• Introduction:- investigational drugs are those drugs or mixture or
chemical which are not released and certified by the food and drug
administration for the general use and sale for commercial concern. These
drugs usually stand the statement on their labels as ‘caution: New Drug-

principle investigator who is the member of medical staff of hospital after
obtaining consent by duly sign the food and drug release for the
manufacture of respective investigational drugs.
• Principle
• Hospital are the primary centers for clinical investigational on drug.
• Investigational drug should be used only under the direct supervision of
the principle investigator who should be member of medical staff and who
should assumed the burden of securing the necessary consent.
• When nurses are called upon to administer investigational drug they
should have available to them basic information concerning such drugs
including dosage form strength available, action and uses, side effect and
symptoms of toxicity etc.

3. Classification of investigational new drug
Class A:
• This class should contain all investigational use drugs which are under the
preliminary experiment stage .
• these drugs are restricted to use only by principle investigator.
Class B:
• This class of investigational drug has passed through preliminary
experimental research stage. In this class the investigational drugs are
supplied to pharmacy department by principle investigator and are only
dispensed after obtaining of his written prescription which duly sign.
Class C:
• This class of investigational use of drug approved by the USP, NF, or passed
by the federal FDA for use and sale as commercial concern. These drugs
may be used only in hospital setup for their patient under the supervision
of medical staff after fulfillment of specific procedure
Class D:
• These class of drug have been accepted for use in hospital and are listed in

are subjected to review by advisory committee which are nothing by the
committee on the human use in research and pharmacy and therapeutic
committee (PTC) in which the principle investigator should provide all the
information related to investigational drug to the PTC and should letter for
intention to use of investigational drug in patient.
• It is the responsibilities of hospital and member of PTC to develop procedure
and policies for holding of investigational drugs in the hospital for patient
benefits.

6. Control of investigational use of drug
• All investigational drug should be registered with the pharmacy and
therapeutic committee. This may be accomplished bay a latter from the
principle investigator, which provide the following information.
1. New drug name
2. Generic Name
3. Manufacturer
4. Chemical name
5. Proprietary Name
6. General chemistry
7. Pharmacology
8. Toxicology
9. Dose Range
10. Method of Administration
11. Antidote
12. Therapeutic uses

7. • In order to control the use of investigational drugs many pharmacist have
developed various forms which may be used to disseminate the above
information on an investigational use drug to the various staff doctors and
nurses.
• The forms are usually titled.
1. Physician’s data sheet on investigational drug

3) Strength/ Dosage forms
4) Amount Received
5) Date received.

• During this stage the pharmacist can play an important role by assisting in
the development of the protocol and the control of double blind
test/study having the experimental drug or placebo prepared exactly the
same dosage forms and presentation. Neither the present nor the doctor
informed as to whether the placebo and the potent article .
• Collecting, storing and distributing essential information concerning the
drug being studied.
• Packing and labeling investigational drug in multiple or unit dosage
containers.
• Preparing dosage forms
• Dispensing of investigational drug to both inpatient or outpatient

11. • Advisory committee for the investigational use of drug.
1. the pharmacy and therapeutic committee
2. FDA advisory committee system.
1) The pharmacy and therapeutic committee (PTC)
• The PTC is a group of person which formulate policies regarding evaluation
and therapeutic use of investigational drug.
• The committee is composed of physician, Pharmacist and other health care
professionals with the inclusion of medical staff.

drug institute (Lucknow) Drug controller central of India. AIMS (New Delhi)
PGI Chandigarh for consultation of adverse drug reaction of investigational
drug.

12. • FDA advisory committee system
• FDA advisory committee provide technical assistance related to the
development and evaluation of investigational drug. Biologics and medical
device.
• The primary role of FDA advisory committee is to provide independent
expert scientific advice to the agency in its evaluation of investigational
drug any stage of consideration by the agency.
