A colourless crystalline compound used to help prevent the blood clotting.
Anticoagulant used to prevent and treat thrombosis and embolism. Adverse effects include hemorrhage and the possibility of interaction with many other drugs.
An anticoagulant drug. Warfarin (Coumadin) is used to prevent blood clots. It is also used to prevent or treat blood clots that may form in a blood vessel or in the lungs. It may be prescribed to prevent blood clots associated with certain heart conditions or to people with a heart valve replacement. Warfarin may be used after a heart attack to prevent blood clots from forming anywhere in the body. Warfarin can reduce the risk of death, another heart attack, or a stroke following a heart attack.
An anticoagulant used mainly in the treatment of coronary or venous thrombosis to reduce the risk of embolism. It is given by mouth or injection. The principal toxic effect is local bleeding, usually from the gums and other mucous membranes. Warfarin has also been used as a rat poison.
An anticoagulant, usually given by mouth on a daily basis. It is indicated for the prophylaxis of embolization in rheumatic heart disease and atrial fibrillation; after prosthetic heart-valve insertion; prophylaxis and treatment of venous thrombosis and pulmonary embolism; and transient Ischaemic attacks or episodes (TIA, TIE). The initial dose depends upon the prothrombin or coagulation time; this should be determined before starting treatment, and then at regular intervals during treatment, as the dose needed may alter from time to time. This monitoring may be performed within a general practice. When given in tablet form, its maximum effect generally occurs within about 36 hours, wearing off within 48 hours. Special caution is appropriate in patients with disease of the liver or kidneys or who have had recent surgery. Warfarin should not be used during pregnancy (especially the first and third trimesters), and in cases of peptic ulcer, severe hypertension and bacterial endocarditis. The most important adverse effect is haemorrhage. Other reported side-effects include hypersensitivity, rash, alopecia, diarrhoea, unexplained drop in haematocrit readings, purple toes, skin necrosis, jaundice, liver dysfunction, nausea, vomiting and pancreatitis.
A medication or anticoagulant employed to prevent the formation of blood clots. Its function is assessed through PT tests, which help monitor its effectiveness.
Warfarin is an anticoagulant medication employed to prevent and manage abnormal blood clot formation. It is used to address conditions such as deep vein thrombosis (the formation of blood clots within the deep veins of the leg), pulmonary embolism (when a fragment of a blood clot becomes lodged in the lungs during circulation), and individuals with atrial fibrillation (a heart rhythm abnormality) who are at risk of experiencing an embolism. Additionally, it is prescribed to deter the development of emboli on replacement heart valves.
In the initial days following a diagnosis of deep vein thrombosis or pulmonary embolism, a more rapidly acting anticoagulant, like heparin, may be recommended.
Warfarin has the potential to induce abnormal bleeding in various body regions, necessitating regular testing to precisely adjust the dosage. It can also lead to side effects such as nausea, diarrhea, and skin rashes.
