Aromatase inhibitors are a class of drugs used primarily to treat hormone receptor-positive breast cancer in postmenopausal women. They work by inhibiting the enzyme aromatase, which converts androgens to estrogens. This reduction in estrogen levels is beneficial for patients who are hormone-sensitive. Understanding the appropriate dosage of aromatase inhibitors is crucial for maximizing their effectiveness while minimizing potential side effects.
