7Sagar Kishor Savale04/21/16

8. Reasons for building a pilot plant
To evaluate on process of
large change in scale up
operation.
To find and examine all by-
products or waste .
To produce a trail lot of
quantities of material.
Clinical studies, analytical
development, process dev-
elopment, stability testing.
8Sagar Kishor Savale04/21/16

9. Why conduct Pilot Plant Studies?
A pilot plant allows investigation of a product and process on
an intermediate scale before large amounts of money are
committed to full-scale production.
It is usually not possible to predict the effects of a many-fold
increase in scale.
It is not possible to design a large scale processing plant from
laboratory data alone with any degree of success.

batches
Sagar Kishor Savale04/21/16

12. Laboratory scale batch
• Early development at laboratory stage.
• It is generally 100-1000 times less than production batch.
• It is 1X (3-10 kg or 3-10 liters or 3000-10000 unit) batch.
Uses
• To support formulation.
• For packaging development.
• For preclinical trial.
12Sagar Kishor Savale04/21/16

13. Pre-exhibit batch
• It is 1st
step in scale up.
• It generally 70 % of the size of the exhibit batch.
• It prepaid with the complete process documentation and fully
validated analytical methodology.
Uses
• To detect any problem arise in manufacture of exhibit batch .
13Sagar Kishor Savale04/21/16

14. Exhibit batch
It is demonstration batch.
It contains the mfg. documentation, product specification,
accelerated stability data submitted to FDA.
It generally 10 % of the production scale batch.
It is 10X (30-100 kg or 30-100 liters or 30000-100000 unit)
batch .
It is manufactured under GMP.
Exhibit batch also called as :-
NDA or ANDA batch
Regulatory reference batch
Bioequivalence batch
Fully GMP batch
Stability tested batch
14Sagar Kishor Savale04/21/16

15. Production batch
It is produced during the routine marketing of product.
It is 100X batch means :- 300-1000 kg or
300-1000 liters or
300000-1000000 unit
15Sagar Kishor Savale04/21/16

16. Scientific scale up
Should done in incremental manner.
Process being validated for each new scale.
The equipment should possess following similarity
1) Geometric similarity
2) Kinematic similarity
3) Dynamic similarity
16Sagar Kishor Savale04/21/16

17. Geometric similarity
Dimensions of equipment in all scale up should have same
ratio such as like,
Vessel diameter
Impeller diameter
Baffle widths
17Sagar Kishor Savale04/21/16

18. Kinematic similarity
This requires all corresponding
point in each system to have the
same ratio.
18
Dynamic similarity
 This requires equal force ratio at corresponding point of
the system like,
Gravitation
Surface tension
Viscosity
Sagar Kishor Savale04/21/16

19. General considerations
1. Reporting Responsibility
R & D group with
separate staffing
The formulator who developed the
product can take into the
production and can provide support
even after transition into
production has been completed.
19Sagar Kishor Savale04/21/16

20. Scientists with experience in
pilot plant operations as well as in
actual production area are the
most preferable.
As they have to understand the
intent of the formulator as well as
understand the perspective of the
production personnel.
The group should have some
personnel with engineering
knowledge as well as scale up
also involves engineering
principles.
2. Personnel Requirement:-
20Sagar Kishor Savale04/21/16

21. 3.Space Requirements
Administration
and information
processing
Physical
testing area
Standard
equipment
floor space
Storage
area
21Sagar Kishor Savale04/21/16

22.  Administration and information process:
Adequate office and desk space should be provided for both
scientist and technicians.
The space should be adjacent to the working area.
22Sagar Kishor Savale04/21/16

23.  Physical testing area:-
This area should provide permanent bench top space for
routinely used physical- testing equipment.
23Sagar Kishor Savale04/21/16

24.  Standard pilot-plant equipment floor space:-
Discreet pilot plant space, where the equipment needed for
manufacturing all types of dosage form is located.
Intermediate – sized and full scale production equipment is
essential in evaluating the effects of scale-up of research
formulations and processes
Equipments used should be made portable where ever possible. So
that after use it can be stored in the small store room.
Space for cleaning of the equipment should be also provided.
24Sagar Kishor Savale04/21/16

25. It should have two areas divided
as approved and unapproved area
for active ingredient as well as
excipient.
Different areas should provided
for the storage of the in-process
materials, finished bulk products
from the pilot-plant & materials
from the experimental scale-up
batches made in the production.
Storage area for the packing
material should also be provided.
 Storage Area:-
25Sagar Kishor Savale04/21/16

26. 4. Review of the formula:-
A thorough review of the each
aspect of formulation is important.
The purpose of each ingredient
and it’s contribution to the final
product manufactured on the
small-scale laboratory equipment
should be understood.
Then the effect of scale-up using
equipment that may subject the
product to stresses of different
types and degrees can more readily
be predicted, or recognized.
26Sagar Kishor Savale04/21/16

