Aromasin (Exemestane)

Aromasin (exemestane) is an oral aromatase inhibitor used to treat estrogen-receptor positive breast cancer in postmenopausal women.

It is prescribed for:

• Adjuvant treatment of early breast cancer in postmenopausal women who have received 2–3 years of tamoxifen, to complete a total of 5 years of hormonal therapy.

• Advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.

How it works:

Aromasin lowers estrogen levels by blocking aromatase, an enzyme responsible for converting androgens to estrogens. This reduction limits the growth of hormone-sensitive breast tumors.

Dosage:

Typically, one 25 mg tablet taken once daily after a meal.

Warnings:

Not for use in premenopausal women or during pregnancy. Common side effects include hot flashes, fatigue, joint pain, and bone thinning.

Aromasin is available by prescription only and should be used under medical supervision.
