3. INTRODUCTION
• The number of chemicals, poisonous household products and
medicines on the Indian market it is increasing day by day
which can frequently increases the risk of misuse of these
products and leads to Greater incidence of intentional and
unintentional poisoning.

4. Poison information (PI)
Definition:
• It is a specialised area of drug information which includes information about
the toxic effects of chemicals and pesticides, hazardous material spills,
household products, overdose of therapeutic medicines, plants including
mushrooms, animal toxins from the bites of snakes, spiders and other
venomous creatures and Stings.
Functions:
• Provision of toxicological information and advise
• Management of poisoning cases
• Provision of laboratory analytical services
• Toxicovigilance activities
• Research education and training in the prevention &treatment of poisoning

5. EVOLUTION
• After the second world war a large number of medicines
and Chemicals were introduced into the market. consequent
to this globally there was a higher incidence of intentional
and unintentional poisoning especially in children.
Healthcare professionals had little knowledge about the
ingredients present in new products, in view of the
increasing incidence of poisoning and lack of awareness
among the public about the effects of poisoning the first
poison information services were established in Europe in
1940.

6. Indian scenario
• In India, As of 2010 there was only 4 WHO recognised centres
in India. in addition a few other centres established.
• the first national poison information Centre was established
in December 1994 At ‘All India Institute of Medical
Sciences’(AIIMS), New Delhi.
• The Other centres were subsequently established at national
institute of occupational health, Ahmedabad
• government General Hospital, Chennai and
• Amrita Institute of Medical Sciences and Research Cochin.

7. FUNCTIONS…..
1. Provision of information and advise:
• The main function of Poison information centre is to provide information
and advise concerning the diagnosis, treatment & prevention of poisoning, as
well as about the toxicity of chemicals and risks they pose.
• To provide information on toxic chemicals, including data on risks to the
environment and on safe levels in food & environmental media as well as in
the work place.
All information and advise should be adapted to the specific
circumstances of the suspected poisoning i.e. whether exposure to the poison
is acute or chronic, and the condition of the patient involved, taking into
consideration the type of enquiry and the enquirer’s technical understanding
of the poisoning. The information service must be available 24hrs a day,
seven days a week, throughout the year.

8. FUNCTIONS…..
2. Patient management:
It is necessary to confirm whether poisoning has actually occurred, to
ensure that the proper first-aid measures can be taken, and to assess what
type of treatment, if any, is required.
The centre exists to provide information, giving advise on the
different aspects of diagnosis and treatment that is appropriate to the
enquirer’s understanding level.
The close association between poison information services & poison
treatment services, facilitates the necessary updating and expansion of
information on the diagnosis and treatment of local poisoning cases,
encourages follow of patients & stimulates essential research on human
toxicology and patient management.

9. FUNCTIONS…..
3. Laboratory services:
A laboratory service for toxicological analysis and biomedical
investigations is essential for the diagnosis, assessment and treatment of
certain types of poisoning. It is especially important for clinical units treating
poisoned patients: without analytical data, many toxicological problems can’t
be accurately assessed.
Laboratory service can also determine the kinetics of the toxin,
particularly its absorption, distribution, metabolism & elimination.
Analytical facilities are also essential for research and for monitoring
populations at risk from exposure to toxic chemicals.
A laboratory should have adequate staff & equipment to carry out the
analysis that are essential in cases of poisoning with in the country or region.
It requires at least one trained analyst & one assistant, but larger numbers of
personnel will be needed as the range of techniques in use & the number of
analysis being performed increases.

10. FUNCTIONS…..
4. Teaching & training:
The centre with educational responsibilities will train the medical
practitioners & other professional health workers likely to encounter the
poisoning.
5. Toxicovigilence:
It is the active process of identifying and evaluating the toxic risks
existing in a community and evaluating the measures taken to reduce or
eliminate them.
The role of a centre in toxicovigilence is to alert the appropriate
health and other authorities so that the necessary preventive and regulatory
measures may be taken.

11. Drug information & Pharmacovigilence
• Poison information centers are automatically concerned with problems of
ADR and side effects.
• Poison information thus have the responsibility of contributing to
Pharmacovigilence in collaboration with other institutions established for
that purpose.
• Drug & poison information centre is one that provides information regarding
both drugs & poisons.
SULTAN UL ULOOM COLLEGE OF PHARMACY 11

12. Benefits
• It offers considerable direct health benefits by reducing morbidity &
mortality from poisoning
• Specific antidotes , therapeutic agents and medical equipment can be made
more easily available through coordination of stocks.
• Also help to prevent the unnecessary use of special antidotes and of
sophisticated and expensive treatments.
• Access to information and advise at poison information centers stimulate the
interest of local communities and makes them more committed to the
prevention of poisoning.
• Help in promoting the awareness of special requirements concerning the
control and regulation of chemicals.

13. Establishing a PIC
• A poison information centre should be available in every country irrespective
of its size or population.
Location:
• The centre should be located at a leading hospital with emergency &
intensive care services as well as the medical library and lab.
• It should be linked directly with the hospital department where poison
patients are treated.
• The lab facilities of such hospitals should allow toxicological analysis
• It should operate 24hrs a day all year round.
SULTAN UL ULOOM COLLEGE OF PHARMACY 13

14. Staff:
• PIC needs a multidisciplinary team of poison information
specialist lead by physicians with toxicological experience.
• The team may include physicians, nurses, analysts, pharmacists
veterinarians and other scientists from various fields including
biology, chemistry, medicine and pharmacology.
• A poison information specialist helps to prepare & provide
information & advise on preventing and dealing with poisoning.
• A poison information specialist should work under the
supervision of medical toxicologist.
• Minimum of 2 poison information specialists should be on duty
to answer calls.
SULTAN UL ULOOM COLLEGE OF PHARMACY 14

15. Equipment & facilities:
• Suitable office furniture & facilities for the storage of confidential data.
• Specific areas should arranged for answering telephone enquiries,
consultation with patients, preparation of documents, staff meetings and
secretarial and administrative work.
• Additional desk space is needed at centers using computer equipment and
on-line databases, air conditioning and humidity control may also be
necessary.
• PIC’s should their own libraries & facilities for handling and reproducing
documents.
• A fax machine is necessary which is recognized means of communicating
information rapidly among centers and hospitals during emergencies.
SULTAN UL ULOOM COLLEGE OF PHARMACY 15

16. ORGANIZATION & OPERATION
• The effective function of a poison information centre depends on the
availability of an adequate volume of evaluated data to furnish a basis for the
advise given.
• PIC’s should establish a mechanism for obtaining access to adequate data on
commercial products from manufacturers and should be regularly updated
&its confidentiality protected.
• Once a PIC becomes operational, i.e. able to offer an emergency response
service, it should function around the clock.
• The information handled by PIC relating to manufactured products and
patients, must be considered as confidential.
• Rapid identification of poisons or type of poison involved in an emergency is
one of the centre’s main task.
