Mechanism of Action

Anastrozole reduces estrogen levels by blocking aromatase, the enzyme that converts androgens into estrogens in peripheral tissues. Lowering estrogen is essential in treating breast cancers that depend on this hormone for growth.

Indications

Arimidex is prescribed for postmenopausal women with hormone-receptor–positive breast cancer, whether the disease is localized or has spread. It’s also used after surgery to help lower the chance of the cancer returning.

Contraindications

This medication shouldn’t be used by anyone allergic to Anastrozole or any component of the tablet. It is not suitable for premenopausal women, as it does not work effectively in that group.

Precautions

Patients with a history of heart disease or low bone density should be monitored closely, as reduced estrogen may worsen these conditions. Long-term therapy often requires periodic bone density checks.

Drug Interactions

Anastrozole can affect, or be affected by, other medicines processed through the liver’s cytochrome P450 system. Patients should provide a full list of medications and supplements to their healthcare provider to help avoid interactions.

Dosage

The usual dose is 1 mg taken once daily. The length of treatment varies based on the patient’s condition and response, and any changes should only be made by a healthcare professional.

Storage

Keep the tablets in a cool, dry place away from direct light. Store at room temperature and out of reach of children.
