Aromatase inhibitors are a class of medications that help reduce estrogen levels in the body. They are primarily used in the treatment of hormone-sensitive breast cancer in postmenopausal women and are also popular in sports for their potential benefits in improving male hormone levels. Understanding the correct dosage of aromatase inhibitors is crucial for maximizing their effectiveness while minimizing side effects.
