Standard Operating Procedure for the Validation of Solvent Addition/Metering Pump
Purpose: This SOP outlines the validation process for the Solvent Addition/Metering Pump utilized in the controlled addition of solvents and active pharmaceutical ingredients (APIs) in the development and production of polymeric nanoparticles.
Scope: This procedure applies to all personnel involved in the validation, operation, and maintenance of the Solvent Addition/Metering Pump in the R&D and production areas, specifically for the formulation of NDDS utilizing PLGA and similar polymers.
Definitions:
- Validation: The process of demonstrating that a procedure, process, or activity will consistently lead to the expected results.
- Criticality: The significance of the equipment’s function in relation to product quality and safety.
- CSV: Computerized System Validation, ensuring that computerized systems operate as intended and comply with regulatory requirements.
Roles:
- Validation Team: Responsible for planning, executing, and documenting the validation activities.
- Quality Assurance: Ensures compliance with regulatory standards and reviews validation documentation.
- Operations Personnel: Operate the equipment and follow the validated procedures.
Lifecycle Procedure:
- Design Qualification (DQ): Verify that the design of the Solvent Addition/Metering Pump meets user requirements.
- Installation Qualification (IQ): Confirm that the equipment is installed according to specifications.
- Operational Qualification (OQ): Assess the equipment’s performance under normal operating conditions.
- Performance Qualification (PQ): Validate the equipment’s ability to consistently produce the desired results in actual production conditions.
GDP Controls: Good Documentation Practices must be adhered to throughout the validation process, ensuring that all documentation is accurate, complete, and readily accessible.
Acceptance Criteria Governance: Acceptance criteria must align with the User Requirement Specification (URS) and Annex 11 of the relevant regulatory guidelines.
Calibration/PM Governance: The Solvent Addition/Metering Pump must undergo calibration and preventive maintenance as per the manufacturer’s specifications and internal quality standards.
Change Control Triggers: Any changes to the equipment, process, or associated software must undergo a formal change control process to assess the impact on validation status.
Revalidation Triggers and Periodic Review: Revalidation is required annually or whenever there is a significant change in the process, equipment, or operating conditions. A periodic review of the validation status will be conducted to ensure ongoing compliance.
