Letrozole: What Is It?

Letrozole, marketed under the brand name Femara, is a medication primarily used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing estrogen levels in the body. This reduction is particularly beneficial for postmenopausal women with hormone receptor-positive breast cancer.

Letrozole’s mechanism of action involves inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens. By blocking this process, letrozole effectively lowers estrogen levels, thereby slowing the growth of certain types of breast tumors that require estrogen to grow.

Letrozole is primarily indicated for:

• Postmenopausal women with hormone receptor-positive breast cancer
• Adjuvant treatment following surgery
• Treatment of advanced breast cancer that has progressed after tamoxifen therapy

Dosage and Administration
