Standard Operating Procedure for Jet Mill/Spiral Mill Equipment Validation

Purpose: This SOP outlines the validation process for the Jet Mill and Spiral Mill used in the micronization of Active Pharmaceutical Ingredients (APIs) for inhalation, ensuring compliance with regulatory standards.

Scope: This procedure applies to the validation of Jet Mill and Spiral Mill equipment used in the R&D and production of inhaled NDDS powders within the pharmaceutical industry.

Definitions:

• API: Active Pharmaceutical Ingredient.
• NDDS: Novel Drug Delivery Systems.
• DQ: Design Qualification.
• IQ: Installation Qualification.
• OQ: Operational Qualification.
• PQ: Performance Qualification.
• CSV: Computerized System Validation.

Roles:

• Validation Team: Responsible for developing and executing validation protocols.
• Quality Assurance: Ensures compliance with regulatory standards and reviews validation documentation.
• Engineering: Provides technical support and ensures equipment is maintained and calibrated.

Lifecycle Procedure:

1. Conduct Design Qualification (DQ) to verify that the design meets user requirements.
2. Perform Installation Qualification (IQ) to ensure the equipment is installed correctly.
3. Execute Operational Qualification (OQ) to confirm the equipment operates within specified limits.
4. Complete Performance Qualification (PQ) to demonstrate that the equipment performs as intended under actual production conditions.

GDP Controls: Good Documentation Practices (GDP) must be followed throughout the validation process to ensure all records are complete, accurate, and traceable.

Acceptance Criteria Governance: Acceptance criteria will be established based on User Requirement Specifications (URS) and must comply with Annex 11 and Annex 15 of the EU GMP guidelines.

Calibration/PM Governance: Equipment must be calibrated and maintained according to a predetermined schedule, with records maintained for all calibration and preventive maintenance activities.

Change Control Triggers: Any changes to the equipment, processes, or operating procedures that may affect the validated state must initiate a change control process.

Revalidation Triggers and Periodic Review: Revalidation is required every 12 months or when significant changes occur. A periodic review of the validation status will be conducted annually to ensure continued compliance.
