Exemestane – What It Is, How It Works, and What to Expect

When dealing with Exemestane, a steroidal aromatase inhibitor used to treat hormone‑responsive breast cancer. Also known as Aromasin, it blocks the enzyme that converts androgens to estrogen, effectively lowering estrogen levels in the body. This action makes it a core component of hormone therapy, treatment that targets hormonal pathways to slow or stop cancer growth. Because estrogen fuels many breast tumors, cutting its production can shrink tumors and reduce recurrence risk. exemestane is especially popular after menopause or in patients who can’t tolerate other aromatase inhibitors.

Key Considerations for Using Exemestane

Understanding the relationship between aromatase inhibitor, a class of drugs that suppress estrogen synthesis and breast cancer, a disease where cells grow uncontrollably in breast tissue is crucial. Exemestane is prescribed when the cancer is estrogen‑receptor‑positive, meaning the tumor cells rely on estrogen to thrive. The drug’s steroidal structure means it binds permanently to the aromatase enzyme, offering a “one‑and‑done” inhibition that can be more effective for some patients. Typical dosing is 25 mg once daily, taken with water, and it’s often continued for five years or as directed by an oncologist. Monitoring includes regular bone density tests, because reduced estrogen can affect bone health, and liver function checks since the liver metabolizes the medication.

Side effects vary, but the most common include joint and muscle aches, hot flashes, and mild fatigue. Some users report mood changes or sleep disturbances, which can be managed with lifestyle tweaks or supportive therapies. Rarely, severe liver issues or high cholesterol may arise, so staying in touch with your healthcare team is essential. When side effects become troublesome, doctors may switch to another aromatase inhibitor like letrozole or anastrozole, or adjust the dose. Beyond cancer care, a few patients explore exemestane for off‑label uses such as managing estrogen‑related conditions, though evidence is limited. Overall, the drug’s ability to lower estrogen makes it a powerful tool in the fight against hormone‑driven breast cancer, and understanding its role, benefits, and risks helps you make informed decisions.
