Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Irreversible steroidal aromatase inhibitor that binds to the aromatase enzyme, leading to its permanent inactivation via covalent modification. This reduces estrogen biosynthesis (primarily in peripheral tissues) by inhibiting conversion of androgens to estrogens.
Irreversible steroidal aromatase inhibitor; binds to the substrate-binding site of aromatase, causing permanent inactivation of the enzyme. Reduces estrogen synthesis by inhibiting conversion of androgens to estrogens.

Primarily hepatic metabolism via CYP3A4 and aldoketoreductases, with 60-70% of metabolites excreted renally and 30-40% via feces. Less than 1% excreted unchanged in urine.
