Dicoumarol is a natural chemical substance of combined plant and fungal origin. It is a derivative of coumarin, a bitter-tasting but sweet-smelling substance made by plants that does not itself affect coagulation, but which is (classically) transformed in mouldy feeds or silages by a number of species of fungi, into active dicoumarol. Dicoumarol does affect coagulation, and was discovered in mouldy wet sweet-clover hay, as the cause of a naturally occurring bleeding disease in cattle.^[1] See warfarin for a more detailed discovery history.

Identified in 1940, dicoumarol became the prototype of the 4-hydroxycoumarin anticoagulant drug class. Dicoumarol itself, for a short time, was employed as a medicinal anticoagulant drug, but since the mid-1950s has been replaced by its simpler derivative warfarin, and other 4-hydroxycoumarin drugs.

It is given orally, and it acts within two days.

Uses

Dicoumarol was used, along with heparin, for the treatment of deep venous thrombosis. Unlike heparin, this class of drugs may be used for months or years.

Mechanism of action

Like all 4-hydroxycoumarin drugs it is a
