Pharmacovigellence Flashcards
Definition of pharmacovigilance?
Pharmacovigilance (PV) is defined as the science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug-related problem.
What is risk management plan?
RMP aims to identify, characterise prevent minimise risk of med
- identified what info is missing and what studies are needed to fill gaps
- continuously updated throughout life of med
Risk Minimisation
- risk severity or frequency
- tools such as SPC, PIL, labelling, packaging legal status
- controlled access programmes: requirements that need to be fulfilled before rx, like pregnancy prevention and valproate
VigiBase
computerised pharmacovigilance systemwide which info is recorded; purpose to provide evidence from which potential med safety hazards can be detected
-Eudravigilance- eu system wide, all members report to
MHRA
- Monitors the everyday use of medicines to identify previously unrecognised effects or changes in pattern of adverse effects
- Assesses the risks and benefits of medicines to determine what action is needed to improve their safe use
- Provides information to healthcare professionals and patients to optimise safe and effective use of medicines
- Monitors the impact of any action taken
What can you report using yellow card?
- Side effects (or ADRs) to a medicine, vaccine, herbal or homeopathic remedy
- Medical device adverse incidents
- Defective medicines (not of an acceptable quality)
- Counterfeit or fake medicines or medical devices
- Safety concerns for e-cigarettes or their refill containers (e-liquids)
Report Illicit Drug Reactions (RIDR)
-The MHRA and PHE have launched a scheme for reporting the effects of new psychoactive substances (NPS) and other illicit drugs
How to identify ADRS
- Patients may tell you about symptoms they have experienced since taking a new medicine
- Linking a sign or symptom to either current or previous therapy (can include OTC and unlicensed herbal remedies)
Be also alert to:
- abnormal clinical measurements (eg temperature, pulse, BP…) while on drug therapy
- abnormal laboratory results while on drug therapy
- if new drug therapy is started which may be used to treat the symptoms of an ADR
- listening to the patient’s own concerns regarding drug therapy
- considering the opinion of a parent if concerning a child
Children
react differently to medicines the pharmacodynamics and pharmacokinetics of a medicine may be very different when compared with adults
-many drugs which are routinely used to treat children are not extensively tested in children for their use; many used ‘off-label’
drugs may affect the way a child grows and develops or may cause delayed ADRs which do not occur in adults
-available formulations may not allow precise dosing in children or may contain excipients that should not be used such as alcohol
-the nature and course of illnesses and suspected ADRs may differ between adults and children
over 65
-because of changes in pharmacokinetics and pharmacodynamics

Black triangle Products
New drugs, biologicals and vaccines are being intensively monitored to confirm their risk/benefit profile (EU wide) = additional monitoring scheme (black triangle)
They also cover:
new combinations of drugs
new routes of administration for established drugs
established drugs with significant new indications
