Documented Uses

Used as rodenticide and therapeutic anticoagulant; Discontinued as a medication; [HSDB]
The Approved Drug Products with Therapeutic Equivalence Evaluations List identifies discontinued drug products. Dicumarol is included on this list.
Dicoumarol is a mycotoxin of combined plant and fungal origin. It is a derivative of coumarin, a substance made by plants which is transformed in mouldy feeds by a number of species of fungi into active dicoumarol. Dicoumarol is an anticoagulant that is used along with heparin for the treatment of deep venous thrombosis, as well as in biochemical experiments as an inhibitor of reductases. (L1960)
Originally isolated from spoiled sweet clover (improperly cured Melilotus hay) ... now prepared synthetically by the action of formaldehyde on 4-hydroxy-coumarin (obtained as the Na derivative by the action of sodium metal on methyl acetylsalicylate) ... .
2H-1-Benzopyran-2-one, 3,3'-methylenebis[4-hydroxy-: ACTIVE
ADVANTAGE AS RAT POISON IS THAT TREATED ANIMALS DO NOT DEVELOP "BAIT SHYNESS". AS RODENTICIDE, DICOUMAROL IS NOWADAYS SUPERSEDED BY WARFARIN.
