Small Scale Manufacturing - Tim Sizer Flashcards
Why are personalised/bespoke medicines so beneficial to patients?
As it is more specific to the patient and their disease, so clincal outcomes are greater…with less side effects
Especially for those that have very different genetics for certain drugs (eg, fast/slow metabolisers)
What are the 3 conditions that must be met for an unlicenced drug to be used?
In reponse to a bona fide unsolicited order
Formulated in accoradance with the specification of a doctor, dentist of supplementary prescriber
For use by individual patients with the prescribers responsibility
The unlicenced medication must also have data to suggest it is safe and effective….and that any licenced drug in inappropriate

As long as it occurs in a registered pharmacy and under the supervision of a pharmacist
What’s the difference between ISO 9000 and ICH Q10?
ISO 9000 –> A management system to direct and control an organisation with regard to quality
- Focusses on continuous improvement
ICH Q10 –> A combination of GMP and ISO 9000, with key objectives and enablers
- Focus on a product life cycler approach
What is Good Manufacturing Practice (GMP)?
Part of Pharmaceutical quality assurance (QA) which ensures that products are consistently produced and controlled to the quality standards appropriate to their intended use and the product specification
Concerns both production and quality control
Define Quality
In the pharmaceutical sense
The degree of fitness for purpose
What is Quality Control?
The part of GMP that is concerned with sampling, specifications and testing
Must be done to ensure the product is of good enough quality to be released
What are the 5 possible limitations of PQS?
Cost of quality –> Is it fit for purpose?
Documentation –> Can be overcomplicated
Processess –> Can be too complex (to ensure you meet regulations)
Detail –> May be in excess or be insufficient
Knowledge Management –> Not enough people may understand the reasoning behind the PQS
What are the 6 sources of contamination in an aseptics suite?
People
Workspace
Starting materials and consumables
Storage
Aseptic process
Adminstation of the product
How should cleaning and disinfecting be done in a clean room?
Use a disinfectant rota –> To prevent resistance build up
Use in-use dilution disinfectants (must be used right away) in grade A/B areas
They must also be sterile disinfectants in grade A/B areas
At what temperature should starting materials (in a clean room) be stored at?
2-8 degrees when appropriate
In step 1 of transfer disinfection, what type of disinfectant would be used?
An alcohol spray CONTAINING a sporacide
What are the alert and action levels of contamination for all tests?

Action –> 5% outside

5 years
What is Good Distribution Practise (GDP)?
Part of quality assurance that ensures that products are consistently stored, transported and handled appropriately under suitable conditions
Why are bathrooms and kitchens generally a bad place to keep medication?
Temperature cycling
Moisture
Heat
What are the 6 risks to pharmaceutical drug quality?
Manufacture
Microbiological
Biological (eg, pest control)
Chemical
Temperature
Malicious Intent (human things done on purpose to harm)
When can the Arrhenius Equation be used to see if a drug can be kept (or should be thrown out) after undergoing thermal stress?
For room temeprature drugs only!
Not fridge lines
What types of medicines are likely to be counterfeit?
High value lifestyle drugs (eg, viagra)
High value lines
High volume, mid priced drugs (eg, Lipitor)
