Letrozole is a prescription medication belonging to the aromatase inhibitor class. It works by reducing the production of estrogen in the body, helping limit estrogen stimulation of hormone-sensitive cells.

It is primarily used in the treatment of certain hormone receptor-positive breast cancers in postmenopausal women. Depending on local medical guidelines, letrozole may also have other specialist-approved applications.

Because treatment significantly alters estrogen levels, appropriate medical evaluation and monitoring are important throughout therapy.
