Warfarin Usage And Synthesis

Application in Ischemic Stroke	aaa3
Application in Ischemic Stroke	Warfarin is the antithrombotic agent of first choice for secondary prevention in patients with atrial fibrillation and a presumed cardiac source of embolism.
Description	Warfarin is tasteless and colorless. It is a widely used as anticoagulant (which stops the blood clotting) in the treatment and prevention of thrombosis, in the treatment for chronic atrial fibrillation, mechanical valves, pulmonary embolism, and dilated cardiomyopathy. Warfarin is metabolized primarily via oxidation in the liver by CYP2C9, and exerts its anticoagulant effect by inhibiting the protein vitamin K epoxide reductase complex, subunit 1 (VKORC1). Warfarin therapy can be associated with significant bleeding complications. Achieving a safe therapeutic response can be difficult because of warfarin’s narrow therapeutic index and great individual variability in the dose required, which is mostly a consequence of individual genetic variants: it is influenced by ageing, co-prescribed drugs, diet, alcohol consumption, and comorbid conditions. To maintain a therapeutic level of anti-thrombosis and to minimize the risk of bleeding complications, warfarin therapy requires intensive monitoring via the INR to guide its dosing. It is also used as the first generation of anticoagulant rodenticides.

Application	Warfarin is an anti-coagulant used to prevent heart attacks, strokes, and the formation of blood clots. It interferes with the use of vitamin K in the required carboxylation of several vitamin K-dependent proteins in the clotting cascade, preventing the initiating of clotting. (±)-Warfarin is a racemic mixture of 2 optically active isomers. (±)-Warfarin has a half-life of 36-42 hours in circulation, bound to plasma proteins, and accumulates in the liver, where the two isomers are metabolized by different pathways.
General Description	Odorless and colorless solid. Used as a rodenticide for Norway rats and for house mice.
Reactivity Profile	Warfarin is incompatible with the following: Strong oxidizers .
Health Hazard	Warfarin is classified as very toxic. Probable oral lethal dose in humans is 50-500 mg/kg, between 1 teaspoon and 1 ounce for a 150 lb. person. Material is an anticoagulant. Toxic effects other than hemorrhage are rarely seen in humans. Material is believed to be teratogenic in humans. Persons with a history of blood disorders with bleeding tendencies would be expected to be at increased risk from exposure.
Fire Hazard	Contact with strong oxidizers may cause fires and explosions. Toxic gases and vapors (e.g., carbon monoxide) may be released in heating to decomposition. Avoid strong oxidizers.
Agricultural Uses	Rodenticide: Warfarin and its sodium salt is an anticoagulant rodenticide used for controlling rats and house mice in and around homes, animal and agricultural premises, and commercialand industrial sites. It is effective in very low dosages. About a week is required before a marked reduction in the rodent population is noticeable. Rodents do not become bait-shy after once tasting warfarin; they continue to consume it until its anti-clotting properties have produced death through internal hemorrhaging. It can be used year-after-year wherever a rodent problem exists. Warfarin and its sodium salt are only slightly dangerous to humans and domestic animals when used as directed, but care must be taken with young pigs, which are especially susceptible. The sodium salt is also used to treat people with blood hypercoagulation problems. Registered for use in EU countries . Registered for use in the U.S.
