Standard Operating Procedure for Validating Sigma Mixer / Kneader in Solid Dosage Form Production
Purpose
The purpose of this SOP is to define the validation process for the Sigma Mixer / Kneader used in the production of solid dosage forms, ensuring that the equipment consistently operates within predetermined specifications and quality standards.
Scope
This SOP applies to the Sigma Mixer / Kneader utilized in the Production/Granulation area for high-viscosity mass mixing. It covers all phases of validation including Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ).
Definitions
- Validation: The documented evidence that a system operates consistently within predetermined specifications.
- Criticality: Major – indicating a direct impact on product quality.
- URS: User Requirements Specification – defines the necessary requirements for the equipment.
Roles
- Validation Team: Responsible for the overall validation process.
- Quality Assurance: Ensures compliance with regulatory requirements.
- Production Personnel: Operate the equipment and provide feedback during validation.
Lifecycle Procedure
- Conduct User Requirements Specification (URS) assessment.
- Perform Design Qualification (DQ).
- Complete Installation Qualification (IQ).
- Execute Operational Qualification (OQ).
- Finalize Performance Qualification (PQ).
Good Documentation Practices (GDP) Controls
All validation documentation must adhere to Good Documentation Practices, ensuring clarity, accuracy, and traceability of data and results.
Acceptance Criteria Governance
Acceptance criteria will be established based on the User Requirements Specification (URS) and must be met during each qualification phase.
Calibration and Preventive Maintenance Governance
The Sigma Mixer / Kneader must undergo regular calibration and preventive maintenance as defined in the maintenance schedule to ensure optimal performance and compliance.
Change Control Triggers
Any changes to the equipment, process, or materials that may affect the validation status must be evaluated through the change control process.
Revalidation Triggers and Periodic Review
Revalidation is required every 24 months or upon significant changes to the equipment or process, as defined in the change control procedure.
