31. What are deviation & its types?
Deviation is
departure from the approved instructions /established standards.
There are two
types of deviation and given below:
Controlled /
planned deviation:
·
Any deviation from documented
procedure opted deliberately for temporary period to manage unavoidable
situation or improving the performance of the operations, without affecting the
quality & yield of drug substance and safety of the operations shall be
termed as controlled / planned deviation.
Uncontrolled /
unplanned deviation:
·
Any deviation occurred in
unplanned or uncontrolled manner such as system failure or equipment breakdown
or manual error shall be termed as uncontrolled / unplanned deviation.

32. What are change control and its types?
Change control
is a system that control change by
- Identifying ownership of the change
- Allowing for review and approval of the change.
- Preventing changes that could adversely affect product quality or conflict with registration or regulatory requirement.
- Providing an assessment of change and monitors the impact of change.
Level 1 (Minor)
are those that are unlikely to have any detectable impact on the quality
attributes of the product.
Level 2 (Major)
are those that are likely to have a significant impact on the quality
attributes of the product.
The type of
reasons for change control
- Regulatory requirement
- GMP implementation / enhancement
- Quality improvement
- Capacity enhancement
- Introduction of new product in existing facility
- Cost reduction
- Automation
- Aging of facility
- To manage the unavoidable situation
- Market requirement

Batch Number:
A unique
combination of numbers, letters, and/or symbols which identifies a batch (or
lot) and from which the production and distribution history can be determined
Batch:
A specific
quantity of material produced in a process or series of processes so that it is
expected to be homogeneous within specified limits. In the case of continuous
production, a batch may correspond to a defined fraction of the production.
Batch size may be defined either by a fixed quantity or the amount produced in
a fixed time interval.
Contamination:
The undesired
introduction of impurities of a chemical or Microbiological nature, or of
foreign matter, in to or onto a raw material, intermediate, or API during
production, sampling, packaging or repackaging, storage or transport.
Cross-contamination:
Contamination
of a material or of a product with another material or product.
Quarantine:
The status of
materials isolated physically or by other effective means pending a decision on
their subsequent approval or rejection.
Critical process parameters:
A process parameter whose variability has an
impact on a critical quality attribute and therefore should be monitored or
controlled to ensure the process produces the desired quality.
Mother liquor:
The residual
liquid which remains after the crystallization or isolation processes. Mother
liquor may contain un-reacted materials, intermediates, levels of the API
and/or impurities. It may be used for further processing.
OOS:
Out of
Specification (OOS) results are those results, generated during testing that do
not comply with the relevant specification or standards or with the defined
acceptance criteria.
Theoretical yield:
The quantity
that would be produced at any appropriate phase of production, based upon the
quantity of material to be used, in the absence of any loss or error in actual production.
Expected yield:
The quantity of
material or the percentage of theoretical yield anticipated at any appropriate
phase of production based on previous laboratory, pilot scale, or manufacturing
data.
CAPA is the
Corrective Action & Preventive Action.
Corrective Action:
Action taken to
eliminate the causes of an existing non-conformity, defect or other undesirable
situation to prevent recurrence
[Actions taken after the occurrence of a defect
or problem to stop the same from recurrence]
Preventive Action:
Action taken to
eliminate the causes of potential non-conformity, defect or other undesirable situation
to prevent occurrence
[Actions
initiated before the occurrence of a defect or problem to prevent the same
occurrence].
Installation Qualification (IQ):
Establishing
high degree of confidence that the equipment as installed is consistent with
manufacture’s requirements and specifications.
Operating Qualification (OQ):
Establishing a
high degree of confidence that the equipment as installed is able to
consistently operate within established limits and tolerances.
Performance Qualification (PQ):
Establishing a
high degree of confidence, with appropriate testing that the equipment, under
normal operating conditions, will consistently produce a quality product.

34. What is the ICH? Write its aim/purpose and names of the different parties & different regions?
ICH means
“International conference on harmonization”.
Aim/Purpose:
“Ensure good
quality, safety and effective medicines are developed and registered in the
most effective manner, through harmonization of technical requirements”
Different Parties:
1. European
commission – European Union (EMEA)
2. European
Federation of Pharmaceutical Industries & Association (EFPIA)
3. Minister of
health, Labor & Welfare, Japan (MHLW)
4. Japan
Pharmaceutical Manufacturers Association (JPMA)
5. US Food
& drugs Administration (FDA)
6.
Pharmaceutical Research & Manufactures of America (PhRMA)
Different regions:
1. European
Union (EMEA)
2. United
states of America (USFDA)
3. Japan (MHLW)

35. Difference between validation & testing?
Both are not
same. Testing is defined as the identification of errors (difference between expected
& actual results) in a system.
Validation is defined as documented evidence
that a system performance as expected. Validation includes testing but it is
more – for instance, checking the documents for completeness & correctness.
