Exemestane is a medicine used to manage certain types of breast cancer. Stopping natural hormone production helps decrease the energy source needed for these abnormal cells.
When estrogen levels need to be lowered in certain cancers, a drug called exemestane may be used. It belongs to the class of steroidal aromatase inhibitors, which means it blocks the enzyme that makes estrogen from other hormones. By reducing estrogen, exemestane helps manage hormone-sensitive breast cancer, especially after menopause. This active compound is found in products marketed as Aromasin.
Patients may encounter exemestane under the brand name Aromasin, which is widely available in Singapore pharmacies and hospitals. The medication is typically supplied as oral tablets, although generic versions may appear on the market with the same active ingredient. In Singapore, both the brand and generic forms must meet health-authority standards, and they are dispensed by qualified healthcare providers.
Hormone-sensitive breast cancer is the primary condition where exemestane is considered. It is commonly used after surgery to help lower the risk of cancer returning in post-menopausal women. Advanced or metastatic breast cancer, where the disease has spread, may also be managed with exemestane as part of a broader treatment plan. Some clinicians employ the drug to support hormone therapy in early-stage disease, aiming to keep cancer cells from growing. Generally, the medication is intended for adults who have reached menopause and whose tumors rely on estrogen.
By blocking the enzyme aromatase, exemestane reduces the body’s production of estrogen, a hormone that can fuel certain breast cancers. Lower estrogen levels mean fewer signals for cancer cells to grow, allowing other treatments to work more effectively. The drug’s action is irreversible, meaning it permanently deactivates the enzyme for the duration of its presence in the body.
Mild hot flashes, joint or muscle aches, occasional fatigue, and brief nausea are frequently reported. Some people notice a small, temporary loss of bone density, which doctors often monitor during treatment.
Rare but important warnings include severe bone thinning that could lead to fractures, liver inflammation, blood clot formation, and allergic reactions such as rash, swelling, or difficulty breathing. Prompt medical attention is needed if any of these signs appear.
Exemestane should be avoided in individuals who are pregnant, have a known allergy to the drug, or suffer from serious liver impairment. Because the medication works by lowering estrogen, it is not suitable for pre-menopausal women.
The drug may interact with other hormonal therapies, certain antifungal medications, and some blood-thinning agents. Alcohol consumption can also increase the risk of liver-related issues. Always refer to the specific medication’s labeling or package information for exact interaction details.
Storing these tablets in a cool, dry place helps maintain their quality. Treatment length can range from several months to several years, depending on the individual’s condition and the specific Aromasin product used. Different brands may vary in strength and excipient composition, so follow the information that comes with each package. For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
