Femistra 1mg Tablet is a prescription medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to the class of aromatase inhibitors, which work by reducing estrogen production in the body. Since certain types of breast cancers rely on estrogen to grow, lowering estrogen levels can slow or stop the growth of these tumors.

• Mechanism of action: Anastrozole inhibits the aromatase enzyme, which converts androgens into estrogen. This reduces circulating estrogen, effectively controlling the growth of hormone-sensitive breast cancer cells.

• Uses: It is prescribed for postmenopausal women with early-stage, advanced, or metastatic breast cancer, either as adjuvant therapy after surgery or as a standalone treatment for advanced disease.

• Forms: Available in tablet and capsule forms, providing flexibility and convenience for patient preferences.
