1. Purpose
This Standard Operating Procedure (SOP) outlines the storage requirements for Active Pharmaceutical Ingredients (APIs) under controlled conditions to ensure their stability, integrity, and compliance with Good Manufacturing Practices (GMP).
2. Scope
This SOP applies to all APIs stored in the warehouse that require controlled environmental conditions such as temperature, humidity, and light protection. It covers storage, monitoring, and documentation procedures.
3. Responsibilities
- Warehouse Personnel: Ensure APIs are stored under the specified controlled conditions and maintain accurate records of environmental monitoring.
- Quality Assurance (QA): Verify compliance with storage requirements, conduct periodic audits, and approve corrective actions if deviations occur.
- Warehouse Manager: Oversee storage operations, ensure proper functioning of monitoring equipment, and address non-conformities.
4. Accountability
The Warehouse Manager is accountable for ensuring APIs are stored under controlled conditions. The QA Manager is responsible for verifying compliance through regular inspections and audits.
5. Procedure
5.1 Storage Requirements for APIs
- Temperature Control:
- APIs must be stored within the temperature range specified by the manufacturer, typically between 15°C and 25°C unless otherwise stated.
- Use temperature-controlled rooms or units equipped with continuous monitoring devices.
- Document temperature readings in the Temperature Monitoring Log (Annexure-1).
- Humidity Control:
- Maintain relative humidity below 60% or as specified by the manufacturer.
- Dehumidifiers should be used in storage areas where required, and humidity levels must be continuously monitored.
- Document humidity readings in the Humidity Monitoring Log (Annexure-2).
- Light Protection:
- APIs sensitive to light should be stored in opaque containers or dark storage areas to prevent degradation.
- Ensure that storage areas are equipped with UV-protected lighting where necessary.
- Designated Storage Areas:
- APIs must be stored in designated, labeled storage areas with restricted access to authorized personnel only.
- Segregate APIs based on their storage requirements and ensure proper labeling (Annexure-3).
- Shelving and Racking:
- Use corrosion-resistant shelving and racking that allows for adequate airflow around the containers.
- Ensure APIs are stored off the floor and away from walls to prevent contamination.
- Environmental Monitoring:
- Continuously monitor temperature and humidity using calibrated devices with alarms for deviations.
- Perform manual checks daily and compare with automated system readings.
- Record all environmental data in the Environmental Monitoring Log (Annexure-4).
- Calibration of Monitoring Equipment:
- All monitoring equipment must be calibrated regularly according to the manufacturer’s recommendations.
- Document calibration activities in the Calibration Log (Annexure-5).
- Deviation Detection:
- If temperature or humidity deviates from the specified range, immediately investigate the cause and take corrective action.
- Document all deviations in the Deviation Log (Annexure-6).
- Corrective Actions:
- Move affected APIs to an alternative controlled environment until the issue is resolved.
- QA must evaluate the potential impact on product quality and decide on further actions.
- Document corrective actions in the Corrective Action Log (Annexure-7).
- Warehouse Inspections:
- Conduct regular inspections to verify compliance with storage conditions and procedures.
- Record findings in the Warehouse Inspection Log (Annexure-8).
- QA Compliance Audits:
- QA will conduct periodic audits to ensure all APIs are stored under the required controlled conditions.
- Document audit findings in the Compliance Audit Log (Annexure-9).
