Used primarily in the treatment of hormone-dependent breast cancer in postmenopausal women. It functions as an aromatase inhibitor, effectively reducing estrogen production by blocking the conversion of androgens to estrogens. This helps in slowing down or stopping the growth of cancer cells that rely on estrogen. Additionally, it is utilized in veterinary medicine for managing estrogen-dependent conditions in animals. Research studies also employ it to investigate the role of estrogen in various physiological and pathological processes.
