Dear scopy,

❝ How about if its the other way? That is:

❝ If the dissolution values for the Comparator product were 32%, 63%, 88%, 91%, 95%, 96% and 97% respectively. And that of the Test product were 23%, 44%, 52%, 65%, 76%, 89% and 92% respectively.


Here also you have to calculate the f2 factor as your test drug didn't achieve a release of ≥85% at the time point 15 min..

both test and reference products dissolve 85 percent or more of the label amount of the drug in 15 minutes

❝ Want to know what USFDA, EMA and WHO recommends in the above case scenario.


❝ I actually did the calculation and got an f2 of 99.5. However the reason I wanted someone else to the calculation is to know the time points to use. I used time points of 5, 10, 15, 20, 25, 30 mins because the comparator product was able to achieve >85% dissolution at 30 mins. Wanted to know if I'm right.


Now comes the difference in the GL'S, in this case (your second case scenario) as Helmut mentioned above:
