Letrozole is a non steroidal selective third-generation aromatase inhibitor. The structure and activity of the compound are very similar to the structure and activity of Ahna's trazole, and the clinical use is also consistent. The US prescription guidelines for letrozole suggest that it be used to treat breast cancer with estrogen receptor positive or estrogen receptor unknown postmenopausal women (not sure if cancer is reacting to estrogen). After estrogen receptor antagonists such as tamoxifen fail to cause the required response, they are usually used as the second therapeutic agent, and sometimes as the first therapeutic agent according to the situation. Male bodybuilders and athletes have found the ability of letrozole to reduce anabolic / androgen steroid related estrogen side effects, such as male breast development, fat accumulation and increased moisture.
