What is Exemestane?
Exemestane (Aromasin — irreversible steroidal aromatase inhibitor (Type I AI)) is a Small molecule C₂₀H₂₄O₂, MW 296.4. Irreversible steroidal aromatase inhibitor (Type I, mechanism-based) that covalently inactivates CYP19A1 after single binding — unlike reversible non-steroidal AIs. Complete suppression of oestrogen synthesis in all tissues. FDA approved for breast cancer. No rebound aromatisation after discontinuation.
