Letroz 2.5mg is a prescription medication containing the active ingredient letrozole, which belongs to a class of drugs known as aromatase inhibitors. It works by blocking the aromatase enzyme, which significantly reduces the amount of estrogen produced in the body. This mechanism makes it a key treatment for hormone-receptor-positive breast cancer and an effective option for fertility therapy.
Primary Medical Uses
-
Breast Cancer Treatment: It is primarily prescribed to postmenopausal women to treat hormone-sensitive early or advanced breast cancer. Lowering estrogen levels helps slow down or stop the growth of cancer cells that rely on this hormone to multiply. It is often used as supportive (adjuvant) therapy after surgery, radiation, or standard tamoxifen treatment.
-
Fertility and Ovulation Induction: Though an off-label use in many regions, it is widely utilized in fertility clinics to treat infertility caused by anovulation (when the body does not regularly release an egg). By temporarily dropping estrogen levels, it prompts the pituitary gland to release follicle-stimulating hormone (FSH), which stimulates the ovaries to grow and release eggs.
