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]
Average molecular weight: heparin is about 15 kDa, and LMWH is about 4.5 kDa. [25] Less frequent subcutaneous dosing than for heparin for postoperative prophylaxis of venous thromboembolism. Once or twice daily subcutaneous injection for treatment of venous thromboembolism and in unstable angina instead of intravenous infusion of high-dose heparin.
Subcutaneous administration is the insertion of medications beneath the skin either by injection or infusion. A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. The instruments are usually a hypodermic needle and a syringe.
As they are administered by injection (intravenous, intramuscular or subcutaneous), they are less suitable for long-term treatment. [ 1 ] Argatroban (as well as the hirudins) is used for heparin-induced thrombocytopenia , a relatively infrequent yet serious complication of heparin treatment that requires anticoagulation (as it increases both ...
While heparin was introduced for clinical use in the late 1930s, new thrombosis in people treated with heparin was not described until 1957, when vascular surgeons reported the association. [ 4 ] [ 16 ] The fact that this phenomenon occurred together with thrombocytopenia was reported in 1969; [ 17 ] prior to this time, platelet counts were not ...
Fresh normal plasma has all the blood coagulation factors with normal levels. If the problem is a simple factor deficiency, mixing the patient plasma 1:1 with plasma that contains 100% of the normal factor level results in a level ≥50% in the mixture (say the patient has an activity of 0%; the average of 100% + 0% = 50%). [3]
An anticoagulant, commonly known as a blood thinner, is a chemical substance that prevents or reduces the coagulation of blood, prolonging the clotting time. [1] Some occur naturally in blood-eating animals, such as leeches and mosquitoes, which help keep the bite area unclotted long enough for the animal to obtain blood.
Argatroban is an anticoagulant that is a small molecule direct thrombin inhibitor. [3] In 2000, argatroban was licensed by the US Food and Drug Administration (FDA) for prophylaxis or treatment of thrombosis in people with heparin-induced thrombocytopenia (HIT).
