Anastrozole is a drug to treat breast cancer in postmenopausal women. Anastrozole can be given to patients whose condition does not improve after treatment with tamoxifen

Anastrozole works by lowering estrogen levels in the body by inhibiting the aromatase enzyme. That way, it is hoped that the size of the tumor will shrink and the growth of cancer cells can be inhibited.
Please note, anastrazole should not be used by men, children or women who have not been through menopause.
