GLP Flashcards
When was GLP developed?
1970
GLP was developed in response to
Fraudulent scientific safety studies
They performed about 35-40% of all US TOXICOLOGY TESTING
Industrial Bio-test Laboratories
FDA GLP was
PROPOSED in
FINALIZED in
EFFECTIVE in
1976
1978
1979
OECD GLP was developed and published in
1981
FDA decision is to introduce a NEW REGULATION to cover the
Non-clinical safety studies
GLP promotes
Quality and validity
GLP helps scientists obtain results which are
Reliable
Repeatable
Auditable
Recognized
GLP is a quality system with ORGANIZATIONAL process and CONDITIONS under which non-clinical health and environmental studies are
Planned
Performed
Monitored
Recorded
Archived
Reporter
GLP is a what SYSTEM and MECHANISM
Quality Management System
Regulatory Control Mechanism
Quality management is to ensure
Quality
Consistency
Accuracy
Integrity
Regulatory Control Mechanism is for
Quality
Safety
Institutions should assign ROLES and RESPONSIBILITIES to ensure
Food operational management
Is GLP DIRECTLY concerned with the SCIENTIFIC DESIGN of studies?
No
ADHERENCE to GLP will REMOVE
Sources of error and uncertainty = overall CREDIBILITY
Advantages of GLP
True reflection of results
Preclinical and residue safety
High quality and reliable data
Mutual acceptance
Increase public confidence
Shortens time-to-market
Disadvantages of GLP
More manpower
Expensive
Time consuming
Why is GLP time consuming
It is a SYSTEMATIC PROCESS that needs approval in every steps = NO SHORTCUT
The GLP principles in their REGULATORY SENSE, apply only to studies which
Non-clinical (animals and in vitro)
Data on properties and safety
Submitted to NATIONAL REGISTRATION AUTHORITY for registering or licensing
The GLP requirements for non-clinical laboratory studies conducted to EVALUATE DRUG SAFETY over the following classes of studies
Single dose toxicity
Repeated dose toxicity
Reproductive toxicity
Mutagenic potential
Carcinogenic potential
Toxicokinetics
Pharmacodynamic studies
Local tolerance tests
Repeated dose toxicity includes
Sub-acute
Chronic
Reproductive toxicity includes
Fertility
Embryo-foetal toxicity
Teratogenicity
Peri/post natal toxicity
Local tolerance tests include
Photo toxicity
Irritation and sensitisation
Addictive or withdrawal effects

OVERSEES all studies
Study director
Suitable size, spacious
Adequate degree of SEPARATION of different activities
Organized WORKFLOW
Well VENTILATED and CLEAN
Facility design
SECURE storage and RETRIEVAL if study plans, raw data, final report and specimens.
Archived facilities
What does archive facilities SECURE and STORE
Study plans
Raw data
Final report
Specimens
Appropriate COLLECTION, STORAGE and DISPOSAL facilities and DECONTAMINATION procedures
Waste disposal
Located AWAY from testing laboratories (separate building)
SEPARATE AREA for animals, diagnosis, treatment and control of animals
Animal care facilities
CONTAMINATION RISK of animal care facilities is reduced by
Barrier system
Clean and dirty corridors
What to CONSIDER in animal care facilities
Lighting
Noise
Temperature
Documented program to ensure SUITABILITY and CALIBRATION
Adequate design and capacity
LOGBOOKS for each
Equipment
It is done for ACCURACY of measurements
Calibration
Test item vs. test system
TI: compound you are investigating
TS: experimental protocol
Questions for test item vs. test system
TI: WHEN and WHAT part did you get
TS: HOW will you administer it
CHARACTERISTICS of a test item
Test item identity
Test item identity includes
Potency
Composition
Stability
Purity/impurity
Formulation and dosing record
CHEMICAL ANALYSIS
Test item
CHARACTERISATION of plant material
Fresh or dried
Climatic condition
Plant part
Ration of sample to solvent
Characterisation choice of vehicle
INTERACTION of the vehicle with the active constituent
PH
Procurement
