DictionarySeeanticoagulantMedicalSeeANTICOAGULATION: Bruising and bleeding, common side effects of anticoagulation.2. An agent that prevents or delays blood coagulation. Common anticoagulants include heparin, sodium citrate, and warfarin sodium. See: illustrationcoumarin anticoagulantAny of a group of natural and synthetic compounds that inhibit blood clotting by antagonizing the biosynthesis of vitamin K–dependent coagulation factors in the liver. See: dicumarol; warfarin sodiumwarfarin sodium anticoagulant See: warfarin sodiumanticoagulant A drug used to limit the normal clotting processes of the blood. Anticoagulants are used in conditions in which dangerous clots can form in blood vessels. Anticoagulant drugs include HEPARIN, LOW MOLECULAR WEIGHT HEPARIN and WARFARIN. Anticoagulant treatment carries its own dangers, specifically those related to internal bleeding. The principal danger is of bleeding within the skull and resultant STROKE. The danger is greatest in elderly people with high blood pressure. This may be spontaneous or may follow quite minor trauma to the head. Careful control of dosage with regular blood checks of PROTHROMBIN TIME, and the avoidance of head injury, minimize the risk.anticoagulant a substance that hinders AGGLUTINATION or clotting of blood cells. BLOOD CLOTTING is a vital reaction to damage in the circulatory system, one of the steps in the process being dependent on the presence of calcium ions. However, the tendency of blood to clot can be overcome by suitable chemicals that remove calcium, such chemicals being used as anticoagulants when storage of blood is required. Many bloodsucking parasites such as mosquitoes secrete anticoagulants into the host's bloodstream, so enabling blood to be easily transported into the parasite's digestive system.AnticoagulantDrug used to prevent clot formation or to prevent a clot that has formed from enlarging. Anticoagulant drugs inhibit clot formation by blocking the action of clotting factors or platelets. Anticoagulant drugs fall into three groups: inhibitors of clotting factor synthesis, inhibitors of thrombin and antiplatelet drugs.Mentioned in: Anticoagulant and Antiplatelet Drugs, Leeches, Myocardial Biopsyan·ti·co·ag·u·lant (an'tē-kō-ag'yŭ-lănt) An agent that prevents coagulation (e.g., warfarin).
