Expert

Verified

Dicoumarol is an anticoagulant drug. Due to its molecular structure dicoumarol competes with vitamin K for the binding to substrates blocking the formation of clotting factors and interrupting the making of prothrombin.

Dicoumarol is found in a few vegetables undergoing decomposition, and it can cause severe internal hemorrhages when those vegetables are accidentally ingested. Coumarinic anticoagulants can’t be administered throughout pregnancy since they pass the placental barrier and can cause fetal hemorrhages.
