Mechanism of action

Aromatase inhibitors like Letrozole and Anastrozole work by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogens. By blocking this enzyme, they reduce estrogen levels in the body. Tamoxifen, on the other hand, binds to estrogen receptors in breast tissue, blocking the action of estrogen and thereby inhibiting the growth of estrogen receptor-positive breast cancer cells.
