Heparin cofactor

Heparin cofactor refers to a specific molecule, called antithrombin, that enhances the blood-thinning effects of the medication heparin. When heparin is present, antithrombin's activity increases, helping it to inactivate enzymes involved in blood clot formation, particularly thrombin and factor Xa. This process helps prevent excessive clotting and reduces the risk of blood clots forming in veins or arteries. Essentially, heparin cofactor (antithrombin) acts as a natural partner that boosts heparin's ability to stop unwanted blood clots, maintaining proper blood flow and preventing complications like deep vein thrombosis or pulmonary embolism.
