Exemestane is an endocrine therapy used primarily in the treatment of breast cancer by lowering oestrogen levels in the body. It works by irreversibly binding to the aromatase enzyme, preventing hormone-driven tumour growth. Our platform offers UK patients reliable access to generic medications containing Exemestane. We focus on providing high-quality, authentic pharmaceutical options for those requiring consistent long-term treatment as part of their oncology care plan.
Exemestane is a synthetic steroid that belongs to the class of aromatase-inhibiting medicines. It works by reducing the amount of estrogen the body makes. In the UK, the most widely known product that contains this ingredient is the tablet brand Aromasin.
In the United Kingdom, the primary medication you will see marketed with exemestane is Aromasin. It is usually supplied as oral tablets, commonly in a 25 mg strength. Generic versions of exemestane are also available and are often prescribed under the same dosage form. Although the brand name may differ between pharmacies, the active ingredient remains the same.
Exemestane is used in the management of hormone-sensitive conditions, most notably:
These uses reflect the way the medicine lowers circulating estrogen, which can slow the growth of cells that rely on that hormone.
Exemestane blocks the enzyme aromatase, which is responsible for converting androgens into estrogen. By limiting this conversion, the overall estrogen level in the bloodstream drops. Lower estrogen reduces the stimulus for hormone-sensitive tumour cells, helping to control their growth. The effect usually begins within a few days of starting treatment, though the full impact may become evident over several weeks.
People taking medicines that contain exemestane often notice mild, temporary effects such as:
These symptoms are usually not severe and often improve with continued use.
