The names and doses: Femara (letrozole) and Arimidex are both aromatase inhibitors that are taken by mouth once a day. They work by prevenitg fat cells from making estrogen, which lowers total estrogen in your body. We use them identically in practice.

Very little: Both of these drugs are aromatase inhibitors and are used to treat post-menopausal hormone-sensitive breast cancer patients. Their chemical structure is remarkably similar. No study has ever compared these two drugs "head-to-head", so it is hard to recommend one over the other. If one of my patient's side effects are so severe that they are contemplating stopping the med, i switch to another.
