4. INTRODUCTION
 Formulation and development is a process of
selection of component and processing.
 Now days computer tools used in the formulation
and development of pharmaceutical product.
 Various technique, such as design of experiment
are implemented for optimization of formulation and
processing parameter.
4

5.  Traditionally optimization in pharmaceuticals refer
changing one variable at a one time, so to obtain
solution of a problematic formulation.

6.  Pharmaceutical formulation,
in pharmaceutics, is the process in
which different chemical
substances, including the
active drug, are combined to
produce a final medicinal product.
The word formulation is often used
in a way that includes dosage form

7. EMULSION
 An emulsion is a biphasic liquid dosage form which
are immiscible in one another and get miscible by
the addition of emulsifying agent.

8. MICRO EMULSION
 Microemulsion are clear ,thermodynamically stable,
isotropic liquid mixtures of oil, water and surfactant
frequently in combination with co surfactant.
 The aqueous phase may contain salt or other
ingredients and the “oil” may actually be a complex
mixture of different hydrocarbons.

9. SOFTWARE SALIENT FEATURES
Design Expert Powerful and compressive
package used for optimizing
formulation and process.
Minitab Powerful DoE software for
automated data analysis
MS-Excel
compatibility.Include almost
all design of RSM
DOE PRO XL MS-Excel compatibility DOE
SOFTWARE for
automated data analysis.
CARD Powerful DOE software for
data analysis include
graphics and help features.

10. DESIGN OF EXPERIMENT
 Design of experiment is a structure organised
method used to determine the factor affecting
to process and output of that process.
 Palsimony principle:
 Some of factor are important while other are
not important
 Few variable are effective while other are not
effective.
 Experimental design are integral part of
optimization technique.
 Those technique use in formulation
optimization

11. DOE FOR FORMULATION DEVELOPMENT
 All pharmaceutical products are formulated to
specific
dosage form.
 Drugs to be effectively delivered to patient typical
pharmaceutical dosage form include tablets,
capsules, solution suspension, etc.
 Different dosage form required different technology
usually present different technological challenge for
formulation & development .

12.  Due to complex challenges,
formulations scientist used effective
methodology
 Like as design of experiment and
statistical analysis for formulation and
development
 Formulation scientist used this
method for process optimization and
process seminar.

17. LEGAL PROTECTION OF INNOVATIVE USES OF
COMPUTER IN R&D
 Intellectual Property Right:
 Patent
 Copyright
 Protection database
 Trade secret

18. INTELLECTUAL PROPERTY RIGHT
 IPR are used to describe the legal instruments for
protecting innovation.
 These allow creator or owner of patent trademark
or copyright work to benefit from their work or
investment in a work.
18

19. PATENT
 Patents are most important and strongest
intellectual property .
 Patent protects invention or technical innovation.
 Patent is an exclusive legal right granted for an
invention that is:
I. New (novelty)
II. Involves an innovative step (non obvious)
III. Capable of industrial application.
19

20. COPYRIGHT
 Copyright is traditionally used to protect literally
works of art from copying .

22. PROTECTION DATABASE
 In addition to patenting of database structure a
database can be protected either by copyright
protection or by database rights.

23. TRADE SECRET
 Tradesecret as information including
formula, pattern, compilation, programe
device, method technique or processes.
