Femara(Femara) Instructions:Uses,Dosage, Side Effects

Femara, with the generic name Letrozole, is an oral, non-steroidal aromatase inhibitor. Its primary mechanism of action involves the potent and selective inhibition of the aromatase enzyme, which is responsible for the synthesis of estrogen. By significantly reducing circulating estrogen levels in postmenopausal women, it targets hormone-sensitive pathways that are crucial for the growth and proliferation of certain types of breast cancer cells, forming the basis of its therapeutic application.
