Lecture 13: Medicine Regulations in NZ Flashcards
(40 cards)
MOH
Medsafe: MAAC, MCC, MARC (– CARM) and MRC
Pharmac (PTAC, CAC) –> Pharmaceutical schedule
- pharmac has global and general funding
Regulation of medicine
Medsafe:
“Medsafe’s mission is to enhance the health of NZ by REGULATING MEDICINES and MEDICAL DEVICES to maximise safety and benefit”
Medsafe is also responsible for administering the Medicines act of 1981 and Regulations 1984
Roles of Medsafe
- MAAC (assessment advisory com.) –> consent to market (approvals)
- MCC (classification com.) –> classification of medicines and how medicines become available
- MARC (adverse reaction com.) regulation and safety
- Education and information
- Quality and safety of manufacturing
What products does Medsafe regulate?
- Medicines (pharmacologic effect and used in humans primarily for a therapeutic purpose)
- Medical devices ( products which exert their therapeutic effect via physical rather than physiological means)
- Related products (throat lozenges, contact solution, some toothpastes)
Therapeutic purpose of Medsafe medicine and medical devices
includes treatment diagnosis and prevention of disease or the modification of a physiological function
- includes cleaning, soaking or lubricating contact lenses, effecting contraception or inducing anaethesia
- the claim that this product treats a certain conditio
What doesn’t Medsafe regulate
Complementary and alternative medicines (no therapeutic purpose)
Dietary supplements
Supplemented foods
Cosmetics
- these have no legal constraints
- difference b/w supplements and medications can be v. subtle e.g Folic acid (for reducing risk of spinabifida and neural tube defects) 800mg= prescription, but <500g is a supplement
What determines whether a product is a medicine, dietary supplement, food or cosmetic?
- Ingredients
- Intended use
- How it is marketed
Natural therapists Special provisions
Can manufacture, pack, label, sell by retail, or supply certain medicines (“general sale medicines” which arent regulated by med safe)
providing they’re supplied to an individual Following a consultation with a practitioner
Cant include prescription, restricted or pharmacy only medicine
- cannot shelve
- cannot already be a prescription medication (i.e. cannot repackage codeine or thyroxine)
Legislation for supplements
Natural health and supplementary products bill
- new regulatory regime, separate from food and medicines
Ensures that natural health and supplementary products are:
- safe to use
- have true health claims
- are made with and contain substances which the label identified
What supplements are exempt from the Natural health and supplementary products bill?
products which are made by a practitioner for an individual patient
Note: not exempt if sold over the countre
How does Med safe regulate medicine availability?
- PRE-market approval (MAAC)
- safety, quality and efficacy (after phase 3)
- supply chain - Control of access to medicines
- medicines classification: prescription, restricted, pharmacy only, general sales - MCC
- Considerations
Premarketing approval of a drug
New medicines need MOH consent
Changed medicines need consent from Director General of health
MAAC: gives advice to MOH on the benefits and risk of new medicines
MAAC
Medicines Assessment Advisory committee
- advices MOH on risks and benefits of New medicines
MCC
recommends classification of drugs to be - prescription medicines - restricted medication - pharmacy only medications under this act
What are some considerations which are thought about during a drugs pre-marketing approval?
policy convenience therapeutic index toxicity and abuse potential risks of inappropriate use risk of communal harm e.g. paracetamol is classified as relatively easy access as has a wide therapeutic index and doesnt tend to be abused
Unapproved/Unregistered medicines
medicines w/o MOH consent for sale, distribution of marketing
Can you prescribe an unapproved medicine?
- Section 29 of Medicines Act: allows sale or supply of unapproved medicines (have trailed and proved to be effective but arent registered.
- Section 25 of Medicines Act: allows use of unapproved medicines
- but patient cannot bring it in themselves and give it to people
Pharmacovigilance
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
Goals of pharmacovigilance
- Previously unrecognised hazards or signals (are identified)
- Evaluate changes in risk and benefits
- Action taken to promote safer use of medications
- Health professionals to be provided with optimal information
What drugs can often cause allergic reactions?
NSAIDs
CARM reporting
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.
Spontaneous Adverse Reaction reporting
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
Medsafe response
- Analyse data to determine if safety signal is real
- undertake a risk-benefit assessment –> assess if action is required (MARC)
- 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
Medsafe monitoring safety issues
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
