Document Control Number: DQ-TDS-001
Version: 1.0
Effective Date: 2023-10-01
Reviewed By: [Name]
Approval Date: [Date]
Objective
The objective of this Design Qualification (DQ) protocol is to verify that the Patch Coating Machine meets the specified requirements for the production of transdermal patches, ensuring compliance with regulatory standards and company policies.
Scope
This DQ protocol applies to the Patch Coating Machine (Knife-over-roll / Slot Die) used in the production area for coating the drug adhesive layer onto the backing film for transdermal patches.
Responsibilities
- Validation Team: Responsible for executing the DQ protocol and documenting results.
- Quality Assurance: Responsible for reviewing and approving the DQ protocol.
- Production Team: Responsible for operating the Patch Coating Machine during the validation process.
Prerequisites
- Completion of User Requirement Specification (URS).
- Installation Qualification (IQ) completed and documented.
- Standard Operating Procedures (SOPs) for operation of the Patch Coating Machine available.
Equipment Description
The Patch Coating Machine (Knife-over-roll / Slot Die) is designed to apply a precise layer of drug adhesive onto the backing film, ensuring uniformity and adherence to specified parameters. Key features include adjustable coating thickness, speed control, temperature regulation, and tension monitoring.
Test Plan
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| TDS-DQ-01 | Verify coating thickness | Within specified range as per URS | Measurement logs |
| TDS-DQ-02 | Check coating speed | Within specified limits | PLC logs |
| TDS-DQ-03 | Monitor temperature during operation | Within specified temperature range | Temperature logs |
| TDS-DQ-04 | Measure tension during coating | Within specified tension limits | Tension logs |
Detailed Test Cases
Test Case: Coating Thickness Verification
- Procedure: Measure the thickness of the coated layer at multiple points on the backing film.
- Acceptance Criteria: Coating thickness must be within the range specified in the URS.
- Evidence: Document all measurements in the validation log.
Test Case: Coating Speed Assessment
- Procedure: Run the machine at various speeds and record the output.
- Acceptance Criteria: Coating speed must fall within the defined limits.
- Evidence: PLC logs will be reviewed and documented.
Test Case: Temperature Monitoring
- Procedure: Monitor the temperature of the coating machine during operation.
- Acceptance Criteria: Temperature must remain within the specified range.
- Evidence: Temperature logs will be maintained and reviewed.
Test Case: Tension Measurement
- Procedure: Measure the tension on the backing film during the coating process.
- Acceptance Criteria: Tension must be within the specified limits.
- Evidence: Tension logs will be recorded.
Deviations
Any deviations from the acceptance criteria must be documented and assessed for impact on product quality. A corrective action plan will be required for any critical deviations.
