Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. [3] [4] Heparin is a blood anticoagulant that increases the activity of antithrombin. [5] It is used in the treatment of heart attacks and unstable angina. [3] It can be given intravenously or by injection under the skin. [3]
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.
Dalteparin is a low molecular weight heparin.It is marketed as Fragmin.Like other low molecular weight heparins, dalteparin is used for prophylaxis or treatment of deep vein thrombosis and pulmonary embolism to reduce the risk of a stroke or heart attack. [2]
Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia ... Gradually, evidence accumulated on the exact underlying mechanism. [4]
Heparinoids, like heparin, act by interacting with heparin binding proteins, generally through ionic interactions or hydrogen bonding. Some examples of heparin binding proteins include antithrombin III. It is thought that much protein interaction with heparin is not direct, and instead heparin binding protein actually interact with ...
The PF4-heparin complex can activate platelets and may cause venous and arterial thrombosis. [8] When lepirudin binds to thrombin it hinders its prothrombic activity. [16] Three prospective studies, called the Heparin-Associated-Thrombocytopenia (HAT) 1,2, and 3, were performed that compared lepirudin with historical controls in the treatment ...
Idraparinux sodium is an anticoagulant medication in development by Sanofi-Aventis. [1]It has a similar chemical structure and the same method of action as fondaparinux, but with an elimination half-life about five to six times longer (an increase from fondaparinux's 17 hours to approximately 80 hours), which means that the drug should only need to be injected once a week.
Fondaparinux is a synthetic pentasaccharide factor Xa inhibitor. Fondaparinux binds antithrombin and accelerates its inhibition of factor Xa.. Apart from the O-methyl group at the reducing end of the molecule, the identity and sequence of the five monomeric sugar units contained in fondaparinux is identical to a sequence of five monomeric sugar units that can be isolated after either chemical ...
