Letrozole is a new generation of highly selective aromatase inhibitors, which is a synthetic benztriazole derivative. By inhibiting aromatase, estrogen levels can be reduced, thereby eliminating the stimulating effect of estrogen on tumor growth. In vivo activity is 150-250 times stronger than that of the first generation aromatase Chemicalbook inhibitor ammoniumide. Because of its high selectivity, it does not affect glucocorticoids, corticosteroids and thyroid function, and large doses have no inhibitory effect on the secretion of adrenal corticosteroids, so it has a high therapeutic index.
