Femara vs Arimidex

[Barbara2]

I believe I read somewhere that Femara demonstrates a greater benefit in women at increased risk of breast cancer recurrence than the other aromatase inhibitors. But it seems that the dosage was higher in the Femara than the 1 mg usually used for Arimidex.

Has anyone changed from Arimidex to Femara because it may be better?

I've also read that there are upcoming trials that will put these 2 drugs head to head.

Thanks!
