Mechanism of action

FEC combines fluorouracil (a thymidylate synthase inhibitor), epirubicin (a topoisomerase II inhibitor and intercalating agent), and cyclophosphamide (an alkylating agent). Together, these agents work synergistically to disrupt DNA synthesis and repair, leading to cancer cell death. The combination is designed to provide broad cytotoxic activity against rapidly dividing cells.
