Does aromasin kill aromatase enzymes currently bound by arimidex?

I was taking arimidex for high estradiol, and it was keeping it in check well. I'm switching to aromasin.

I know people there will be people who advise against switching. I've done the research and am making the switch and would rather not go in details about that.

Will aromasin only kill active aromatase enzymes, or will it also kill those that arimidex is currently binding?
