Validating a Heat-Sterilizing Tunnel
|
The validation department writes and executes validation
protocols to demonstrate that equipment, activities, and processes
consistently produce products or results that meet approved
specifications. Validation is conducted on manufacturing
processes, aseptic operations, equipment cleaning procedures,
equipment, and computerized systems. The validation group also
evaluates proposed changes to determine if additional studies need
to be done. Validation is also conducted on analytical methods
used in laboratories; sometimes a lab methods validation group is
responsible for doing these.
Example of a GMP expectation that applies to Validation
Documented evidence is available which shows that
all parts of the manufacturing and control process will produce a drug
product which consistently complies with its specifications.
Example of GMP requirements specific to this GMP expectation
U.S.
-
There shall be written procedures for
production and process control designed to assure that the
drug products have the identity, strength, quality, and purity
they purport or are represented to possess. [211.100(a)]
-
Such control procedures shall be established
to monitor the output and to validate the performance of those
manufacturing processes that may be responsible for causing
variability in the characteristics of in-process material and
the drug product. [211.110(a)]
Canada
-
Every fabricator and packager/labeller and
subject to subsections (3) and (4), every distributor referred
to in section C.01A.003(b) and importer of a drug shall
maintain a system designed to ensure that any lot or batch of
the drug fabricated and packaged/labelled on premises other
than their own is fabricated and packaged/labelled in
accordance with the requirements of this Division. [C.02.012 #2]
European Union
-
Validation studies should reinforce Good
Manufacturing Practice and be conducted in accordance with
defined procedures. Results and conclusions should be
recorded. [EU #5.21]
-
When a new manufacturing formula or method
of preparation is adopted, steps should be taken to
demonstrate its suitability for routine processing. The
defined process, using the materials and equipment specified,
shown to yield a product consistently of the required quality.
[EU #5.22]
