Anzatax Injection is used for the treatment of specific types of breast cancer, ovarian cancer and non small cell lung cancer (NSCLC). Anzatax is part of a group of anti-cancer drugs that works by killing the tumour cells as they grow and multiply. This is called an anti-neoplastic agent (neoplasm is another term to describe a cancer or tumour). Your oncologist (cancer doctor) will decide what dose of Anzatax is best for you. The amount given depends on your type of cancer, your weight, your kidney function and other medical problems that you may suffer from.
