Dear Dr Babu,

Greetings !!

Hope your intented submission is not US as you have to follow OGD while for EU, 90 % BE should be on Ezetimibe (unconjugated) and not on total.

Ezetimibe is primarily metabolized in the small intestine and liver via glucuronide conjugation and produce congugated ezetimibe. (So total includes = Conjugated + Nonconjugated)

As it is a metabolic product, glucoronide formation might be different in individual subjects.

Moreover EU regualtory remains silent about measuring the metabolites.

So you can measure both(eze unconjugated & total), but perform BE only on Unconjugated.
