Arimidex (Anastrazole) was the first aromatase inhibitor available. It is therefore the most well known among anti-aromatases and the one doctors are most experienced with. Anti-Aromatases (Aromasin, Femara, Arimidex) are often confused with anti estrogens (Nolvadex). Anti-Aromatases work quite differently than Anti-Estrogens do. Anti-Estrogens are actually weak estrogens that attach to the estrogen receptor sites in the body (nipple & breast area), by doing so they block the 'bad' estrogens from attaching to these sites. Anti-Aromatases on the other hand block the formation of Estrogen in the body in the first place
