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?

to cure diseases of which they know less,
in human beings of whom they know nothing.    Voltaire
