                          SERVICES (CONTINUED)

Sec. 211.72  Filters.

    Filters for liquid filtration used in the manufacture, processing, 
or packing of injectable drug products intended for human use shall not 
release fibers into such products. Fiber-releasing filters may not be 
used in the manufacture, processing, or packing of these injectable drug 
products unless it is not possible to manufacture such drug products 
without the use of such filters. If use of a fiber-releasing filter is 
necessary, an additional non-fiber-releasing filter of 0.22 micron 
maximum mean porosity (0.45 micron if the manufacturing conditions so 
dictate) shall subsequently be used to reduce the content of particles 
in the injectable drug product. Use of an asbestos-containing filter, 
with or without subsequent use of a specific non-fiber-releasing filter, 
is permissible

only upon submission of proof to the appropriate bureau of the Food and 
Drug Administration that use of a non-fiber-releasing filter will, or is 
likely to, compromise the safety or effectiveness of the injectable drug 
product.
