Treatment Summary
Anastrozole is a medication used to reduce estrogen levels in postmenopausal women with estrogen-sensitive breast cancer. It is a non-steroidal aromatase inhibitor, meaning it does not have the same side effects, such as weight gain and acne, that steroidal medications do. Anastrozole has become a preferred endocrine drug due to its effectiveness and fewer side effects than other medications, such as tamoxifen. Anastrozole was first approved for use in the United States in 1995.

How Anastrozole Affects Patients
Anastrozole helps treat breast cancer by stopping the body from converting androgens (like testosterone) into estrogen. It is taken once per day and can reduce levels of circulating estrogens by 70% after 24 hours. However, it has been linked to an increase in ischemic cardiovascular events, so patients with pre-existing heart disease should carefully consider the risks and benefits. Additionally, long-term use may reduce bone mineral density in the spine and hips, so monitoring of BMD is recommended.
How Anastrozole works in the body
Anastrazole works by blocking the enzyme that helps convert hormones into estrogen. This is especially important for postmenopausal women, since their estrogen levels are primarily derived from this conversion process. By blocking the enzyme, Anastrazole effectively lowers the body's estrogen levels and suppresses the growth of hormone-sensitive tumors.

Anastrozole Toxicity & Overdose Risk
The highest dose of anastrozole a woman has been reported to take was 1.68mg/kg given over 12 weeks. No one has taken more than 60mg of anastrozole, and the person who did experienced no serious effects. If someone overdoses on anastrozole, they should be monitored and given supportive treatment. Dialysis may be beneficial in some cases since anastrozole does not bind to proteins.
