Exemestane is an aromatase inhibitor used to treat certain types of breast cancer in postmenopausal women.
Exemestane is a type of aromatase inhibitor, a medication that belongs to the steroid class of drugs. Its main purpose is to lower the amount of estrogen the body makes after menopause. In Hong Kong, the most common product that contains this ingredient is the brand-name tablet Aromasin.
Both the branded and generic versions come as solid tablets to be taken by mouth. The tablets may be supplied in blister packs or bottles, and the strength is clearly printed on the label.
These uses are approved by the Hong Kong Department of Health and are based on the drug’s ability to keep estrogen levels low, which helps limit the growth of certain breast tumours. The medication is generally prescribed for adult patients who are post-menopausal; it is not indicated for use in pre-menopausal individuals.
Exemestane blocks the enzyme called aromatase, which the body normally uses to turn other hormones into estrogen. By stopping this conversion, the drug reduces overall estrogen levels in the bloodstream. Lower estrogen means less fuel for cancers that rely on the hormone, slowing their development. The effect begins within a few days of starting treatment and continues as long as the medication is taken.
These reactions are generally mild and tend to improve with continued use. They are not unique to any one brand; they are typical for medicines that contain exemestane.
If any of these symptoms occur, prompt medical attention is required.
People who have known allergies to exemestane or to any of the tablet’s inactive ingredients should avoid the medication.
For a complete list of possible interactions, refer to the specific product’s information sheet.
Store tablets in a cool, dry place away from direct sunlight. Keep them out of reach of children. The typical treatment course can range from several months to a few years, depending on the health professional’s plan. Because strengths and formulation details differ between Aromasin and generic versions, always follow the directions printed on the product’s packaging. For detailed usage, dosing, and administration, refer to your specific medication’s information.
