ANASTRONAT 1mg Tablet contains the active substance Anastrozole. It belongs to a group of medicines known as Aromatase Inhibitors. It is primarily indicated for the treatment of hormone receptor-positive breast cancer in postmenopausal women. It is used in early-stage breast cancer, advanced breast cancer, and in patients whose disease has progressed following tamoxifen therapy.
Anastrozole works by reducing the production of estrogen in the body. Since many breast cancer cells depend on estrogen for growth, lowering estrogen levels helps slow or stop the growth of hormone-sensitive cancer cells.
