Exemestane 20mg

Exemestane (brand name Aromasin) is a prescription aromatase inhibitor used primarily as hormone therapy for estrogen receptor-positive breast cancer in postmenopausal women. It works by irreversibly blocking the aromatase enzyme, which is responsible for converting androgens into estrogen; lowering estrogen levels helps slow or stop the growth of tumors that depend on estrogen. Exemestane is most commonly prescribed as a 25 mg oral tablet taken once daily after a meal, but the term “20 mg” is often used informally to refer to this standard daily dose in clinical practice. It is indicated for use in postmenopausal women with early-stage estrogen receptor-positive breast cancer, particularly following treatment with tamoxifen, and for advanced breast cancer that has progressed after anti-estrogen therapy.
