Mechanism of Action1,2
Letrozole binds to heme group of the cytochrome P450 subunit of the aromatase (enzyme) resulting in a reduction of estrogen (estrone, estradiol and estrone sulfate) biosynthesis in all tissues. The drug decreases estrogen levels by preventing the conversion of androgens to estrogen.
