Flocoumafen is a fluorinated, second-generation anticoagulant of the 4-hydroxycoumarin vitamin K antagonist type.^[1] It is a second generation (i.e., high potency) chemical in this class, used commercially as a rodenticide. It has a very high toxicity and is restricted to indoor use and sewers (in the UK). This restriction is mainly due to the increased risk to non-target species, especially due to its tendency to bio-accumulate in exposed organisms. Studies have shown that rodents resistant to first-generation anticoagulants can be adequately controlled with flocoumafen.^[1] It was synthesized in 1984 by Shell International Chemical.^[2]

Toxicityedit

In most rodents, the LD₅₀ is 1 mg/kg, but it can vary between species: from 0.12 mg/kg in the common vole (Microtus arvalis) to more than 10 mg/kg in the Cairo spiny mouse (Acomys cahirinus). For dogs the LD₅₀ is 0.075-0.25 mg/kg.^[2]

Antidoteedit

The antidote to flocoumafen is vitamin K₁, which must be administered over a period of several weeks or even months.^[3]
