Toxicity Profile
Route of ExposureOral (ingestion) (3) ; dermal (3)
Mechanism of ToxicityBrodifacoum inhibits the enzyme Vitamin K epoxide reductase. This enzyme is needed for the reconstitution of the vitamin K in its cycle from vitamin K-epoxide, and so brodifacoum steadily decreases the level of active vitamin K in the blood. Vitamin K is required for the synthesis of important substances including prothrombin, which is involved in blood clotting. This disruption becomes increasingly severe until the blood effectively loses any ability to clot. In addition, brodifacoum increases permeability of blood capillaries. The blood plasma and blood itself begins to leak from the blood vessels, causing internal bleeding leading to shock, loss of consciousness, and eventually death. (2)
MetabolismNot Available
Toxicity ValuesLD50: 0.4 mg/kg (Oral, Mouse) (1)
Lethal Dose15 mg for an adult human. (2)
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesBrodifacoum is a highly lethal anticoagulant poison used as a pesticide. It is typically used as a rodenticide but is also used to control larger mammalian pests. (2)
Minimum Risk LevelNot Available
Health EffectsBrodifacoum is an anticoagulant and causes internal bleeding, leading to shock, loss of consciousness, and eventually death. (2)
SymptomsBrodifacoum initially causes dehydration before progressing to bleeding complications. (2)
TreatmentThe primary antidote to brodifacoum poisoning is immediate administration of vitamin K1 (initially slow intravenous injections of 10-25 mg repeated all 3-6 hours until normalisation of the prothrombin time; then 10 mg orally four times daily as a "maintenance dose"). It is an extremely effective antidote, provided the poisoning is caught before too much damage has been done to the victim's circulatory system. At high doses brodifacoum can affect the body for many months, and the antidote must be administered regularly for a long period of time. (2)

Targets

Target Details
1. Vitamin K epoxide reductase complex subunit 1
General Function:
Vitamin-k-epoxide reductase (warfarin-sensitive) activity
Specific Function:
Involved in vitamin K metabolism. Catalytic subunit of the vitamin K epoxide reductase (VKOR) complex which reduces inactive vitamin K 2,3-epoxide to active vitamin K. Vitamin K is required for the gamma-carboxylation of various proteins, including clotting factors, and is required for normal blood coagulation, but also for normal bone development.
