Exemestane – What You Need to Know

When working with Exemestane, a steroidal aromatase inhibitor primarily used in hormone‑responsive breast cancer. Also known as Aromasin, it blocks estrogen production and helps slow tumor growth. As an Aromatase Inhibitor, Exemestane targets the enzyme that converts androgens to estrogen, reducing the hormone that can fuel certain tumors. In the context of Breast Cancer, especially estrogen‑receptor‑positive (ER+) disease, this reduction translates into lower recurrence rates after surgery or chemotherapy. The drug also fits within broader Hormone Therapy strategies, where doctors balance estrogen suppression with side‑effect management to improve long‑term outcomes. The drug Exemestane is often prescribed after a course of tamoxifen or as a first‑line option for post‑menopausal patients.

How Exemestane Works and What to Expect

Exemestane’s mechanism is irreversible: it binds permanently to the aromatase enzyme, causing a sustained drop in circulating estrogen. Typical dosing is 25 mg once daily, taken with or without food, and treatment periods can range from six months to several years depending on disease stage. Because estrogen also supports bone density, patients on Exemestane often see a modest decrease in bone mineral content; regular DEXA scans and calcium/vitamin D supplementation are standard precautions. Common side effects include hot flashes, joint pain, fatigue, and mild nausea—symptoms that mirror natural menopause and can be managed with lifestyle tweaks or short‑term medications. Rare but serious risks involve elevated cholesterol levels and liver enzyme changes, so baseline labs and periodic monitoring are essential.

Drug interactions are another key piece of the puzzle. Antifungals like ketoconazole, certain anticonvulsants, and strong CYP3A4 inducers can alter Exemestane levels, potentially reducing its efficacy or increasing toxicity. Patients should also inform their doctors about over‑the‑counter supplements, especially phytoestrogen‑rich products that might counteract estrogen suppression. When planning surgery or radiation, clinicians often pause Exemestane for a few weeks to allow estrogen levels to rebound and aid wound healing. Overall, the choice of Exemestane hinges on a patient’s menopausal status, bone health, cardiovascular profile, and personal tolerance for side effects.
