Basic Princ iples of GMP
Remember to look atpunches and dies
Are there specifications for
these?
How are they cleaned,
stored, issued for use and
returned to storage?
Are they in a good
condition and checked atregular intervals?

Qualification and Validation
Definition
Qualification
Action of proving that any premises, systems and items of
equipment work correctly and actually lead to the expected
results
(Validation usually incorporates the concept of qualification)
A process of establishing confidence that the equipment is capable
of consistentlyoperating within established limits andtolerances. Studies therefore done prior to use

Qualification Vs. Validation
Qualification
- confirm compliance with specified requirements or criteria
(Do you have the right tool for the job?)
- Performed on one element or component of the process to be
validated
- Conduct tests to establish if the component of a process has the
attributes to produce a specified outcome.
Validation
- Proof. Document that the process will consistently produce a
predetermined outcome.

How may runs are to be performed during Operational
Qualification (OQ) testing?
Guidelines stress the importance of equipment qualificationsimulating actual production conditions, including 'worst case'
situations and that "tests and challenges should be repeated a
sufficient number of times to assure reliable and meaningful
results."
"three consecutive batches" is recommended for process
validation rather than for equipment qualification. No specific
number of "runs" for equipment qualification, but multiple tests to
simulate actual operating ranges and to establish consistency are
expected

For IQ document whether each equipment is installed correctly and
operates consistently according to established limits and
tolerances. OQ should also be performed for each different use of
the equipment or system to document the suitability for that use
Not be required for additional pieces of the same type/model of
equipment when used in the same process or for each piece of the
same type/model of equipment used in the same process, provided
installation qualification has been performed

More Examples
The following case illustrates the importance of performing adequate equipment qualification
on each piece of processing equipment
A pharmaceutical firm used two blenders to produce a tablet. Both blenders from same
equipment manufacturer, same model number and same design. Supplier told the drug
manufacturer that the units were "identical." though one was older. Manufacturer did not
include the older blender as part of its process validation.
Company marketed about 100 batches of tablets using the old blender. Retention samplesshowed some batches failed content uniformity
investigation showed out of specification batches were from one of the two "identical"
blendersthe old one. The older blender had a slightly smaller capacity and different
operational characteristics (RPMs) when run at the same settings as the newer blender.
Subsequently, the firm recalled its total production of the product it made using the olderblender. The firm decided to qualify the old blender using production size lots.

Qualification of Old Equipment
What about "old manufacturers" who have not performed DQ,
or IQ for existing, in-use systems and/or equipment?
It is not always possible to have all details for IQ or OQ for
established equipment. The manufacturer should howeverhave data that verifies the operating parameters and limits for
the critical variables of the equipment. In addition, calibration,
cleaning, preventative maintenance, operating procedures
and operator training procedures for the use of the equipment
should be documented and used as SOPs . PIC/S

Risk assessment of operations or
functions
Does function/operation directly impact product quality?
Does function/operation create (electronic) data which are the basis forGMP related activities?
Would malfunction impact directly on product quality
Does a measuring instrument control or measure quality critical processingsteps/parameters?
Does operation/installation cause contamination risk or product orenvironment
Are materials of construction in direct contact with the product?
If any question is answered Yes,the operation/function should be considered as
GMP relevant. During risk assessment, the probability of occurrence and
detectability should be considered and measures to reduce the risk identified.

Some Experiences
What if the results are not good?
Study report destroyed and manufacturer pretends it never
happened
So what should be done?
Document the study, but dont approve it
Identify and describe any corrective actions needed or any
noteworthy observations or deviations
Start another study using the findings and conclusions from the
failed study
