WebHeparin is a medication that inhibits clotting by activating your body's anti-clotting processes. One of the anticlotting processes uses a type of blood protein called antithrombin. Heparin works by activating antithrombin, and then antithrombin keeps other parts of the clotting process from working normally. WebHeparin is a polysaccharide consisting of a pentasaccharide sequence. The numerous sulfate groups on glucosamine residues result in a strong negative charge density. This strong negative charge density of heparin molecules is …

WebHeparin is commonly used in the management of coronary artery disease, deep vein thrombosis, pulmonary embolism, and atrial fibrillation, and in the prevention of thrombosis during cardiopulmonary bypass and extracorporeal membrane oxygenation. Heparin treatment is a key component in elective percutaneous coronary intervention (PCI).
Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan. Since heparins depend on the activity of antithrombin, they are considered anticoagulants. Specifically it is also used in the treatment of heart attacks and unstable angina.
