Introduction The concept of validation was first proposed by Food and Drug
Administration(FDA) officials, Ted Byers and Bud Loftus, in the
mid 1970s in order to improve the quality of pharmaceuticals.
Validation is "Establishing documented evidence that provides a
high degree of assurance that a specific process will consistently
produce a product meeting its pre-determined specifications and
quality attributes.
This is to maintain and assure a higher degree of quality of food
and drug products.

Documentation of ValidationThe validation activity cannot be completed without proper
documentation of each and every minute activity with utmost details.
Documentation of validation is generally different types such as:
Validation Master Plan(VMP)
Validation Protocol(VP)
Validation Reports(VR)
Standard Operating Procedure(SOP)

Advantages :
It gives idea about future performed: What activities are to be performed?
Who is going to perform these activities?
When the activities should start and when
they should get over?
What documents will be generated?
What the policy on revalidation?
Validation master plan

Process validation Definition As per FDA Nov.2008,‘The collection of data from the process
design stage throughout production,which establishes scientific
evidence that a process is capable of consistently delivering quality
products.

Cleaning validation :Definition: “A process of attaining and documenting sufficient
evidence to give reasonable assurance, given the current state of Science
and Technology, that the cleaning process under consideration does, and
/ or will do, what it purpoes to do.”
Objective.. To minimize cross contamination.
To determine efficiency of cleaning process.
To do troubleshooting in case problem identified in the
cleaning process and give suggestions to improve the process.

Equipment Validation
Definition As per FDA, May 1987,‘Action of proving that any
equipment works correctly and leads to the expected result is
equipment qualification.
It is not a single step activity but instead result from many
discrete activities.

Validation of analytical methods
Definition : “The process by, which it is established, by laboratory studies, that
the performance characteristics of the method meet the requirements for the
intended analytical application”.
Accuracy :
“The closeness of test results obtained by that method to the true value. This
accuracy should be established across its range.”
Precision:
“The degree of agreement among individual test results when the method is
applied repeatedly to multiple sampling of a homogenous sample.”
![Page 23: Pharmaceutical validation ppt Rahul Dalvi](https://reader033.vdocuments.net/reader033/viewer/2022061516/58e8d95e1a28abe06c8b45a1/html5/thumbnails/23.jpg)
23
Specificity :
“The ability to assess unequivocally the analyte in the presence of
components that may be expected to be present, such as impurities
degradation products and matrix components.”
Limit of Quantitation :
“A characteristic of quantitative assays for low levels of compounds in
sample matrices such as impurities in bulk substances and degradation
products in finished pharmaceuticals. It is the lowest amount of analyte in
a sample that can be determined with acceptable precision and accuracy
under the stated experimental conditions.”
![Page 24: Pharmaceutical validation ppt Rahul Dalvi](https://reader033.vdocuments.net/reader033/viewer/2022061516/58e8d95e1a28abe06c8b45a1/html5/thumbnails/24.jpg)
24
Range :
“Interval between the upper and lower of analyte (including these levels) that
have been demonstrated to be determined with a suitable level of precision ,
accuracy and linearity using the method as written. The range is normally
expressed in the same units as test results. ( e.g. Percentage , parts per
million, etc.) obtained by the analytical method.”
Ruggedness:
The degree of reproducibility of test results obtained by the analysis of the
same sample under a variety of conditions such as different laboratories,
different analysts, different instruments , different lots of reagents, different
elapsed assay times, different assay temperatures, different days, etc.”
![Page 25: Pharmaceutical validation ppt Rahul Dalvi](https://reader033.vdocuments.net/reader033/viewer/2022061516/58e8d95e1a28abe06c8b45a1/html5/thumbnails/25.jpg)
25
Robustness:
"A measure of its capacity to remain unaffected by small but deliberate
variations in method parameters and provides an indication of its reliability
during normal usage.”
Linearity :
“Its ability to elicit tests that are directly or by a well defined mathematical
transformations proportional to the concentration of analyte in samples
within a given range.”
Limit of Detection :
The lowest amount of analyte in a sample that can be detected but not
necessarily quantitated, under the stated experimental conditions.”

Conclusion Validation has been proven assurance for the process efficiency and
sturdiness and it is the full fledged quality attributing tool for the
pharmaceutical industries.
Validation is the commonest word in the areas of drug development,
manufacturing and specification of finished products. It also renders
reduction in the cost linked with process monitoring, sampling and
testing.
Apart from all the consistency and reliability of a validated process
to produce a quality product is the very important for an industry.
