Generic Anastrozole Information

Introduction

Anastrozole is an oral medication primarily used to treat hormone‑responsive breast cancer in post‑menopausal women. The active compound, Anastrozole, belongs to the class of aromatase inhibitors and is positioned within the Women’s Health therapeutic group. In Hong Kong, it is prescribed by oncologists and endocrine specialists as part of adjuvant, neoadjuvant, or metastatic breast‑cancer regimens. Although its main indication is breast‑cancer management, clinical guidelines also recognize off‑label uses such as estrogen‑related gynecological conditions and certain cases of male infertility associated with excess estrogen.

What is Anastrozole?

Anastrozole is a selective, non‑steroidal aromatase inhibitor. It was originally developed by the pharmaceutical company AstraZeneca and marketed worldwide under the brand name Arimidex. The medication is now available as a generic product that contains the identical active compound, Anastrozole, in tablet form.

Anastrozole is the generic version of Arimidex, containing the same active compound Anastrozole. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

The generic formulation is manufactured by several reputable producers who meet international Good Manufacturing Practice (GMP) standards. In Hong Kong, the drug is regulated by the Department of Health’s Pharmacy and Poisons Board and can be dispensed only with a valid prescription.

How Anastrozole Works

Aromatase is an enzyme that converts androstenedione and testosterone into estrone and estradiol, respectively. In post‑menopausal women, the majority of circulating estrogen is produced via this peripheral conversion. Anastrozole binds reversibly to the aromatase enzyme’s heme group, inhibiting its activity by up to 97 % at therapeutic doses.

By suppressing estrogen synthesis, Anastrozole reduces the stimulation of estrogen‑dependent tumor cells, slowing growth and inducing apoptosis. The onset of estrogen suppression typically occurs within 24 hours of the first dose, and steady‑state plasma concentrations are reached after approximately 7 days of once‑daily dosing. The drug’s half‑life is roughly 50 hours, allowing for consistent hormonal control with a single daily tablet.

Conditions Treated with Anastrozole

• Hormone‑receptor‑positive breast cancer (post‑menopausal) – primary approved indication for adjuvant, neoadjuvant, and metastatic settings.
• Prevention of breast‑cancer recurrence – used after surgery and radiation to lower the risk of new tumors.
• Estrogen‑related gynecological disorders – off‑label use in conditions such as endometriosis and uterine fibroids where estrogen drives tissue proliferation.
• Male gynecomastia or infertility due to estrogen excess – occasional off‑label application to restore hormonal balance.

In Hong Kong, breast cancer accounts for approximately 12 % of all female cancers, with an estimated 7,600 new cases diagnosed annually (Hong Kong Cancer Registry, 2023). Approximately 70 % of these tumors express estrogen receptors, making aromatase inhibition a cornerstone of standard care.

Patient Groups Most Likely to Benefit

• Post‑menopausal women with estrogen‑receptor‑positive (ER⁺) breast cancer – strongest evidence of benefit, both in early‑stage and advanced disease.
• Women who cannot tolerate selective estrogen‑receptor modulators (SERMs) such as tamoxifen – Anastrozole offers a different safety profile, avoiding thromboembolic risk.
• Patients undergoing hormone‑sensitive gynecologic surgery – may benefit from temporary estrogen suppression to reduce recurrence.
• Men with hormonally driven conditions – only under specialist supervision, typically when elevated estradiol contributes to symptoms.

Anastrozole is not appropriate for pre‑menopausal women, pregnant or lactating individuals, and patients with severe hepatic impairment without dose adjustment.

Risks, Side Effects, and Interactions

Common

• Hot flashes
• Joint and muscle pain (arthralgia, myalgia)
• Fatigue
• Nausea or mild gastrointestinal upset
• Decreased bone mineral density (osteopenia)

Rare

• Elevated liver enzymes (ALT, AST)
• Mood changes, including depression or anxiety
• Skin rash or pruritus
• Dyslipidaemia (increase in LDL cholesterol)

Serious

• Severe osteoporosis leading to fracture
• Venous thromboembolism (rare but reported)
• Acute liver injury (hepatitis)
• Allergic anaphylaxis (extremely rare)

Drug–Drug Interactions

• Tamoxifen – concurrent use may antagonize each other; clinicians usually avoid combination.
• Antifungal agents (e.g., ketoconazole, itraconazole) – CYP3A4 inhibition can increase Anastrozole plasma levels.
• Anticonvulsants (e.g., carbamazepine, phenytoin) – CYP3A4 induction may reduce efficacy.
• Corticosteroids – may compound bone‑loss risk; bone‑protective strategies recommended.

