Irinotecan (Camptosar)
General information
Class/mechanism: Topoisomerase I inhibitor; derivative of camptothecin, which interferes with topoisomerase I's normal action of relieving torsional strain in DNA by creating reversible
single-strand breaks. Irinotecan and its active metabolite SN-38 bind to the topoisomerase
I & DNA complex and interfere with ligation of these single-strand breaks. Failure to repair these breaks eventually leads to double-strand DNA damage, which disrupts cell proliferation and leads to cell death.[1][2]
Route: IV
Extravasation: irritant
