Hi Scopy,

» […] a situation where a test product is rapidly dissolving (>85% in 30 mins) while the comparator product is very rapidly dissolving (>85% in 15 mins) and vice versa. Is f2 calculation necessary? If it is, which time points will be used?

Tricky. ƒ2 is generally not required if product(s!) release ≥85% in all three media. In the calculation of ƒ2 the devil is in the details. There are different restrictions on samples after 85% release:Hence, bad luck for the EMA. For the FDA and the WHO, it depends.

BTW, what is an FFP?