Patients should disclose all prescribed, over‑the‑counter, and herbal products before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dose: 1 mg tablet taken orally once daily, with or without food.
• Renal impairment: No dose adjustment required; monitor for accumulation in severe cases.
• Hepatic impairment: Use with caution; consider dose reduction to .5 mg daily if Child‑Pugh class C.

Missed dose – If a dose is forgotten within 12 hours, take it as soon as remembered. Skip the missed dose if it is almost time for the next scheduled dose; do not double‑dose.

Overdose – Signs may include severe gastrointestinal upset, dizziness, or acute bone pain. Immediate medical evaluation is advised; treatment is supportive, focusing on symptom control and monitoring of hepatic function.

Precautions – Avoid excessive alcohol, which can exacerbate liver toxicity. Calcium and vitamin D supplementation, along with weight‑bearing exercise, are recommended to counteract bone loss. Routine bone‑density scans (DEXA) are advised every 1–2 years during long‑term therapy.

FAQ

• Is Anastrozole available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand, Arimidex, is marketed by AstraZeneca, while multiple generic manufacturers produce tablets containing the same active compound, Anastrozole. The generic version is typically less expensive and is widely prescribed.

• Can I store Anastrozole at home without refrigeration?
  Anastrozole tablets should be kept at room temperature, between 15 °C and 30 °C (59 °F–86 °F). Protect them from excess heat, moisture, and direct sunlight; no refrigeration is required.

• What packaging does Anastrozole come in when ordered online?
  Tablets are supplied in sealed, tamper‑evident blister packs or bottles, each containing a specific number of 1 mg tablets as indicated on the label. The outer shipping box is discreet and includes a printed invoice for customs clearance.

• Is it legal to import Anastrozole for personal use into Hong Kong?
  Importation of prescription medicines for personal use is permitted when a valid prescription is presented to customs. Our online pharmacy arranges the necessary documentation to comply with Hong Kong regulations, ensuring lawful import.

• Are there any known differences in formulation between regions (e.g., US vs EU vs Asia)?
  The active ingredient, Anastrozole, is identical across regions. Inactive excipients such as lactose, microcrystalline cellulose, and magnesium stearate may vary slightly between manufacturers, but these differences do not affect therapeutic efficacy.

• Do Asian populations experience any unique side‑effects with Anastrozole?
  Clinical studies have not identified ethnicity‑specific adverse events. However, some Asian patients may have a higher baseline risk of osteopenia, underscoring the importance of bone‑health monitoring during therapy.

• Can Anastrozole be used together with hormone‑replacement therapy (HRT)?
  No. Anastrozole suppresses estrogen production, directly opposing the purpose of HRT. Concurrent use may neutralise the effects of both agents and is not recommended.

• How often should bone density be checked while on Anastrozole?
  Baseline dual‑energy X‑ray absorptiometry (DEXA) is advised before initiating treatment, followed by repeat scans every 12–24 months for patients on long‑term therapy, especially those with additional risk factors for osteoporosis.

• Is there a risk of drug resistance developing with prolonged Anastrozole use?
  Some tumors may acquire resistance through up‑regulation of alternate estrogen‑synthesis pathways or mutations in the aromatase gene. Continuous monitoring of disease markers and periodic imaging are essential to detect progressive disease early.

• Can I obtain Anastrozole without a local physician’s prescription through the online service?
  Our online pharmacy partners with licensed physicians who review your medical information remotely and issue a prescription electronically. This process complies with Hong Kong law, allowing you to receive Anastrozole without a separate in‑person prescription.
