Pharmacovigilance:• Pharmacovigilance (PV) also called as
drug safety. Pharmakon (in Greek) :Drug Vigilare (in Latin) : to keep
watch
• It is the umbrella word for ADR’s monitoring.
Definition• Accon to WHO “It is pharmacological
science relating to the detection , assessment, understanding and prevention of adverse effects”
AIM• To improve patient care and safety. • To contribute to the assessment of benefit,
harm ,effectiveness and risk of medicines.• To promote education and clinical training. • To promote rational and safe use of
medicines.
Need of Pharmacovigilance
• Humanitarian Concern.• Safe use of medicines.• ADR’s are expensive.• Promoting rational use of
medicines.• Ensuring public confidence.
Reason :1
Humanitarian concern:Insufficient evidence of safety from clinicaltrials, Animal experiments & Phase 1 – 3
studiesprior to marketing authorization.
Reason:2
Medicines are supposed to save lives: Dying from a disease is sometimes unavoidable; dying from a medicine is unacceptable.
Reason :3ADRs are expensive !! ADR’s as cause of admission to hospital; analysis of 18820 patients.•6.5% admission due to ADR’s•ADR related cost to the country exceeds the cost of medications themselves.
Reason: 4
Promoting rational use of medicines and adherence Reason :
Reason:5 & 6
5) Ensuring public confidence Reason
6) Ethics :To know of something that is harmful to another person who does not know, and not telling, is unethical
Function:
• Receive and manage ADR data.• Develop tools. • Analyse. • Signal detection :Identification of
previously unknown drug reactions.• Communicate.
Pharmacovigilance system
• Records medication related errors• Analyses those errors • Implements interventions• Promotes patient safety• Prevent 'preventable errors‘
Preventable Errors
• Handwriting of prescriptions• Drug interactions.• Similar-sounding and look-alike names and
packages of medication.• Level of stress on workplace.• Unclear records in information system• Disruptions in information availability and flow
How to prevent errors• Introduction of advanced medical
information systems– Electronic Health Record (EHR) – Automatic checks for dose, interactions,
allergies, resistance.– Personalized prescription (on base of
pharmacogenetic data).• Analyze all errors, research what enabled
them. • Try to design uncomplicated processes.

Collaboration with WHO-UMC
• Collaboration with World Health Organization-Uppsala Monitoring Centre (UMC) WHO and UMC work with and provide technical support to more than 94 countries worldwide. The long term objective of the Pvpi is to establish a ‘ Centre of Excellence ’ for Pharmacovigilance in India. To achieve this objective, the Pvpi National Coordinating Centre will collaborate with the WHO Collaborating Centre - Uppsala Monitoring Centre (UMC) based in Sweden.
Partners in Pharmacovigilance:
• The pharmaceutical industry
• Regulatory authorities
• WHO collaborating centre for international drug monitoring
• CIOMS(Council for International Organization of Medical Sciences )
Role of clinical pharmacist in Pharmacovigilance:
• Provide medical history.• Create database.• Monitoring patient.• Improving patient compliance • Documentation of case for future reference.• Follow up of patients to assess outcomes.• Encouraging health professional and patients.• Patient and health care professional education.
Drugs Banned
Four Drugs banned in all countries but not in india
Special Cases for PharmacovigilanceSome groups of medicinal products are not required
todocument their safety – natural medicines,
homeopathicPreparations.1. Natural (herbal) medicines :• Exact composition is often not known, efficacy nor
safety is usually not documented• 37 ADR reports in Australia related to Echinacea
use in allergy.
Special Cases for Pharmacovigilance2. Homeopathic preparations:• Zycam Cold Remedy case – unusual dilution
resulted in permanent loss of smell in several subjects and 340 filed.
• Content of alcohol in some preparations for children is higher than allowed in allopathic medicines.
Summary & ConclusionTo minimize the harm, medicines should
be good:
In all, Pharmacovigilance will promote: • Systematic and rational use of medicines.• Boost confidence for safety.
