Anastrozole belongs to the class of medications known as aromatase inhibitors. It is primarily used to treat breast cancer in postmenopausal women by reducing the amount of oestrogen the body produces. This potent active ingredient is available in many verified generic forms that provide cost-effective treatment options. Our pharmacy offers secure access to licensed medications containing Anastrozole to support ongoing health management.
Anastrozole belongs to a class of medicines known as aromatase inhibitors. Its main role is to lower the amount of estrogen made by the body. This reduction helps treat conditions that are driven by estrogen, most commonly certain types of breast cancer. You’ll find anastrozole as the active ingredient in several products available in the UK, such as Arimidex, Armotraz and the generic version simply called Anastrozole.
In the United Kingdom, anastrozole is marketed under a few different names. Arimidex is the well-known brand, supplied as 1 mg tablets. Armotraz is another brand that offers the same 1 mg tablet strength. The generic version, labelled Anastrozole, is also sold in 1 mg tablets by a range of manufacturers. All of these formulations are oral tablets, designed for daily use, and are generally prescribed in the same dosage strength, although the exact packaging and brand name may differ between pharmacies.
These are the primary approved uses in the UK. Some clinicians may consider anastrozole for other estrogen-related conditions, but such uses fall outside the formal licensing and should be discussed with a specialist.
Anastrozole blocks the enzyme aromatase, which converts androgens into estrogen in peripheral tissues. By inhibiting this step, the drug reduces overall estrogen levels in the bloodstream. Lower estrogen means less hormonal stimulation for cancers that rely on the hormone to grow, helping to keep tumour growth under control. The effect on estrogen levels is typically noticeable within a few days of starting treatment, although the clinical benefit may take weeks to become evident.
These reactions are generally short-lived and resolve on their own, but they can vary from person to person.
If any of these occur, seek urgent medical attention.

Keep tablets in their original container, stored at room temperature away from moisture and direct sunlight. Anastrozole-containing medicines are usually prescribed for a defined period, often several years for chronic hormone-responsive conditions, but the exact length depends on the individual product and the patient’s treatment plan. Always follow the instructions that come with your specific medication; variations can exist between brands.
Aromatase inhibitor: A drug that stops the enzyme aromatase from making estrogen.
Adjuvant therapy: Additional treatment given after the primary therapy to reduce the risk of cancer returning.
Metastatic disease: Cancer that has spread from its original location to other parts of the body.
