A theoretical advantage of steroidal over non steroidal aromatase inhibitors is that covalent binding of the drug to the active site of the enzyme irreversibly inhib - its aromatase action.12,13 However, exemestane has not Alibaba.com offers 776 letrozole anastrozole products.

ALIQUOT (Anastrozole vs. Letrozole, an Investigation of Quality Of Life and Tolerability) was a prospective, open-label, randomized pharmacodynamic study designed to assess the effects of aromatase inhibitors (AIs) on bone turnover in healthy postmenopausal women with estrogen receptor-positive breast cancer. How letrozole solves gynecomastia? Letrozole (femara) is the strongest oral aromatase inhibitor (AI) available, and studies have shown that it will drop estrogen levels in men by 65% and 98% in women. Hence, this makes letro more powerful than the popular AI's aromasin and arimidex (anastrozole). Anastrozole and letrozole are nonsteroidal, reversible inhibitors of the aromatase enzyme and prevent the conversion of androgens to estrogens (Fig. 36-3).
