Anastrozole: What Is It?
Anastrozole is a medication commonly prescribed in the treatment of breast cancer, particularly in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which function by reducing estrogen levels in the body. This reduction is critical because certain types of breast cancer rely on estrogen to grow and spread.
How Does Anastrozole Work?
The mechanism of action of anastrozole involves the inhibition of the aromatase enzyme, which is responsible for converting androgens into estrogens in peripheral tissues. By blocking this conversion, anastrozole effectively lowers the amount of circulating estrogen, thereby slowing or stopping the growth of estrogen-dependent tumors.
Indications for Use
Anastrozole is mainly indicated for:
- Treatment of hormone receptor-positive breast cancer in postmenopausal women.
- Adjuvant therapy following surgery to reduce the risk of cancer recurrence.
- Treatment of advanced breast cancer in patients who have progressed on tamoxifen therapy.
Dosing and Administration
The typical dose of anastrozole is 1 mg taken orally once daily. It can be administered with or without food, making it convenient for daily use. Treatment duration varies based on individual patient factors, including Arimidex 1 mg Beragena the stage of cancer and response to therapy.

It is important for patients to discuss potential side effects with their healthcare provider and undergo regular monitoring during treatment.
Conclusion
In summary, anastrozole is a pivotal drug in the management of certain types of breast cancer. Its ability to effectively lower estrogen levels makes it a valuable option for many women facing this disease. Understanding how anastrozole works and its implications for treatment can empower patients to make informed decisions alongside their healthcare team.
