Approved by: [Approver’s Name]
Objective
The objective of this Operational Qualification (OQ) protocol is to verify that the High Shear Mixer/Homogenizer used in the production of Transdermal Patches operates within specified limits to ensure uniform drug distribution in the adhesive matrix.
Scope
This protocol applies to the High Shear Mixer/Homogenizer located in the Production area for the manufacturing of Transdermal Patches (TDS).
Responsibilities
- Validation Team: Responsible for conducting the OQ and documenting results.
- Quality Assurance: Responsible for reviewing and approving the protocol and results.
- Production Staff: Responsible for operating the equipment as per the validated procedures.
Prerequisites
All relevant documentation, including User Requirements Specification (URS) and equipment manuals, must be available prior to conducting the OQ.
Equipment Description
The High Shear Mixer/Homogenizer is designed to ensure uniform drug distribution in the adhesive matrix of Transdermal Patches. Key features include adjustable speed settings, temperature control, and viscosity measurement capabilities.
| Test ID | Procedure | Acceptance Criteria | Evidence |
|---|---|---|---|
| OQ-001 | Verify Speed Settings | Speed within specified range | Calibration logs |
| OQ-002 | Measure Shear Temperature | Temperature within specified limits | Temperature logs |
| OQ-003 | Check Viscosity | Viscosity within specified limits | Viscosity measurements |
| OQ-004 | Review PLC Logs | Logs indicate proper operation | PLC log reports |
Detailed Test Cases
Test Case OQ-001: Verify Speed Settings
Procedure: Set the mixer to the specified speed and verify using a calibrated tachometer. Document the readings.
Test Case OQ-002: Measure Shear Temperature
Procedure: Set the mixer to the operational temperature and verify using a calibrated thermometer. Document the readings.
Test Case OQ-003: Check Viscosity
Procedure: Prepare a sample and measure viscosity using a viscometer. Document the readings.
Test Case OQ-004: Review PLC Logs
Procedure: Access the PLC system and review logs for any errors or anomalies. Document findings.
Deviations
Any deviations from the acceptance criteria must be documented and investigated. A root cause analysis should be performed, and corrective actions must be implemented.
