No: Tamoxifen belongs to a class of drugs called selective estrogen receptor modulators (serms). It works by blocking the binding of estrogen to estrogen receptors, thus disabling hormone-sensitive breast cancer cells. Aromatase inhibitors block the conversion of androgens to estrogens, effectively removing estrogen from the body (in postmenopausal women).

Similar: The mechanism of action (the way they work) is different. They essentially act as anti-estrogens.
