manufacturing areas shall be carried out during operations. Results of
such count shall be checked against established in-house standards and
record maintained.
Access to manufacturing areas shall be restricted to minimum number
of authorised personnel. Special procedure to be followed for entering
and leaving the manufacturing areas shall be written down and
displayed.
For the manufacturing of Ayurvedic, Siddha and Unani drug that can be
sterilised in their final containers, the design of the areas shall
preclude the possibility of the products intended for sterilisation
being mixed with or taken to be products already sterilised. In case
of terminally sterilised products, the design of the areas shall
preclude the possibility of mix up between non-sterile and sterile
products.
(B) Precautions against contamination and mix:
- Carrying out manufacturing operations in a separate block of
adequately isolated building or operating in an isolated enclosure
within the building.
- Using appropriate pressure differential in the process area.
- Providing a suitable exhaust system.
- Designing laminar flow sterile air systems for sterile products.
- The germicidal efficiency of UV lamps shall be checked and
recorded indicating the burning hours or checked using intensity.
- Individual containers of liquids, and opthalmic solutions shall
be examined against black-white background fitted with diffused
light after filling to ensure freedom from contamination with
foreign suspended matter.
- Expert technical staff approved by the Licensing Authority shall
check and compare actual yield against theoretical yield before
final distribution of the batch.
All process controls as required under master formula including room
temperature relative humidity, volume filled, leakage and clarity
shall be checked and recorded.
