Letrozole - Product Introduction

Definition: Letrozole is a potent aromatase inhibitor used primarily in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It works by inhibiting the enzyme aromatase, which is responsible for converting androgens into estrogens, thereby reducing estrogen levels in the body.

Functions:

· Inhibits aromatase, reducing estrogen production in the body.

· Helps prevent the growth of estrogen-dependent breast cancer cells.

· Used as adjuvant therapy to reduce the risk of cancer recurrence.

· Can be used in the treatment of infertility in women with polycystic ovary syndrome (PCOS) by inducing ovulation.

Applications:

· Pharmaceutical Industry: Widely used in oncology for the treatment of breast cancer in postmenopausal women.

· Healthcare: Prescribed as a treatment for hormone-responsive breast cancer, particularly in adjuvant therapy after surgery or radiation.

· Fertility Treatment: Used off-label to treat ovulatory dysfunction in women with PCOS who are seeking to become pregnant.
