Safety
Will you allow the use of a drug for yourself or your
loved one which is suspicious in terms of safety?
![Page 14: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/14.jpg)
Safety
Can you catch presence of any toxic substance by testing
![Page 15: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/15.jpg)
Efficacy
The drug is overheated in the dryer. What do you think?
Should it go to the market
![Page 16: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/16.jpg)
Cleaning
An equipment is cleaned but not properly cleaned after
manufacturing of a male hormone. Time is not available
and you have to manufacture female hormone in the
same equipment.
What decision you think appropriate?
![Page 17: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/17.jpg)
Consistency
Can you catch the variation in consistency
by product testing?
![Page 18: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/18.jpg)
HVAC
Can you list what is harm, if we do not supply HVAC in
a manufacturing facility?
![Page 19: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/19.jpg)
Documentation
Why do we rely on document only and do not rely on a
trustworthy person?
![Page 20: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/20.jpg)
Validation
Instrument is not a human being. Why do we require
exercise to develop trust on equipment performance?
![Page 21: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/21.jpg)
Process Parameters
…….. Dry at 15 to 20 minutes.
Why do not write dry up to 2% moisture level in batch
instructions?
![Page 22: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/22.jpg)
Quality Attributes
What would be the harm if a tablet is cracked?
Why it is not acceptable?
![Page 23: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/23.jpg)

Because
Drugs are public good and not simply just another commodity:
first for their high social value, and then because consumers and
prescribers are unable to assess their quality, safety and efficacy.
Quality cannot be observed by every one and/or by naked eye.
Quality cannot be tested in a laboratory but has to be built in to
the product
![Page 36: OARO 11 Feb 2017](https://reader031.fdocuments.net/reader031/viewer/2022030116/58ac11ec1a28ab33178b5bcf/html5/thumbnails/36.jpg)

is not simple but so complex

Ways to keep align with modernization
Time wastage in quality documentation & administrative procedures?
Do you have adequate trained personnel in the maintenance unit?
Are adequate SOPs and maintenance protocols in place?
Analyze your number of defect rates, deviations?

Take Home Message
Keep an eye on ways
of Improvement
Always stay on the ball
regarding technology
Continuously adapt to
the changes
Implement improvement procedures,
perform risk assessment, analysis, set up
actions & document efforts
Keep abreast of new technologies &
processes. Work with your supplier to try to
improve your machinery on the shop floor
Try to implement a culture of quality and
improvement. The only constant thing is
change
