Guidance on the Manufacture of Sterile Pharmaceutical Products by Aseptic Processing
- 37 -
4. Flow lines for sterile pharmaceutical products, sterile raw materials, and other sterile materials
should beadequately designed by taking into account personnel movement and airflow
patterns.
5. Personnel movement and intervention into sterile pharmaceutical products should be designed
to be minimum. In addition, operation, maintenance, repair, and adjustment of equipment
should preferably be performed from outside the critical area, whenever feasible.
6. Generation of turbulence and particles in critical areas should be controlled to a minimum.
The flow of clean air from supply vent to return or exhaust vent should be optimally designed
in direct and indirect support areas.
7. Equipment should be laid out so as to minimize the physical burden on operators.
8. Requirement specifications (user requirements specifications, URS) for equipment and utilities
should be defined in writing with regard to required quality levels, facility capacity for
amounts of use during manufacture, applicable regulatory requirements (e.g. laws, regulations,
guidelines), quality of component materials, and performance, etc., and DQ should be
conducted in accordance with the URS.
9. The duration of exposure of sterile pharmaceutical products, surface of equipment that may
contact with sterile pharmaceutical products, and containers uncapped, should be kept as short
as possible. 10. IQ should verify that the equipment and utilities have been installed as
directed in relevant design specification in accordance with written procedures.
11. OQ should verify that equipment and utilities have a capacity of performance as required by
their specifications. If the equipment and utilities are to be operated or used in APAs, it should
be verified that the required cleanliness in the APAs is maintained throughout operation or use.
12. All processes conducted in the APA that may influence the sterility of pharmaceutical
products should be scientifically evaluated and appropriately validated.
13. Operational procedures for all key equipment and control parameters, and theire acceptable
limits should be described in relevant SOPs in an appropriate manner.
14. Validation of the processes utilizing cleaning, sterilizing, incubating/fermenting, filtering,
filling, capping, freeze-drying, and sealing equipment should be conducted to assess the
sterility assurance level of pharmaceutical products in each of these processes. Sterility
assurance levels may be validated together for multiple processes using different equipment if
the processes are continuous.
15. The sterility of equipment surfaces that may come into direct contact with sterile
pharmaceutical products should be validated.
16. OQ studies should be conducted for utilities including CIP/SIP systems and equipment that
