Switching to AROMASIN showed no significant survival benefit over tamoxifen therapy.

AROMASIN® (exemestane tablets) is a prescription medicine for the adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer. Treatment with AROMASIN should begin after 2 to 3 years of tamoxifen, at which time tamoxifen should be discontinued. Treatment with AROMASIN should continue for 2 to 3 years (until the completion of a total of 5 years of adjuvant treatment with tamoxifen and AROMASIN).