27. 5. Raw materials:-
One purpose/responsibility of the pilot-plant is the approval &
validation of the active ingredient & excipients raw materials.
Raw materials used in the small scale production cannot
necessarily be the representative for the large scale production
27
Why?
Sagar Kishor Savale04/21/16

28. 6. Equipment:-
The most economical and the simplest & efficient equipment
which are capable of producing product within the proposed
specifications are used.
The size of the equipment should be such that the experimental
trials run should be relevant to the production sized batches.
If the equipment is too small the process developed will not
scale up.
Whereas if equipment is too big then the wastage of the
expensive active ingredients.
28Sagar Kishor Savale04/21/16

29. 7. Production Rates:-
The immediate as well as the future market trends/requirements are
considered while determining the production rates.

30Sagar Kishor Savale04/21/16

31.  Why to carry out process evaluation????
The knowledge of the effects of various process parameters
as few mentioned above form the basis for process
optimization and validation.
31Sagar Kishor Savale04/21/16

32. 9. Master Manufacturing Procedures:-
The three important aspects
Weight sheet Processing
directions
Manufacturing
procedure
32Sagar Kishor Savale04/21/16

33. The weight sheet should clearly identify the chemicals required
In a batch. To prevent confusion the names and identifying nos.
for the ingredients should be used on batch records.
The process directions should be precise and explicit.
A manufacturing procedure should be written by the actual
operator.
Various specifications like addition rates, mixing time, mixing
speed, heating, and cooling rates, temperature, storing of the
finished product samples should be mentioned in the batch
record directions. 33Sagar Kishor Savale04/21/16

34. 10. Product stability and uniformity:-
The primary objective of the pilot
plant is the physical as well as
chemical stability of the products.
Hence each pilot batch representing
the final formulation and
manufacturing procedure should be
studied for stability.
Stability studies should be carried
out in finished packages as well.
34Sagar Kishor Savale04/21/16

35. Scale-up and post approval changes
(SUPAC)
FDA and American Association of Pharmaceutical Scientists
(AAPS) provided the scientific foundation for the scale up and
post approval changes required for immediate release product
Called as SUPAC.
It provide guideline for post approval changes in the following

36Sagar Kishor Savale04/21/16

37. Significance of pilot plant
Examination of formulae.
Review of range of relevant processing equipments.
production rate adjustment.
Idea about physical space required.
Appropriate records and reports to support GMP.
Identification of critical features to maintain quality.
37Sagar Kishor Savale04/21/16

38. A pilot plant can be used for
Evaluating the results of laboratory studies and making product and
process corrections and improvements.
Producing small quantities of product for sensory, chemical,
microbiological evaluations, limited market testing or furnishing
samples to potential customers, shelf-life and storage stability studies.
Providing data that can be used in making a decision on whether or
not to proceed to a full-scale production process; and in the case of a
positive decision, designing and constructing a full-size plant or
modifying an existing plant.
38Sagar Kishor Savale04/21/16

39. Advantages
Members of the production and quality control divisions can
readily observe scale up runs.
Supplies of excipients & drugs, cleared by the quality control
division, can be drawn from the more spacious areas provided
to the production division.
Access to engineering department personnel is provided for
equipment installation, maintenance and repair.
39Sagar Kishor Savale04/21/16

40. Disadvantages
The frequency of direct interaction of the formulator with the
production personnel in the manufacturing area will be
reduced.
Any problem in manufacturing will be directed towards it’s
own pilot-plant personnel's.
40Sagar Kishor Savale04/21/16

41. Pilot Plant design for Tablets
41Sagar Kishor Savale04/21/16

42. The primary responsibility of the pilot plant staff is to ensure
that the newly formulated tablets developed by product
development personnel will prove to be efficiently,
economically, and consistently reproducible on a production
scale.
The design and construction of the pharmaceutical pilot plant
for tablet development should incorporate features necessary to
facilitate maintenance and cleanliness.
If possible, it should be located on the ground floor to expedite
the delivery and shipment of supplies.
42Sagar Kishor Savale04/21/16

43. Extraneous and microbiological contamination must be guarded
against by incorporating the following features in the pilot plant
design:
1.Fluorescent lighting fixtures should be the ceiling flush type.
2.The various operating areas should have floor drains to simplify
cleaning.
3.The area should be air-conditioned and humidity controlled.
4.High -density concrete floors should be installed.
5.The walls in the processing and packaging areas should be
enamel cement finish on concrete.
6.Equipment in the pharmaceutical pilot plant should be similar to
that used by production division- manufacture of tablets.
