18
Q

Pharmacovigilance

A

MARC
medicine safety monitoring
“monitoring of the safety and marketed medicines and taking action to reduce risk and promote safe use, thereby protecting public health”
Note: as some adverse effects of medicines wont be immediately apparent when they come to the market, and only become apparent once tested on a larger group of people

19
Q

Goals of pharmacovigilance

A
  1. Previously unrecognised hazards or signals (are identified)
  2. Evaluate changes in risk and benefits
  3. Action taken to promote safer use of medications
  4. Health professionals to be provided with optimal information
20
Q

What drugs can often cause allergic reactions?

A

NSAIDs

21
Q

CARM reporting

A

What: Suspecting a ADR, dont have to have evidence (because if receive enough of these signals, begin to realise that this is a real and consistent adverse reaction)
Who: anyone, but ideally Health professions and Pharmaceutical companies
How: Record patient details and event details, yellow ward form, online, email, post, fax.

22
Q

Spontaneous Adverse Reaction reporting

A

Early warning of unrecognised possible hazards

  • Previously unknown ADRs
  • or a Change in the FREQ or SEVERity of a already known side effect
  • **Diagram: Health professionals –> Regulatory agency (Medsafe) and Pharmaceutical company
23
Q

Medsafe response

A
  1. Analyse data to determine if safety signal is real
  2. undertake a risk-benefit assessment –> assess if action is required (MARC)
  3. Safety concern is confirmed:
    - information provided to healthcare professions and consumers
    - warning changes
    - available to only restricted conditions who receive significant benefit
    More significant concern:
    - change in medicines legal status
    - ask pharmaceutical company to commission a clinical study
    - removal of medicine from market
24
Q

Medsafe monitoring safety issues

A

watch out for side effects
e.g. highlights safety concerns identified from reports of suspected adverse medicine reactions sent to CARM
Encourages further reports and increase in information gathering re potential safety signals

25
Q

Medsafe Post Marketing surveliance

A
  1. Pharmacovigilence
    - medicine safety monitoring
    - MARC
  2. Investigation and Enforcement activities
    - compliance w. Medicines Act 1981
    - illegal import
    - adulterated and counterfeit medicines
    - unapproved medicines
26
Q

Medicine Regulations in the future

A

NZ and AUS collaboration failure: ceased to establish a JTPR Joint Therapeutic Product Regulator

27
