Mechanism of action

Irinotecan inhibits topoisomerase I, an enzyme essential for unwinding and rewinding DNA during replication. By stabilizing the topoisomerase I-DNA complex, the drug prevents the religation of DNA strands, causing double-strand breaks and apoptosis in rapidly dividing cancer cells. It is a prodrug that is converted to its active metabolite SN-38 by carboxylesterase in the liver and tissues.
