Bromadiolone can be absorbed through the digestive tract, through the lungs, or through skin contact. Links to world-wide registration status as well as regulatory information for the U.S. and California. The slow disappearance from the plasma and liver and the large liver/serum ratio probably contribute to the higher toxicity of brodifacoum compared to warfarin. Anticoagulants vary in toxicity to non-target species. Toxicol Rev. Second-generation anticoagulants: brodifacoum, bromadiolone, difenacoum, and difethialone. Clipboard, Search History, and several other advanced features are temporarily unavailable. Toxicity Level Most of us are used to dealing with anticoagulants; it generally does not take a lot of an anticoagulant to cause problems in our patients, and luckily there is an effective antidote. NLM Kinetics and metabolism in laboratory animals and, 2.6. The “first generation” chemicals such as warfarin require multiple ingestions of bait to result in toxicity, while anticoagulants like chlorophacinone and diphacinone are more toxic and require fewer feedings to … 4. Sources of human and environmental exposure, 2.3. Bochner R. [National Poisoning Information System - SINITOX and human intoxication by pesticides in Brazil]. Disappearance from serum is slow, with a half-life of 156 h or even more. Regardless of the brand, they contain one of these strongest rat and mouse poisons – Difethialone, Bromadiolone, Brodifacoum. Brodifacoum has an especially long half-life in the body, which ranges up to nine months, requiring prolonged treatment with antidotal vitamin K for … Common anticoagulant rodenticides include warfarin, diphacinone, chlorphacinone, brodifacoum, difenacoum, and bromadiolone. Main human health hazards, prevention and protection, 5. 1993 Aug 23;153(16):1925-8. Exposures and intoxications can affect humans, domestic animals and wildlife. Subsequently plasma concentrations of difenacoum and … For more Human Toxicity Excerpts (Complete) data for DIFENACOUM (14 total), please visit the HSDB record page. European countries have registered this rodenticide since the 1970's. Evaluation of effects on the environment, 3.2. CURRENT REGULATIONS, GUIDELINES, AND STANDARDS, 7.1. SUMMARY OF CHEMICAL SAFETY INFORMATION, 7. Difenacoum is a 2nd generation anticoagulant rodentcide that is not approved for use in many countries. HHS COVID-19 is an emerging, rapidly evolving situation. Effects on laboratory mammals and in vitro test systems, 2.8. Eleven cases (7 children, 1 teenager, and 3 adults) satisfied the criteria of superwarfarin exposure or poisoning. It is an odorless powder that is white to yellow in color. Acute toxicity of difenacoum to aquatic invertebrates. The EPA will also ban the sale of some of the more toxic chemicals to residential consumers; banned chemicals will include brodifacoum, bromadiolone, difethialone, and difenacoum. The patient continued to have episodes of epistaxis, haematoma, purpurae and bruising and he required frequent treatment with Fresh Frozen Plasma in additional to oral phylloquinone (200 mg day-1). H300: Fatal if swallowed [Danger Acute toxicity, oral] H310: Fatal in contact with skin [Danger Acute toxicity, dermal] H330: Fatal if inhaled [Danger Acute toxicity, inhalation] H360D: May damage the unborn child [Danger Reproductive toxicity] Treatment for long acting anticoagulant rodenticide poisoning - beyond INR monitoring? As a technical material, difenacoum is highly to extremely toxic for various mammalian species. Ng WY, Ching CK, Chong YK, Ng SW, Cheung WL, Mak TWL. The substance is a vitamin K antagonist. Non-anticoagulants: bromethalin, cholecalciferol and zinc phosphide. Brodifacoum, one of the “second-generation antico-agulants,” is much more toxic, partly due to a longer half-life; a dose as low as 1 mg in an adult or 0.014 mg/kg in … Environmental levels and human exposure, 2.5.

Brodifacoum should not be hazardous to humans, pets, or wildlife as long as it is used and applied according to the product label. A longitudinal toxicological study of the consequent coagulopathy is described. Arch Intern Med. It should be handled carefully and as directed. Rodenticides are pesticides that kill rodents. In recent years, it has become one of the world's most widely used pesticides. In some regions, including the United States, this toxicity is denoted by signal words on product labels: danger, warning, and caution. The acute toxicity reported on this page is of the pure chemical ingredient only and may not reflect the acute toxicity of individual pesticide products. Prolonged treatment with high doses of vitamin K and/or fresh frozen plasma (FFP) transfusions may be necessary. NIH The measurement of low concentrations of plasma phylloquinone except following supervised ingestion of the vitamin indicated that as an outpatient, the subject was not compliant with treatment despite his protestations to the contrary. The coumarin anticoagulant difenacoum was detected by high performance liquid chromatography (HPLC) with multi-wavelength UV detection in plasma from a 41 years old man who presented with a severe deficiency of vitamin K-dependent clotting factors of unknown aetiology. They include brodifacoum, bromadiolone, chlorophacinone, coumafuryl, difenacoum, difethialone, and diphacinone. The lack of vitamin K in the circulatory system reduces blood clotting and will cause death due to internal hemorrhaging. The first occurs at high doses (at or above the LD 50) and is characterized by an acute syndrome occurring within 24 hours post exposure. Brodifacoum has a half life of 157 days, causing it to remain active for several months. 2. Second-generation compounds are now more commonly encountered in veterinary exposures. Toxicity: Bromethalin is a somewhat slow acting, progressive neurotoxin. The pesticide is generally given orally. It is considered to be only of low acute toxicity to humans because of its low bait concentration and delayed effect. doi: 10.5830/CVJA-2012-051. Environmental transport, distribution, and transformation, 2.4. Regulatory. Second-generation anticoagulant rodenticides were developed and are far more toxic than the first-generation anticoagulant compounds. Retrospective Study of the Characteristics of Anticoagulant-Type Rodenticide Poisoning in Hong Kong. Plasma concentrations of difenacoum declined from 0.97 to 0.11 mgl-1 in 47 days with a terminal half life of 11.7 days. Table 14. Difenacoum poisoning as a cause of haematuria. and difenacoum, may cause serious poisoning of non-target mammals, including humans, at much lower dosage. 2018 Sep;14(3):218-228. doi: 10.1007/s13181-018-0660-x. 12 (1):73-89. .
