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]
If the dosage guidelines are followed, the drug reaches peak plasma levels after two hours and is completely cleared from plasma two hours after termination of the infusion period. [citation needed] Endogenous plasma protease inhibitors deactivate drotrecogin. Therefore, no dose adjustment is needed in elderly patients, or in patients with ...
Apart from using unfractionated heparin instead, it may be possible to reduce the dose and/or monitor the anti-Xa activity to guide treatment. [3] The most common side effects include bleeding, which could be severe or even fatal, allergic reactions, injection site reactions, and increases in liver enzyme tests, usually without symptoms. [13]
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 ...
For anticoagulant treatment, it is not clear if unfractionated and/or low molecular weight heparin treatment is effective at decreasing mortality and serious adverse events in this population. [19] There is also insufficient evidence to understand the risk of adverse effects associated with these treatment approaches in term or preterm infants ...
Protamine sulfate is a medication that is used to reverse the effects of heparin. [3] It is specifically used in heparin overdose, in low molecular weight heparin overdose, and to reverse the effects of heparin during delivery and heart surgery. [3] [4] It is given by injection into a vein. [3] The onset of effects is typically within five ...
It is thought that much protein interaction with heparin is not direct, and instead heparin binding protein actually interact with glycosaminoglycan (GAG) side chains or mucins bound to the heparin polymer, so it is possible that heparinoids interact with these proteins in a similar way, acquiring GAG side chains in vivo.
Danaparoid is used for thrombosis prophylaxis and treatment in heparin-induced thrombocytopenia patients. Although pre-treatment serological cross-reactivity with heparin-induced antibodies can occur in 5.2% of the patients it bears no systematic relationship with clinical cross-reactivity, 3.2% in the same study of 1478 patients with acute HIT ...
