The document discusses various guidelines issued by the US Food and Drug Administration (FDA) regarding products regulated by the FDA, such as foods, drugs, medical devices, biologics, cosmetics, and radiation emitting products. It also provides details on FDA guidelines for toxicological studies, clinical trials, manufacturing sterile products, MRI safety, transport temperature maintenance, and clinical trial phases. Guidelines are presented for topics like food packaging, color additives, and maintaining quality control and assurance in accordance with FDA standards.

Usfda guidelines (1)
1.
2. Introduction
The various guidelines given by United
States Food and Drug administration
are:
For the maintenance and for conducting the
toxicological studies
Bioequivalence studies
Clinical trials and
In the field of radiology
3. Products Regulated by FDA

Dietary Supplements
Nutrition
Food Borne illness etc.
Drugs:
Prescription
Over the counter

5. Guidelines
1. Manufacturing of sterile products
Produced by the FDA in USA and published
in 1987
FDA defines 2 areas in aseptic processing
that are of particular importance to drug
product quality
○ Critical area
Activities that are conducted in this area include
manipulations of the sterilized materials or products
prior to and during filling or closing operations
○ Controlled area
Packing and labeling is done
6. 2. Guidelines for Radiological Health – MRI
Although MRI does not use ionizing radiation to
produce images, there are still some important
safety considerations which one should be
familiar with. These concern the use of;
○ Strong magnetic fields
○ Radio frequency energy
○ Time varying magnetic fields
○ Cryogenic liquids
○ Magnetic field gradients
7. The US FDA safety guidelines states the field
strengths not exceeding 2 tesla may be routinely
used.
People with pacemakers must not be exposed
to magnetic fields > 5 Gauss.
The RF energy form in imaging sequence can
cause heating of the tissues in the body.
The SAR is the limiting measure for the RF
energy
○ SAR = watts/Kg
○ SAR for the whole body must be < 0.4w/kg
○ Must be < 3.0w/kg averaged over the head
8. Any pulse sequence must not rise the temp
by more than 1 deg C and not greater than
38 deg C in the head, 39 deg C in trunk and
40 deg C in the extremities.
Imaging gradients do produce high acoustic
noise levels.
○ The American limits the peak acoustic noise to
200 Pascal or 140 decibels with references to
20 micropascals
○ The sounds may be due to the turning on and
off of the magnetic field gradients in various
imaging sequences.
9. 3. Maintenance of storage temperature
conditions during transport.
Drug efficacy depends on proper temperature
management
Uniquely patented flexible ice blanket design can be
layered over, under or wrapped around products for
a blanket of protection. This keeps the product
insulated from outside temperatures.
While minimizing shipping damage and
contamination, many leading pharmaceutical
companies are choosing cryopak in response to the
increasing US Pharmacopeia and US FDA
involvement with cold chain management practices
and strict enforcement of the industries food
manufacturing practices.
10. 4. Food, Seafood and Perishables
The important aspect of USFDA compliance is that
the ability to keep fragile seafood products in the
critical temperature range of 32 to 40oF during
shipping, handling and storage .
Even after melting it continues to deliver high quality,
fresh product to customer's doorstep.
The patented cryopak flexible pouch design is easy
to custom fit to virtually any size or type of seafood
shipment.
11. 5. Guide lines for clinical trials
These guidelines have been evolved wih
consideration of WHO, ICH, USFDA and European
GCP guidelines as well as the ethical guidelines for
biochemical research on human subjects issued by
the Indian council for medical Research.
They should be followed for carrying out research at
all stages of drug development, whether prior or
subsequent to product registration.
Clinical trial is a systematic study of pharmaceutical products
on human subjects in order to discover or verify the clinical
and/or adverse effects wih the subject of determining their
safety and/or efficacy.
12. Phase-I: Human/Clinical
Pharmacology trials
The objective is to determine the maximum
tolerated dose in humans,
pharmacodynamics effect, adverse
effect/reactions if any.
These are often carried out in healthy
volunteers.
At least two subjects should be used in
each dose.
These are carried out by investigators
trained in clinical pharmacology and having
the necessary facilities to closely observe
and monitor the subjects.
13. Phase-II: Exploratory trials
Limited number of patients are studied to
determine possible effects.
Studied to determine possible therapeutic
uses, effective dose range and further
evaluation of safety and pharmacokinetics.
10-12 subjects should be studied at each
dose levels.
14. Phase-III: Confirmatory
trials
The purpose of these trials is to obtain
sufficient evidence about the efficacy and
safety of the drug in a larger number of
patients.
Data on ADRs observed during clinical use
of the drug should be reported.
The report on its efficacy in the prescribed
format as per USFDA guidelines should be
submitted.
15. Phase-IV
These studies are performed after
marketing of the pharmaceutical products.
All clinical trials should be according to the
GCP.
Prerequisites for the study are-
Investigational pharmaceutical product.
Pre-clinical supporting data
16. Protocol :Relevant
components of protocol
General Information
Objectives and justification
ethical considerations
study design
Inclusion, exclusion and with drawal of
subjects

17. Clinical Trials for Vaccines
Some Vaccines that contain active or live
attenuated organisms can possibly posses
a small risk of producing particular
infection.
The subjects to be vaccinated should be
informed .
Guidelines for the clinical trials of medical
devices and diagnostic agents are also
stated.

25. Guidelines for maintenance
of quality control and
assurance
The assurance of product quality
depends more on the responsibility of
maintaining product quality during
production than thus proper sampling
and adequate testings of various
components and finished goods.

cosmetics C restriction of NMT 0.75mg to be

27. Guidelines for packing
materials
When the FDA evaluates a drug, the agency must be
firmly convenient that the package for a specific drug
will preserve the drugs efficacy as well as its purity
identity, strength and quality for its entire shelf life.
FDA does not approve containers as such but only
materials used in the container.
A list of substances considered 'generally recognized
as safe '(GRAS) has been published by the FDA.
A material which is not included under (GRAS) is
intended to be used where food must be tested by the
manufacturer and data must be subjected.
