What should gmp in pharmaceutical industry pay attention to when conducting FAT inspections?
1. Equipment Basic Function Verification
Confirm that filling volume accuracy (±1%) meets process requirements; test filling consistency across different specifications (e.g., 0.5mL, 1mL).
Verify whether the maximum and minimum filling speeds meet standards; assess the impact of speed variation on accuracy.
Sealing Test
Check the seal integrity of pre-filled syringes after filling (e.g., seal between plunger and needle) to avoid leakage or contamination risks.
Aseptic Barrier System
Confirm the integrity of the isolator or RABS (Restricted Access Barrier System) (e.g., pressure differential, particle monitoring).
2. GMP Compliance Check,GMP in pharmaceutical industry
Materials and Surface Finish
Product-contact parts (e.g., filling needles, liquid transfer tubing) must be made of 316L stainless steel and medical-grade silicone, complying with aseptic requirements.
Cleaning and Sterilization Validation
Check CIP (Clean-in-Place) and SIP (Sterilize-in-Place) functions to ensure no dead legs, and that residue and bioburden limits comply with standards.
Data Integrity
Confirm that the control system (e.g., PLC) supports traceability, is non-alterable, and has a fully functional audit trail.
3. Automation and Control System
Human-Machine Interface (HMI)
Verify that the operational interface is user-friendly and that parameter setting, alarm logging, and fault diagnosis functions are adequate.
Sensors and Feedback
Check the sensitivity and reliability of key sensors (e.g., liquid level detection, stop-on-no-container).
Batch Record and Electronic Signature
Ensure automatic generation of batch reports and support for electronic signatures.
4. Safety and Risk Control
Mechanical Safety
Verify emergency stop buttons, protective door interlocks, pinch-point protection design, etc.
Biosafety
High-risk operation areas (e.g., filling needle zone) must have biosafety protection (e.g., laminar airflow protection).
Deviation Handling
Simulate common faults (e.g., filling volume deviation, missing stopper) and confirm the effectiveness of alarms and automatic rejection mechanisms.
5. Documentation and Supplier Support
Technical Documentation Review
Check whether equipment manuals, DQ/IQ/OQ/PQ templates, spare parts lists, material certificates, etc., are complete.
Supplier Services
Confirm that the supplier provides training and maintenance support, and clarify response times.
6. Environment and Utility Compatibility
Utility Interfaces
Verify the compatibility of the equipment with site utilities such as water, electricity, compressed air, and nitrogen (e.g., pressure, purity requirements).
Environmental Monitoring
Test the impact of equipment operation on the cleanroom environment (e.g., particle count).
7. Simulation Production Test
Worst-Case Challenge
Test equipment stability under extreme parameters (e.g., minimum speed, maximum viscosity liquid).
Continuous Operation Test
Conduct a 72-hour continuous operation test to evaluate equipment reliability and failure rate.
8. Regulation and Standard Compliance
Confirm equipment compliance with the following standards:
GMP Requirements,GMP in pharmaceutical industry
ISO 9001
Key Considerations
User Involvement: Production, Quality, and Engineering departments must participate throughout the FAT to ensure all requirements are addressed.
Risk Priority: Prioritize testing of high-risk items (e.g., sterility assurance, data integrity).
Record Retention: All test data and deviation reports must be archived and serve as the basis for subsequent SAT (Site Acceptance Testing).
