Brodifacoum

From WikiMD's Wellnesspedia

Brodifacoum is a highly lethal rodenticide that is used globally to control rodent populations. It is a member of the 4-hydroxycoumarin anticoagulant drug class, which also includes other rodenticides such as flocoumafen, bromadiolone, and difethialone.

Chemistry[edit | edit source]

Brodifacoum has a complex chemical structure. It is a derivative of 4-hydroxycoumarin, with a 3-(3-(4'-bromobiphenyl-4-yl)-1,2,3,4-tetrahydronaphthalen-1-yl)-4-hydroxycoumarin structure. This structure is responsible for its anticoagulant properties.

Mechanism of Action[edit | edit source]

Brodifacoum inhibits the enzyme vitamin K epoxide reductase. This enzyme is necessary for the reactivation of vitamin K, which is a cofactor for the synthesis of important blood clotting factors in the liver, including Prothrombin (Factor II), Factor VII, Factor IX, and Factor X. The inhibition of this enzyme leads to the depletion of active vitamin K in the blood, which in turn leads to a disruption in blood clotting.

Toxicity[edit | edit source]

Brodifacoum is highly toxic to mammals and birds, and it is especially lethal to rodents. It is a single-feed anticoagulant, which means that a single ingestion of the poison is enough to cause death. The symptoms of brodifacoum poisoning include bleeding gums, bloody nose, blood in urine or feces, and internal bleeding.

Treatment[edit | edit source]

Treatment for brodifacoum poisoning involves discontinuing exposure to the poison, administering vitamin K1 therapy, and providing supportive care. In severe cases, blood transfusions may be necessary.

Environmental Impact[edit | edit source]

Brodifacoum is persistent in the environment and can cause secondary and tertiary poisoning, and it poses a significant risk to endangered wildlife. It is classified as a Persistent Organic Pollutant (POP) due to its high toxicity, long half-life, and potential for bioaccumulation and biomagnification.
