Documentation of Climatic Conditions for Stability Studies

Purpose

The purpose of this Standard Operating Procedure (SOP) is to establish the process for accurately recording and documenting the climatic conditions (temperature, humidity, etc.) during stability studies. This ensures that the environmental conditions are consistently monitored and reported, maintaining the integrity of the stability data.

Scope

This SOP applies to all stability studies conducted within the facility, covering all types of stability chambers and storage conditions used for drug products.

Responsibilities

• Stability Manager: Oversee the recording and documentation process of climatic conditions and ensure compliance with regulatory requirements.
• Stability Technicians: Perform daily monitoring, recording, and verification of climatic conditions.
• Maintenance Technicians: Ensure stability chambers are functioning correctly and calibrated as per the maintenance schedule.
• Quality Assurance (QA) Team: Review and approve recorded data and ensure proper documentation practices are followed.

Procedure

1. Monitoring and Recording:
   • Install calibrated temperature and humidity sensors in each stability chamber to continuously monitor climatic conditions.
   • Set up automated data logging systems

     to record climatic conditions at predetermined intervals (e.g., every 15 minutes).
   • Perform daily manual checks to verify the accuracy of automated recordings and log the readings in a designated logbook or electronic system.
   • Record any deviations from the specified conditions immediately and notify the Stability Manager.
2. Data Verification:
   • Stability Technicians should verify the recorded data daily for accuracy and completeness.
   • Cross-check manual recordings with automated data logs to ensure consistency.
   • Document any discrepancies and resolve them promptly with the assistance of Maintenance Technicians, if necessary.
3. Monthly Review:
   • Conduct a comprehensive review of recorded climatic data on a monthly basis.
   • Identify any trends or recurring deviations that might impact the stability study.
   • Prepare a summary report of the monthly review, highlighting any issues and corrective actions taken.
   • Submit the summary report to the Stability Manager and QA Team for review and approval.
4. Handling Deviations:
   • Document any deviation from specified climatic conditions, including date, time, duration, and extent of the deviation.
   • Investigate the cause of the deviation and take immediate corrective actions to restore the specified conditions.
   • Assess the impact of the deviation on the stability study and document the findings.
   • Report the deviation and the impact assessment to the Stability Manager and QA Team for review and approval.
5. Record Keeping:
   • Maintain all recorded climatic data, manual logs, deviation reports, and summary reports in a centralized location for easy access and review.
   • Ensure electronic data is backed up regularly and securely stored.
   • Archive records according to the facility’s document retention policy and regulatory requirements.
