Q

Why is post market control important

A

ongoing safety and performance monitoring is important to ensure patient and public safety after device is released on the market

  1. inherent risk throughout the medical device life cycle, even for low risks ones,
  2. limitation of pre-market registration controls, and to
  3. enable timely intervention to safeguard public health.

25
Types of registration in conformity assessment
- Registration of devices | - Registration of persons
26
Mandatory requirements in Health Products Act
- Control supply chain via dealers & establishments Dealer Licensing - Legislation identify and define the joint responsibility of importers, authorised representatives and distributors - All of them are governed by the legislation and must comply - Responsibility period is for the entire lifetime of the device
27
Premarket control of medical device regulation (2 prong)
Dealer Licensing - Manufacturer's License - Importer's License - Wholesaler's License Product Registration - Registered medical device for supply in
28
Dealer's Control
GDPMDS SS620:2016 is a requirement for all licensed local importers and wholesalers (auditable) * ISO13485 for Manufacturers already covers the scope for GDPMDS
29
Good Distribution Practice for Medical Devices
- mandatory to importers & wholesaler - ensures quality distribution system - ensure a system to comply with post-market requirements, including AE reporting and FSCA
30
Distributor Activities
procurement, storage, distribution of medical devices in large quantities in accordance with legislation
31
Product Registration
- Phased in approach - Higher risk C & D registered before A & B - Authorised Representative (AR) responsible (does not need GDPMDS and are not top management)
32
How to register product
Singapore uses the CSDT – common submission dossier template for submission
33
Pharmaceutical Manufacturing
- Milling - Drying - Compresison - Coating
34
Drug features
- Consists of therapeutics and excipients combined in a delivery system - deliver drugs at certain rate determines drug success - Active Pharmaceutical Ingredients (API): active ingredients in medicine
35
Good Manufacturing Processes (GMP) of drugs
* record keeping * personnel qualifications * sanitation * cleanliness * equipment verification * process validation * complaint handling
36
Sources of risks from drug products
- Avoidable & unavoidable known side effects - Medication errors - Product quality defects
37
Product/ Process development paradigm
- Manufacturing - Process development & scale up - Formulation - Drug synthesis
38
Dosage Forms
- Tablet/ Capsules - Injectables - Inhalants - Transdermal implants and products
39
Oral dosage forms
Tablets - Lozenges - Chewable tablets - Effervescent tablets - Multi-layer tablets - Modified release Capsule - Hard gelatin - Soft gelatin Powder
40
Inhaled dosage forms
Aerosols - Metered-dose inhalers - Dry powder inhalers
41
Stages of pharmaceutical manufacturing
1. Starting materials (chemicals) 2. API 3. Finished product (includes exepients) 4. Primary packaging 5. Secondary packaging
42
What are excipients
- an inert substance added to the drug to give suitable consistency or definite form to the drug - pharmaceutical necessity/ aid
43
Types of excipients
- Antioxidants - Ointment base *for compounding of the pharmaceutical dosage forms
44
Antioxidant
- inhibits oxidation - added to prevent deterioration via oxidation etc. - the development of rancidity in oils and fats - inactivation of some medicinal in the environment of their dosage form Provides H+ electron to free radical to terminate chain reaction
45
Excipient list
Fillers: increases weight and size of final dosage form Binders: promote particle aggregation Disintegrants: promote breakdown of aggregates Flow aids: reduce interaction between particles Lubricants: reduces interaction between particles and surfaces of processing equipment Surfactants: promotes wetting Modified release agents: influences the release of active
46
Solid Dosage Processing
Dosage forms - Quality factors Excipients Particle properties Processing routes Unit operations
47
Quality factors for solid dosage forms
Functional quality factors - Disintegrates to desired size quickly - Dissolve and absorbed in the GI tract at a pre-determined rate Physical quality factors - withstand processing, packaging, transportation, dispensing or handling - Surface must be free of defects - Must be stable under anticipated environmental conditions - consistent weight & composition for each pill Sensorial quality factors - Easy and pleasant to swallow
48
