What do the numbers in the “Recommended Sampling Times” column mean?
The “Recommended Sampling Times” field specifies the times recommended for taking dissolution samples for a particular drug product to generate a dissolution profile. The times are given in minutes, unless the word “hours” appears after a number. FDA generally recommends that by the last sampling time, at least 70-85% (Q) of the labeled content of the active drug should be dissolved, depending upon the specific drug product.
