21
22.
Calibration
Demonstrating that a measuring device
produces results within the specified limits of
those produced by a reference standard over
an appropriate range of measurements.
The devices are normally tagged and
supported by a maintenance procedures.
22
23. Site Acceptance Testing (SAT)
Inspection and dynamic testing of systems or
major system components to support the
qualification of an equipment system
conducted at a client site.
(Note : Not an obligation)
23
24.
Documented verification that all aspects of
a facility, utility or equipment that can affect
product quality operate as intended
throughout all anticipated ranges. It is the
process of testing to ensure that individual
components and systems operate as
specified, and how that information is
recorded.
24
25.
To establish through documented testing, that all
critical components and direct impact systems are
capable of operating within established limits and
tolerances.
To test parameters that regulate the process or
product quality. To verify the proper operation of
controllers, indicators, recorders, alarms and
interlocks, is performed and documented during the
operational qualification testing.

28
29.
Documented verification that all aspects of
a facility, utility or equipment that can
affect the product quality perform as
intended in meeting the predetermined
acceptance criteria.
29
30.
To integrate procedures, personnel, systems
and materials to verify that the utility /
environment / equipment / support systems
produces the required output. This output
may be a product contact utility, sterilization
condition or environment.
30
32. Process Validation
The documented verification providing a high
degree of assurance that a specific process will
consistently produce a product meeting its
predetermined specifications and quality
attributes.
The new guidelines aligns process validation
activities with a product life cycle concept.
32
34. Life Cycle of the product & the process
Stage 1 – Process Design
Stage 2 – Process qualification
Stage 3 - Continuous process verification
34
35.
It is the activity of defining the commercial manufacturing
process that will be reflected in planned master production
and control records.
The goal of this stage is to design a process suitable for
routine commercial manufacturing that can consistently
deliver a product that meets its quality attributes.
It is based on the knowledge gained through development &
scale-up activities.
35
36.
During this stage, the process design is evaluated to
determine if the process is capable of reproducible
commercial
manufacturing.
The
products
manufactured during this stage, if acceptable , can be
released for distribution.
Two Aspects
Design of facility and qualification of equipment and
utilities.
Process Performance Qualification ( PPQ).
36
37. Def.: “Releasing for distribution a lot of finished
product, manufactured following a qualification
protocol, that meets the standards established in
the protocol, but before the entire study has been
executed”.
Orphan Drugs
Specific drug for specific use
Shor t Shelf-life radio pharmaceuticals
37
38.
The goal of this stage is continual assurance that the
process remains in a state of control ( the validated state)
during commercial manufacture.
The cGMP requirements, specifically the collection &
evaluation of information & data about the performance
of the process will allow detection of undesired process
variability.
This stage is also applicable for legacy products.
38
39. Change Control
Formal evaluation of the potential impact of
planned modifications on the validated status
of a product, process or facility.

54. MAC = TD x BS x SF / LDD
MAC = Maximum Allowable Carryover
TD = Single Therapeutic Dose
BS = Batch size of next product to be
manufactured on the same equipment.
SF = Safety Factor
LDD = Largest Daily Dose of the next product
in the same equipment.
54
55. Ranitidine Tablets - Ibuprofen Tablets
TD = Single Therapeutic Dose = 150 mg Ranitidine-Tab
BS = Batch Size = 100 kg of Ibuprofen
SF
= Safety Factor = 1/1000
LDD
= Largest Daily Dose of the next product in the same
equipment = 200 mg X 5 tablets of Ibuprofen
MAC
= Max Allowable Carryover = 150 X 100 X 1000 x
1000 X 1/1000 X 1/1000
i.e 15000 mg in 100 kg Batch size
i.e 150 mg in 1 kg = 150 ppm
