Introduction to anastrozole what is
Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. When people inquire anastrozole what is, they are seeking to understand its purpose, mechanism, and proper use.
What is anastrozole?
Anastrozole is classified as an aromatase inhibitor. Aromatase is an enzyme responsible for converting androgens into estrogens in the body. By inhibiting this enzyme, anastrozole reduces estrogen levels, which can help slow or stop the growth of estrogen-dependent breast cancer cells.
Key Facts about Anastrozole what is
- Generic name: Anastrozole
- Brand name: Arimidex
- Medication type: Non-steroidal aromatase inhibitor
- Commonly prescribed for: Hormone receptor-positive breast cancer in postmenopausal women
- Administration: Oral tablets
How Does Anastrozole Work?
By blocking the aromatase enzyme, anastrozole decreases estrogen production. Since many breast cancers grow in response to estrogen, lowering estrogen levels can effectively inhibit tumor growth and reduce the risk of recurrence.
Mechanism of Action
- The body normally converts androgens into estrogens via aromatase.
- Anastrozole binds to the aromatase enzyme, preventing it from functioning.
- This results in decreased estrogen synthesis.
- Lower estrogen levels lead to reduced stimulation of hormone-sensitive breast cancer cells.
Uses of Anastrozole
Besides its primary indication, anastrozole may also be used off-label for other conditions under medical supervision. Its main uses include:
- Adjuvant therapy in early-stage breast cancer
- Treatment of metastatic breast cancer
- Management of hormone-responsive tumors

Common Side Effects
- Hot flashes
- Joint pain or stiffness
- Weakness or fatigue
- Nausea
- Hair thinning
Serious Side Effects
- Osteoporosis or bone fractures
- Signs of blood clots

Frequently Asked Questions (FAQs)
Q1: anastrozole what is best used for?
Anastrozole is mainly used to treat hormone-receptor-positive breast cancer in postmenopausal women.
Q2: How does anastrozole differ from other breast cancer treatments?
It specifically inhibits aromatase, reducing estrogen production, unlike selective estrogen receptor modulators (SERMs) like tamoxifen that block estrogen receptors.
Q3: Are there any lifestyle considerations while taking anastrozole?
Patients are advised to maintain adequate calcium and vitamin D intake and engage in weight-bearing exercises to support bone health, as anastrozole may decrease bone density.
Q4: Can men take anastrozole?
Although primarily prescribed for women, anastrozole may sometimes be used in men for certain conditions such as gynecomastia, but only under strict medical supervision.
Conclusion
Anastrozole plays a vital role in hormone-driven breast cancer therapy. Understanding anastrozole what is helps patients and caregivers make informed decisions about treatment options.
