Mechanism & Pharmacology

Simplified explanation

Arimidex, generically known as anastrozole, is primarily used for treating breast cancer in postmenopausal women. It works by inhibiting an enzyme called aromatase, which is responsible for converting androgens into estrogens. By reducing estrogen levels, Arimidex slows down the growth of hormone-sensitive tumors. Patients should be aware of potential side effects such as hot flashes, fatigue, and joint pain.

Clinical terms

According to Health Canada, Arimidex belongs to the pharmacological class of aromatase inhibitors (ATC code: L02BG03). This classification categorizes it as an endocrine therapy agent used in the management of breast cancer. The mechanism of action involves blocking estrogen production in the body, thereby offering therapeutic benefits to patients with specific types of breast cancer.

Indications & Off-Label Uses in Canada

Approved indications

The Drug Identification Number (DIN) for Arimidex confirms its approval for use in Canada. It's prescribed primarily for early and advanced hormone receptor-positive breast cancer in postmenopausal women. The standard dosage is 1 mg once daily, either as part of an adjuvant treatment following surgery or as a first-line treatment for metastatic cases.

Common off-label practices

Canadian physicians may also prescribe Arimidex off-label for other indications, although these should always be approached under medical guidance. Examples include off-label use in treating conditions related to hormonal imbalances or in certain male patients for symptoms of gyno. It is crucial to always follow a healthcare provider's advice when considering off-label use.

Key Clinical Findings
