Hi Amira!

» […] if the BE study for amoxicillin/clavulanic acid is done under fast or fed conditions with references please??

Please do you homework first (see also this post #3).

The FDA requires two studies (fasting & fed). IMHO, that’s not a good approach because you might face a lot of nasty GI-related AEs in fasting state.

IMHO, the EMA’s GL is better (Section 4.1.1):

For products where the SmPC recommends intake of the reference medicinal product only in fed state, the bioequivalence study should generally be conducted under fed conditions.

The SmPC:

Augmentin should be administered with a meal to minimise potential gastrointestinal intolerance.


In our studies we didn’t serve a high-fat high-calory meal but a light breakfast as a compromise (since fasting is considered more discriminatory).

I believe there is no philosophical high-road in science,
with epistemological signposts. No, we are in a jungle
and find our way by trial and error,
building our road behind us as we proceed.    Max Born
