Understanding Letrozole: What Is It?

Letrozole 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 decreasing the amount of estrogen produced in the body. This is particularly beneficial for treating hormone receptor-positive breast cancers.

How Does Letrozole Work?

Letrozole functions by inhibiting the aromatase enzyme, which is responsible for converting androgens into estrogens. By blocking this conversion, letrozole effectively lowers estrogen levels, making it more difficult for certain types of breast cancer cells to grow and thrive.

Indications for Use

Letrozole is typically prescribed for:

Postmenopausal women with hormone receptor-positive breast cancer
Adjuvant treatment after surgery
Advanced breast cancer that has spread to other parts of the body

Dosage and Administration

The usual recommended dosage of letrozole is 2.5 mg taken once daily, with or without food. Treatment duration may vary based on individual patient response and the specific characteristics of the cancer being treated.
