Aritoz contains anastrozole, which is a medication primarily used to treat breast cancer in postmenopausal women. It belongs to a class of drugs called aromatase inhibitors. Anastrozole works by lowering the amount of estrogen the body produces, as estrogen can encourage the growth of certain types of breast cancer.

Mechanism of Action
Anastrozole works by blocking the aromatase enzyme, which is responsible for converting androgens into estrogen in the body. By reducing estrogen levels, anastrozole helps slow down or stop the growth of estrogen-dependent breast cancer cells. This targeted approach is particularly effective in hormone receptor-positive breast cancers.

Uses
Aritoz is mainly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It is often prescribed as part of adjuvant therapy after surgery or radiation to reduce the risk of cancer returning. It may also be used in advanced or metastatic cases to help control disease progression.

Adverse Effects
Common side effects of anastrozole may include hot flashes, joint pain or stiffness, weakness, headache, and mood changes. Some women may experience thinning of bones or an increased risk of osteoporosis with long-term use. Less commonly, it may cause elevated cholesterol levels or skin rashes. Regular monitoring by a healthcare provider helps manage these risks.
