Letrozole 2.5 mg Tablet
Letrozole is a nonsteroidal aromatase inhibitor. It exerts its antitumor effect by depriving estrogen-dependent breast cancer cell of their growth stimulus. Letrozole inhibits the aromatase enzyme by competitively binding to the heme of the cytochrome P450 subunit of the enzyme, resulting in a reduction of estrogen biosynthesis in all tissues.
