How to ensure the uniformity of API coatin on tablet?
by ensuring proper spray rate.
spray contain active so how to know that proper API is deposited on tab?
then I have no idea
proper monitoring of weight gaint after specified time intervals eg 30 min is performed.
and weight gain must be in validation data range
Is data need to be exact or any deviation range accepted?
+,- range is available bcz can not precise to be 100 % aftr 30 min.
but at the end of coating weight should be within limits
Yes ,weight gain is the right method
