2. GLP
• GLPs can be defined as “a body of rules, operating procedures
and practices established by a given organization that are
concerned to be mandatory with a view to ensure quality and
correctness in the results produced by a factory”.
2
3. • GLP is a regulation.
• Established by worldwide bodies such as Organization
for Economic Cooperation and Development(OECD) and
ISO.
• The objective is not only quality of data but also
traceability and integrity of data.
• Contain two common elements:
1. SOPs
2. Quality Assurance Unit(QAU).
3
4. REQUIREMENTS OF GLP
• Responsibilities should be defined for the sponsor
management, for study management and for QAU.
• All routine works should follow SOPs.
• Facilities such as laboratories should be large enough
and have the right construction to ensure the integrity of
a study.
4
5. • Test and control articles should have the right quality
and instruments should be calibrated and well
maintained.
• People should be trained or otherwise qualified for the
job.
• Raw data and other data should be acquired, processed
and archived to ensure integrity of data.
5
6. SCOPE OF GLP
• “The non clinical safety testing of test items contained in
the pharmaceutical products, pesticide products,
cosmetic products, veterinary drugs as well as food
additives, feed additives, and industrial chemicals.
• Obtain data on their properties and/or their safety with
respect to human health and/ or the environment”.
(OECD, 1998)

• Provide detailed descriptions of activities performed by
the laboratory.
• Eg: sample custody chain, sample handling and
preparation, analytical method, instrument
maintenance, record keeping etc.
10
11. • Preferably written in the laboratory close to the
instrument.
• It should be either written or thoroughly reviwed by the
instrument operators.
• Not be written to explain how procedures are supposed
to work, but how they work.
11
12. QAU
• Responsible for implementing quality procedure and
assessing them on a continuing basis, this will include
audits of the laboratory from time to time.
• Certify that every step of the analysis is valid.
• Serves as an internal control function.
12
13. RESPONSIBILITIES OF QAU
• Maintain copy of master schedule sheet of all studies
conducted.
• Maintain copies of all protocols pertaining to the studies
for which QUA is responsible.
• Inspect studies at intervals adequate to assure the
integrity of the study .
• Maintain written and signed records of each periodic
inspection.
• Submit written status reports on each study.
13
14. • Determine whether deviations from protocols and SOPs
were made with proper authorization and documentation.
• Review the final study report.
• Audit the correctness of the statement, made by the study
director, on the GLP compliance of the study.
• Prepare and sign a statement that specifies the dates of
audits and dates of reports to management and to the
study director.
14
15. Protocol for conduct of non clinical
testing.
• A single protocol cover only one single experiment using
the same test article in a single type of test system.
• Indicates what will be done and when will be done.
• The exceptions from SOPs applied to the study should be
described in the protocol.
• List the SOPs used in the study.

measurements to be made.
The records to be maintained.
The date and approval of the protocol by the sponsor .
Statement for proposed statistical method to be used.
18. Control on animal house
• The facility should be designed and operated in order to
minimize the effects of environmental variables on animals.
• Enough space for animals &studies to be separated & allow
operators to work efficiently.
• The environment and control system should maintain the
temperature, humidity and air flow.
• The surface of walls , doors , floors should be constructed to
allow easy & complete cleaning .
18
19. • The simplest form of animal house should have 4
departments:
1. Normal animals.
2. Experimental animals.
3. Clean storage for food and feeding.
4. Washing , cleaning and incinerating.

Quality Guidelines: Relate to the quality
area & include critical milestones such as
the carrying out stability studies, definition
of appropriate thresholds for impurities
testing, as well as evolving a flexible
approach to GMP risk management based
pharmaceutical quality
Safety Guidelines: ICH guidelines have
created a full list of safety guidelines aimed
at unearthing potential risk areas of
research like genotoxicity, carcinogenicity
& reprotoxicity
Efficacy Guidelines: ICH guidelines
relating to efficacy relate to areas such as
the conduct, design safety & reporting of
clinical trials. It also covers medicines
derived from biotechnological processes &
having used pharmacogenetics or
genomics techniques aimed at producing
better targeted medicines.
Multidisciplinary Guidelines: it covers
all those topics not covered in the quality,
safety &efficacy guidelines.ICH medical
terminology(MedDRA), CTD & the
development of ESTRI are the core aspects
of ICH guidelines in this area.
