I am looking for information and solutions to preventing foreign tablet issues in our manufacturing plant. We do not have dedicated tableting or packaging lines and despite efforts in cleanings, inspections and engineering fixes we still have issues. Any comments and direction would be appreciated.

Can I know what a foreign tablet is? Do you mean the traces of previous batch? This is more of a discipline. Make a checklist of places where you had problems so far and concentrate on them.

 
If you are saying that you still find tablets from another product line (cross contamination) I would say that you have a very, very serious problem.
Please specify more for us to understand.
 
Thank you for foreign tablet suggestions. Foreign tablets are cross contamination from previous products/dosages. These happen mostly on our packaging lines( we do not have dedicated product lines)and change products frequently on lines. We are aware of seriousness and continue to list and generate engineering fixes to "harbor" spots on our equipment. We are also focusing on the cleaning disipline.

I am looking for any other suggestions that World Class Pharmaceutical manufacturers use to address cleaning, inspection, detection to prevent this foreign tablet cross contamination.
 
In general, you focused the points to adress:
From an engineering point of view, to not allow "dead areas" where tablets or tablet chips can stay from one product to the other.
Of course you will not be able to avoid all these dead areas and that where the procedures, verification and discipline come in. You already know where are these areas, if can be enginnered to close it, do itr, the others you will have to rely on the persons.

It is always usefull to have a packaging responsible that you can draw the attention regarding these points.

In a multiproduct pharama that I worked our packaging machines were also not dedicated. Each of the blister machine+cartoning machine had a person that was the ultimate responsible to have teh line working and specially to assure the cleaningness.

One source of contamination that persons usually forget if the staff itself. During the packaging operation do you have staff that is not directly related with teh operation hanging around?
Finish with it and limit acess to those areas. If you limit the acess then you can have persons responsible for the area that you can train.

Other good thing to do is to give some general training to the staff regarding this problem. If you still have it is because the line staff doesn't take so much attention to it.
Go to the internet (and FDA website) and take examples of Forms 483 that pointed out cross contamination issues. Then use also some examples of labs that had to close or saw their revenue strongly affected because of FDA audits and translate that to your company. Eventually you can also find cases of civil suits or call of products because cross contamination issues.
If you deliver the message that "This issue is against all GMP, FDA, ICH regulation, someday authorities will close our door and everybody goes home.",then they might be attentive to it.
Try to put everything in terms of money (lost business, lay-offs, etc. ) and persons will easily understand.

And if the older ones come with the same old story "We have been doing this for 30 years and up to now there was never a problem" tell them the story of Able Labs.
Sorry for the long post.

 
MedicineEng:
Thank you for your time and interest in our situation. Your input is valued.
 
If you don't have separate packing lines, try to have separate accessories, atleast. The OSD facility, I worked with earlier, has got separate in process containers and bins for different products. We used to change BOPP films from product to product. Try to provide guides on either side of the tracks so that unfilled tablets can be collected on the track. Don't deblister the tablets near packing lines.

Try to maintain a list of places where you had problems earlier and put one person to inspect the particular locations before starting production. Go on adding up new locations whenever problems are found. Make the inspector accountable for cross contamination and punish for a repeated mistake.
