[RegAffairs]API % Assay Calculation in Commercial Batch

Hello Everyone,

We are planning to take a Validation/Commercial Batch for a potent 
drug with a dosage of 0.125 mg per tablet.

Assay of the API to be used in the batch is 100.2%.

I've seen in other products where the % Assay of API is less than 100 
(lets say 98.8%), the total quantity of the API to be dispensed was 
calculated to attain 100% of the Label Claim. The result will be 
greater than the theoretical weight of the API required for the Batch.

In the PRESENT case where %Assay is Greater than 100% (LETS SAY 
101.0%), should the quantity of the API to be dispensed be calculated 
on 101.0% basis?In this case, the quantity of the API to be dispensed 
will be less than the theoretical quantity of API required for the 
batch.

In my opinion, even though the % Assay result is > 100% it should be 
considered as 100%.

Waiting for your inputs in this regard and correct me if I am wrong.
