stage through commercial production, which
establishes scientific evidence that process is
capable of consistently delivering quality
product.”
(FDA Guidelines, 2011)

5. “Action of proving, in accordance with the
principles of Good Manufacturing Practice
(GMP), that any procedure, process,
equipment, material, activity or system
actually leads to expected results.”

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.
39

40.  Training personnel for IQ/OQ execution.
 The purpose of the equipment/ system.
 Use of test equipment
 Applicable SOP’s
 cGMP documentation of training
 Document all training
 Periodically review training requirements
40

41.  A document that summarizes and analyses
the test results at the end of PQ.
 Provides a conclusion about the ability of the
system to consistently meet acceptance
criteria.
 May be a stand alone document at each
stage of IQ/OQ and PQ to summarize results.

52

53. Residual Limits must be………….

FDA does not set acceptance specifications
(limits).
53

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
