Sir which Therapeutic value to be considered for calculation of MACO....? Maximum TDD or minimum If menttion 250 mg twice a day, How much to be considered? If 10 mg/ kg mentioned, how much to be considered? Please suggest.
I suggest, you can go through this video. You will get all information. ruclips.net/video/zA5xsWR9IU8/видео.html Further I suggest you can go through the another cleaning validation webinar with practical approach. You will get all the information about your questions.

The failure need to be investigated. If you are handling through deviation, the analytical error also need to be investigated and evaluated. I personally recommend to investigate as per OOS procedure.
Hi sir please clarify whether nitrosamines can be eliminated in cleaning during reaction in vessel?? Is it possible??or else only downstream process mechanism of chemistry can control nitrosamines
Hi, I need to understand the process. I suggest, you need to take steps to avoid the generation of this impurites. For further details, please go through the FDA advise. www.fda.gov/media/122643/download
Pls tell me any reference guidelines available for clean and unclean hold period of equipment and accessories used for manufactring of OSD formulation.
As per EU guide- "The influence of the time between manufacture and cleaning and the time between cleaning and use should be taken into account to define dirty and clean hold times for the cleaning process". I need to check FDA requirement. Hope, this will solve your purpose.
During equipment matrix API Contact equipment we have select or all the equipment used for mfg process. We are using tray dryer for excipients drying and no API is used for tray dryer, so we have to select tray dryer in equipment matrix or not?
We have to perform cleaning valiadation for the equipments which are used for manufacturing of the multiple products. Tray drier is not used for manufacturing. Active ingradient or colour is not handled. Hence, we should not consider in equipment train. Otherwise, the total equipment contact surface area will be very high if we go on considering all equipments. This may result in impractical MACO limit. Hope, this clear your doubt.
Campaign cleaning should be based on the nature of the product and campaign length. It should be based on period and number of batches whichever is lower.
How to justify campaign cleaning , if I am doing periodic cleaning after every ten batches...I want to give rational for ten batches , so how to justify it's betterly.
@@dharmeshrabadiya5624 Based on the business requirement and also nature of the product you can decide the campaign length. That you need to validate and justify that no impact.
@@hitendrakumarshah3718 Thank you Sir . Quality evaluation done for 1-10 batches series and found complies results, hence there is no impact . I think it is ok.
Why you need this information. Please focus on compliance and practical implementation approach. Becuase, in Pharma we always follow cGMP and also benchmarking.
Its really nice question. But, it can not be answered in straight way without understanding the details. Request you to put more details about this case. So that, I will able to evaluate and revert you correctly.
Dear sir, I have Question, if batch size change can i do cleaning validation ? (we have 1 kg, 2 kg & 3 kg batch sizes) if product Strength Change can i do cleaning validation ? (we have 5 mg, 10 mg, 25 mg, 50 mg Strengths) How many cleaning validation Runs shall be performed ? { 3 Runs for each strength (or) 1 Run for each strength ? & 3 runs for each Batch size ? or 1 Run for Each batch ? ) Contact Equipment's are not changing This is NEW PRODUCT INTRODUCTION . How can i establish Cleaning validation ? what is the cleaning validation approach please provide me Reference Guidelines. Regards, Goutham
Hi, I can evaluate to identify the worst case product among all the products. You have to consider one product batch size as minimum batch size below which if you go , again you need to evaluate worst case as, the limit will change after change in smallest batch size. Then, you can perform 3 consecutive runs of cleaning validation on worst case product and complete the study. Hope, this is clear to you.
The nitrosamines are impurities of drug substance generated during manufacturing, processing of drug substances. These impurities are potent genotoxic carcinogens. Hence, if it is generated during manufacturing, efforts, should be made to avoid from going to next batches. It depends on the manufacturing process that you are dealing with. Please go through in detail- the FDA general advise. www.fda.gov/media/122643/download
There is no guideline states the number of batches to be considered for cleaning validation. However, for process validation, EU clearly suggest to have minimum 3 consecutive batches . So, as a routine practice, for cleaning validation also 3 batches are selected (considering it as process validation. Only the difference here is, the cleaning process will be validated instead of manufacturing process). Hope, it is clear to you.

Thanks for your valuable comments I am totally agreeed with your suggestions for unclean study since there is always chances of increase in bioburden in uncleaned equipment however why we can't go beyond 7 days frequency for clean equipment based on validation study and risk assessment. Is there any regulatoy requirement for such validation study upto 7 days only. Please advise
@@samvdio7513 The guide doesnt state about actual period for the study. But, considering the lowest practical scenario we should consider. 7 days will be too long for keeping any equipment in dirty condition. QRM should not be followed to address wrong practices. Hope, you got the answer.
Shah sahab, you are giving good information to audience. Appreciate your efforts.
Thank you so much
Thanks Sir Very nice session. Particularly the question answer session was very useful
Thanks. Please keep learning
Hi sir good morning
I watched your video on 19-12-2020

Very insightful lecture.. Thank you sir for your great help
Thank you for your kind comment.
Thanks for valuable session.
Qus- sir how to clean the swab area after swabing.
You need to use same vehicle to clean the swab surface area. It should be specified in the SOP.
Which sampling method is best to start first I.e rinse or swab
Both sampling methods are having their own positive and negative points. You can make use of both methods.
Sir what should be the acceptance criteria for degradation in DEHT?

The failure need to be investigated. If you are handling through deviation, the analytical error also need to be investigated and evaluated. I personally recommend to investigate as per OOS procedure.

Sir what is soil condition, in cleaning validation study?
It reflects the information about DEHT(Dirty Equipment Hold Time) study.

Its really nice question. But, it can not be answered in straight way without understanding the details. Request you to put more details about this case. So that, I will able to evaluate and revert you correctly.
Where we will take recovery study values in cleaning validatiin
You can consider recovery factor either in final calculation or in QC where they are calculating and arriving on results.
Is it necessary for making cross change over matrix
It depends on scenario. This question needs to evaluate in detail and generic answer can not be given to this question.
Sir
If MACO calculated by help of largest equipment surface area then no need for cross change over matrix required
Is it right or wrong?

So, as a routine practice, for cleaning validation also 3 batches are selected (considering it as process validation. Only the difference here is, the cleaning process will be validated instead of manufacturing process). Hope, it is clear to you.
For statistical evaluation minimum 03 batches are required. Hence at least 03 batches are considered for cleaning and well as process validation.
