History of Pharmacovigilance
In 1901, in USA: 13 children died from contaminated diphtheria antitoxin
due to which passed Biological Control Act 1902 – ensure purity and safety of
serum, vaccines and other products.
In 1937 in USA: 105 people died including 35 children due to new liquid
formulation (raspberry flavoured elixir) of anti-infective sulphanilamide. (Tablets
and powder was used before for streptococcal infections)
due to which The federal food, drug and cosmetics act (FDCA) was enacted in
1938 which began to examine the risk-benefit profile of medicinal products.
(required proof of safety through NDA)

History of Pharmacovigilance
Gradual increase in regulatory authority:
Durham-Humphrey Amendment of 1951 (FDCA amendment
1951) – separation of drugs into 2 types – drugs could be used
without the physician assistance (named over the counter drugs)
and drugs needing physician assistance.

History of Pharmacovigilance
THALIDOMIDE TRAGEDY:
Late 1950s and early 1960s – changed focus of drug safety from reactive to
proactive (mandates safety surveillance before marketing as well as post
marketing pharmacovigilance.)
1956-1961 used thalidomide in 20 different countries as sleeping pill
(hypnotic) and antiemetic in pregnant women. (but not approved for use in
USA because of its delayed NDA)
Late 1961 and early 1962 reports of various limb deformities (Phocomelia)
from Europe began.

History of Pharmacovigilance
POST THALIDOMIDE EVOLUTION:
- Necessity to monitor drug products for efficacy and safety increases.
- Regulatory changes following thalidomide tragedy:
Kefauver-Harris Amendments:
* Required affirmative approval from the FDA before a product could be
marketed. (21 CFR Part 314)
* Mandatory IND process permitting FDA monitoring of testing, transportation,
and distribution (21 CFR part 312)
* Mandate registration of subjects exposed during pre-clinical and clinical testing
(21 CFR part 50)
6. By Dr. Ramesh Bhandari
History of Pharmacovigilance
Kefauver-Harris Amendments:
* Established 3 separate phases of clinical trial to prove efficacy (21
CFR part 312)
* Required uniformly formatted drug labelling (21 CFR part
201.57)
* Established good manufacturing practices (21 CFR part 210)
* Regular post marketing communication with FDA on experience
with the drugs (all spontaneous reporting, analysis of medical
literature on product)

Origin of Pharmacovigilance
Pharmakon – Drugs
Vigilare – to watch or to see
Pharmacovigilance is the science and activities relating to the
detection, assessment, understanding and prevention of adverse
effects or any other medicine/vaccine related problem.

Origin of Pharmacovigilance
Special issues in pharmacovigilance:
Drug Name Year Removed Reason removed
Diethlylstilbestrol (DES) 1971 Vaginal tumours in girls and young
women
Phenformin 1978 Lactic acidosis
Phenolphthalein 1997 Carcinogenicity
Troglitazone 2000 Hepatotoxicity
Rofecoxib 2004 Risk of Myocardial Infarction
Rosiglitazone 2010 Increase risk of heart attack and deaths

WHO INTERNATIONAL DRUG
MONITORING PROGRAMME
Under the auspices of 10 countries, a 3 year feasibility
study of a collaborative international program of
pharmacovigilance was begun by Professor Jan Venulet in
1968 funded by USA.
Professor Venulet and the FDA’s Drug safety group
developed a thesaurus DART, to describe spontaneous
report in uniform body system based terminology.
11. By Dr. Ramesh Bhandari
WHO INTERNATIONAL DRUG
MONITORING PROGRAMME
Later in FDA, DART evolved into COSTART (Coding
symbols for thesaurus of adverse reaction terms).
COSTART used until MedDRA (Medical terminology for
drug regulatory authorities) was adopted in later 1990s by
the European commission as a part of ICH.
12. By Dr. Ramesh Bhandari
WHO INTERNATIONAL DRUG
MONITORING PROGRAMME
Venulet developed a program agreed to by members states for
recording, storing, and retrieving incoming spontaneous reports into a
database, as well as methodologies for analysing the data received.
This is known as International Drug Monitoring Programme which
then moved to WHO headquarters in Geneva, Switzerland.
In 1978, the program was moved to Uppsala, Sweden.
13. By Dr. Ramesh Bhandari
WHO INTERNATIONAL DRUG
MONITORING PROGRAMME
Uppsala Monitoring centre’s mission is to Safeguard patients and to:
Lead the research and development tools and methodologies for
pharmacovigilance and patient safety
Lead and support global pharmacovigilance activities
Develop effective networks and sustainable pharmacovigilance system
Apply best practices in communication and networking with stakeholders
Provide high quality and cost effective tools, services and international
dictionaries, classification and terminologies for pharmacovigilance and
patient safety
Build an effective organization for the future
14. By Dr. Ramesh Bhandari
WHO INTERNATIONAL DRUG
MONITORING PROGRAMME
This monitoring program now serves over 80 countries
with annual meeting exchange practices, provide training,
and serve as a database of adverse events from member
countries.
15. By Dr. Ramesh Bhandari
FUNCTIONS OF WHO INTERNATIONAL
DRUG MONITORING PROGRAMME
Identification and analysis of new adverse reaction signals from the
case report information submitted to the national centers.
Information exchange between WHO and national centers through
“Vigimed”
Publication of periodical newsletters
Supply of tools for management of clinical information (WHO drug
dictionary and the WHO adverse reaction terminology).
16. By Dr. Ramesh Bhandari
FUNCTIONS OF WHO INTERNATIONAL
DRUG MONITORING PROGRAMME
Training and consulting support to national centers and
countries establishing pharmacovigilance system
Computer software for case report management
Annual meeting for representatives of national centers
17. By Dr. Ramesh Bhandari
FUNCTIONS OF WHO INTERNATIONAL
DRUG MONITORING PROGRAMME
Methodological research for the development of
pharmacovigilance
Publication of various scientific articles in
pharmacovigilance.

In 1986 – Proposed ADR monitoring system for India (12
Regional Centres)
In 1997 – India joined WHO-ADR monitoring programme (3
centres i.e. AIIMS, KEM and AMU)

Then later the National coordinating centre was shifted to the Indian
Pharmacopoeia Commission (IPC), Ghaziabad, (U.P.) in 15th April,
2011.

PHARMACOVIGILANCE PROGRAM OF INDIA
(PvPI)
The PvPI Programme had been planned to be implemented in 3 phases:
1. Phase I: To set up 40 ADR Monitoring centres (AMC) would be rolled out
in 2010.
2. Phase II: To set up 140 MCI recognized medical colleges by 2011.
3. Phase III: Programme would ultimately cover the healthcare system by
