A glycosaminoglycan that is attached to a core protein found in mast cells; anticoagulant activity; serves as a catalyst for antithrombin attachment to thrombin.
A polysaccharide sulfuric acid ester found in liver, lung, and other tissues that prolongs the clotting time of blood by preventing the formation of fibrin. Used in vascular surgery and in treatment of postoperative thrombosis and embolism.
A substance obtained from the liver that inhibits blood clotting.
An anticoagulant substance found in the liver and lungs, and also produced artificially for use in the treatment of thrombosis.
A mucopolysaccharide used in the prevention and treatment of thrombosis and embolism and as an anticoagulant.
Chemical produced in certain white blood cells (basophils) and connective tissue cells (mast cells), especially in the lungs and liver, that inhibits the activity of the thrombin factor in blood coagulation and thus prevents clotting within the blood vessels.
An anticoagulant drug used to prevent formation of blood clots in blood vessels. Heparin works by interfering with the blood clotting process specifically by accelerating the natural anticlotting process.
An anticoagulant produced in liver cells, some white blood cells, and certain other sites, which acts by inhibiting the action of the enzyme thrombin in the final stage of blood coagulation. An extracted purified form of heparin is widely used for the prevention of blood coagulation both in patients with thrombosis and similar conditions and in blood collected for examination. The drug is usually administered by injection and the most important side-effect is bleeding.
Heparin is a naturally produced anticoagulant with a rapid effect, which is thought to act by neutralizing thrombin. Inactive when taken orally, it is normally given intravenously — it may be given for a few days, combined with an oral anticoagulant such as warfarin, to initiate anticoagulation. Lowdose heparin may be given by subcutaneous injection for longer periods, for the prophylaxis of deep vein thrombosis (DVT) or pulmonary embolism in ‘high-risk’ patients, such as those with obesity or a history of thrombosis, or post-operatively. If haemorrhage occurs, withdrawal of heparin is usually sufficient, but protamine sulphate is a rapidly active and specific antidote. Prolonged treatment with heparin may cause osteoporosis.
A parenteral anticoagulant drug with a faster onset than warfarin or its derivatives. It is composed of polysaccharides that inhibit coagulation by forming an antithrombin that prevents conversion of prothrombin to thrombin and by preventing liberation of thromboplastin from platelets. Because heparin is poorly absorbed from the gastrointestinal tract, it is usually administered intravenously or subcutaneously as a sodium or calcium salt.
A blood constituent responsible for regulating clotting levels. It can be utilized as a medication to diminish the formation of blood clots.
Heparin is an anticoagulant drug utilized to prevent and treat abnormal blood clotting. It is administered through injections and serves as an immediate treatment for conditions like deep vein thrombosis or pulmonary embolism. Moreover, it can be prescribed as a preventive measure for individuals who are immobilized due to illness or surgery. Nowadays, low molecular weight heparins, such as tinzaparin, are widely employed, requiring only once-a-day injections, and they can be self-administered at home.
Heparin can lead to adverse effects, such as skin rashes, bone aches, and abnormal bleeding in various body regions. Prolonged use of heparin may also result in osteoporosis.
A compound present in the liver and various tissues that inhibits blood clotting and the development of blood platelets. It is employed as an anticoagulant to manage conditions like coronary thrombosis and is presently obtained from animal livers and lungs.
