Warfarin is a synthetic derivative of dicoumarol, and since 1948 has had a major role in slaughtering rats and mice by stimulating internal bleeding. In 1954, warfarin was also approved for therapeutic use as an anticoagulant in the prevention of thrombosis and thromboembolism.Is warfarin the same thing as rat poison?
The chemicals in question are anticoagulant rodenticides (ARs), which work like the human blood-thinning drug warfarin. Warfarin is itself used as a rat poison, but is what environmental toxicologists call a first-generation AR, less lethal and less prone to bioaccumulation than its second-generation successors.How does warfarin work as a rat poison?
This protein is involved in recycling the vitamin K that is used in the clotting process so that it can be used again. Warfarin reduces the amount of vitamin K in the bloodstream by inhibiting this enzyme, thereby slowing down the action of several clotting factors that depend on vitamin K.

Dr. Jared Bunch, the lead researcher on the study, said the findings uncover two potential concerns: People with atrial fibrillation may face an increased risk of dementia, independent of warfarin use, but warfarin might also contribute to dementia if the doses are not optimal.Can you eat cheese on warfarin?

Basically mice have a genetic mutation to be immune to warfarin. The mutation to vkorc1, a gene found in all mammals that manages vitamin K, makes mice resistant to the anticoagulant.
