Arimidex (Anastrozole) In Australia
Arimidex (Anastrozole) in Australia, Arimidex (generic name Anastrozole) is a prescription medication used in Australia to treat hormone receptor–positive breast cancer, particularly in postmenopausal women.
It works by lowering estrogen levels, helping slow or stop the growth of certain types of breast cancer cells that depend on estrogen to multiply.
What Is Arimidex (Anastrozole)?
Arimidex belongs to a class of medicines known as aromatase inhibitors. These drugs block the enzyme aromatase, which converts androgens (male hormones) into estrogen in the body.
By reducing estrogen levels, Arimidex helps:
-
Prevent cancer recurrence after initial treatment
-
Shrink tumors that are hormone receptor–positive
-
Support ongoing therapy following surgery, chemotherapy, or radiation
Approved Medical Uses in Australia
In Australia, Arimidex 1mg tablets are approved by the Therapeutic Goods Administration (TGA) for:
-
Treatment of early or advanced breast cancer in postmenopausal women
-
Use as adjuvant therapy after tamoxifen treatment
-
Certain off-label hormonal disorders under specialist supervision
Arimidex is not legally available without a prescription, and self-medicating or using it for unapproved purposes (such as bodybuilding or hormone manipulation) is unsafe and illegal. Arimidex (Anastrozole) in Australia
