Hi ceylan,

» For PK bioequivalence, 90% confidence interval is ok both for US and EMA.
»
» For PD bioequivalence, I want to ask about the confidence interval for US and EMA?
» Is it 90% CI for US and 95% CI for EMA?
»
» And in what circumstances, 90 % CI and / or 95 % CI are being used?

I think the question is a little too general.
Sometimes regulators want a 95% CI other times they want a 90% CI.
Here's a case of a 95% CI being used.

Whatever you do, if you need PD I recommend to go for a scientific advice. Ask about 90% vs 95% if there is nothing written in a guideline. Don't make assumptions and don't take chances.

Pass or fail!
