What does it do?

Letrozole is an antineoplastic agent belonging to the aromatase inhibitor class, primarily used for the treatment of breast cancer in postmenopausal women. This ingredient is used to reduce estrogen production in the body to inhibit the growth of cancer cells.

Letrozole blocks the process of estrogen production by inhibiting the enzyme aromatase. When estrogen levels are reduced, the proliferation of hormone-dependent breast cancer cells is suppressed, which can slow the progression of cancer.
