INDIAN PHARMACOVIGILANCE SYSTEM
“PRESENT STATUS AND FUTURE
CHALLENGES”
PHARMACOVIGILANCE
Pharmacovigilance is the science and activities
relating to the detection, assessment
understanding and prevention of adverse effect or
any other possible drug-related problems.
MAGNITUDE OF THE PROBLEM
In the U.S. alone 2.2 million hospitalized
patients have serious ADRs each year, of
which 106,000 have a fatal outcome
Cost of drug related morbidity and mortality
exceeds $177.4 billion annually
30% - 50% ADRs are preventable
HISTORICAL MILESTONES
1937- Over 100 people died from renal
failure due to an elixir of sulfanilamide
dissolved in diethylene glycol
1938- FDA made preclinical toxicity studies
and pre-marketing clinical trials mandatory
1950s- Aplastic anaemia shown to be due to
chloramphenicol
1960- Hospital based drug monitoring
programme started by FDA
HISTORICAL MILESTONES……..contd.
1961- Thalidomide disaster
1968- WHO established its International Drug
Monitoring Programme
1970s- Subacute myelo-optic neuropathy linked
to clioquinol
1980s & 1990s large number of drugs with
serious adverse effects
GOALS OF PHARMACOVIGILANCE
Rational and safe use of medicinal drugs
Assessment and communication of risks and
benefits of drugs on the market
Educating and informing the patients
OBJECTIVES OF PHARMACOVIGILANCE
Early detection of hitherto unknown adverse
reactions and interactions especially for the
newly marketed drugs
Detection of increase in frequency of (known)
adverse reactions
Identification of risk factors and possible
mechanisms underlying adverse reactions
Benefit-risk analysis
PLAYERS IN PHARMACOVIGILANCE
WHO
Uppsala Monitoring Centre
National Pharmacovigilance Centres
Hospitals and Academia
Healthcare professionals
Patients
Media and consumer advocacy groups

Assistance to potential members of the
Programme in developing their Pharmacovigilance
system

COUNTRIES PARTICIPATING IN THE WHO
INTERNATIOAL DRUG MOINTORING
PROGRAMME
Official Member Countries (dark Blue)
81 Countries Members
17 Countries Associate
PHARMACOVIGILANCE ….IS IT NEEDED
IN EVERY COUNTRY?
There are differences between countries in the
occurrence of adverse drug reactions due to
differences in:
drug production
drug distribution and use
genetics, diet, traditions of the people
use of non-orthodox drugs (e.g. traditional
medicines)
PHARMACOVIGILANCE - THE WIDENING
HORIZONS
Traditional and complementary medicines
Blood products & vaccines
Medical devices
Cosmetics
Counterfeit and substandard medicine
Increasing self-medication practices
Illegal sale of medicines & drugs of abuse over
the internet
Medication errors
INDIAN AWARENESS
After the clioquinol incidence.
Withdrawal of clioquinol
Establishment of DCGI centers
Program still remained dormant – till1990’s

BROAD OBJECTIVES OF PROGRAMME
To foster the culture of AE notification and
reporting
To establish a viable and broad-based ADR
monitoring program in India.
Specific objectives of the Programme
To create an ADR database for the Indian
Population
……contd.
BROAD OBJECTIVES OF PROGRAMME
To create awareness of ADR monitoring
among people
To ensure optimum safety of drug products in
Indian market
To create infrastructure for ongoing regulatory
review of PSURs
NATIONAL PHARMACOVIGILANCE
POLICY & MILESTONES
The National Pharmacovigilance Programme will have
the following milestones:
Short-term objectives: To foster a culture of
notification
Medium-term objectives: To engage several healthcare
professionals and NGOs in the drug monitoring and
information dissemination processes.
Long-term objectives: To achieve such operational
efficiencies that would make Indian National
Pharmacovigilance Programme a benchmark for global
drug monitoring endeavours.

ENVIRONMENT NOW
New medicines reaching market faster than ever
before
New science – new ADRs
Public expectations higher than ever- 60% people
assume safety guaranteed
COMMUNICATIONS ARE CRITICAL
Clear, comprehensible, targeted messages
meeting the needs of audience
Health professionals
The public
Other regulatory authorities and WHO
DRUG WITHDRWALS- THE CHALLENGES
Robust evidence
Timely decision making
Effective communications
Demonstrable protection of public health
DRUG WITHDRAWALS –THE EVIDENCE
Strengthen spontaneous reporting and signal
detection
Use epidemiological databases to strengthen
signals- and also to detect?
Look for evidence of safety as well as harm
DRUG WIDHRWALS - OPPORTUNITIES
New data sharing technology
New EU legislative power
Risk management plans
Better communications- including electronic
Public education on risk
PHARMACOVIGILANCE……………..THE
CHALLENGES AHEAD
Globalization
Broader safety concerns
Public health versus pharmaceutical industry
economic growth
Monitoring of established products
Developing and emerging countries
Improving communication amongst various
partners in pharmacovigilance.
MESSAGE
To achieve the ultimate goal of
pharmacovigilance i.e. rational and safe use
of drugs
Every person on earth needs to be involved
Let’s strive to make the world a safer place
to live where benefit-risk ratio of drug
therapy is in favor of the human race
Its time to join hands &
Share a common goal to deliver safe drugs to our
patients
