Dear Anu,

there is no simple (or complicated) analytical way to calculate power or estimate the sample size for RSABE due to the complex conditions and requirements for the described methods (FDA or EMA) .

The only way known at moment is via simulations.
Have a look into the paper:
Laszlo Tothfalusi and Laszlo Endrenyi
"Sample Sizes for Designing Bioequivalence Studies for Highly Variable Drugs"
J Pharm Pharmaceut Sci (www.cspsCanada.org) 15(1) 73 - 84, 2011

Can be accessed online.

See also this thread here in the forum.

Hope this helps.
