Letrozole: Description of the Drug
Letrozole is a medication primarily used in the treatment of certain types of breast cancer, particularly hormone receptor-positive breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the amount of estrogen produced by the body.
Mechanism of Action
The primary function of letrozole is to inhibit the enzyme aromatase, which is responsible for converting androgens into estrogen. By blocking this conversion, letrozole effectively lowers estrogen levels in the body, which can help slow or stop the growth of hormone-sensitive tumors.
