Mechanism Of Action and Pharmacodynamic Effects Click here for help
Estrogen is primarily synthesized by conversion of adrenally-generated androstenedione to estrone by aromatase in peripheral tissues. Aromatase inhibition therefore, leads to a decrease in estrogen levels in both serum and cancer tissue. In estrogen-responsive tumors this results in decreased tumor mass and in some women, delayed tumor growth.
