Warfarin is indicated for the prophylaxis and treatment of venous thrombosis and its extension, pulmonary embolism; [9] prophylaxis and treatment of thromboembolic complications associated with atrial fibrillation and/or cardiac valve replacement; [9] and reduction in the risk of death, recurrent myocardial infarction, and thromboembolic events such as stroke or systemic embolization after ...
In enzymology, a vitamin-K-epoxide reductase (warfarin-sensitive) (EC 1.17.4.4) is an enzyme that catalyzes the chemical reaction 2-methyl-3-phytyl-1,4-naphthoquinone + oxidized dithiothreitol ⇌ {\displaystyle \rightleftharpoons } 2,3-epoxy-2,3-dihydro-2-methyl-3-phytyl-1,4-naphthoquinone + 1,4-dithiothreitol
Warfarin resistance is a rare condition in which people have varying degrees of tolerance to the anticoagulant drug warfarin.In incomplete warfarin resistance, people only respond to high doses of warfarin; in complete warfarin resistance, the drug has no effect.
If these patients are prescribed warfarin for another medical purpose, they will require lower doses than usual because the patient is already deficient in VKORC. They may experience severe bleeding and bruising. Lower warfarin doses are needed to inhibit VKORC1 and to produce an anticoagulant effect in carriers of the A allele.
Since a low therapeutic index indicates that there is a high risk of toxicity when using the drug, any potential increases in warfarin concentration could be very dangerous and lead to hemorrhage. In horses, it is very true that if warfarin and phenylbutazone are administered concurrently, the horse can develop bleeding issues which can be ...
Low-molecular-weight heparin (LMWH) is a class of anticoagulant medications. [1] They are used in the prevention of blood clots and, in the treatment of venous thromboembolism (deep vein thrombosis and pulmonary embolism), and the treatment of myocardial infarction.
Warfarin – a coumarin – with brand name, Coumadin, is a prescription drug used as an anticoagulant to inhibit formation of blood clots, and so is a therapy for deep vein thrombosis and pulmonary embolism. [9] [10] [11] It may be used to prevent recurrent blood clot formation from atrial fibrillation, thrombotic stroke, and transient ...
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
