Letrozole is a medication that belongs to a class of drugs known as aromatase inhibitors. It is commonly used in the treatment of breast cancer, particularly in postmenopausal women.

Aromatase inhibitors work by blocking the enzyme aromatase, which is responsible for converting androgens into estrogen. By inhibiting this process, letrozole helps lower the levels of estrogen in the body, which can slow the growth of estrogen-sensitive tumors.

Aside from its use in breast cancer treatment, letrozole is also sometimes prescribed off-label for other conditions such as infertility in women with polycystic ovary syndrome (PCOS). In this case, letrozole can help stimulate ovulation by balancing hormone levels.

Letrozole is typically taken orally in the form of tablets, and the dosage will vary depending on the individual’s condition and response to the medication. Like all medications, letrozole may cause side effects, so it is important to discuss any concerns with a healthcare provider before starting treatment.
