plans, monitoring data, corrective actions, and preventive actions are fully documented and stored securely.
  2. Retain all records for a minimum of 5 years or as required by regulatory standards (Annexure-7).
