Unfractionated vs. Low-Molecular-Weight Heparin for DVT - WebMD
2024年6月6日 · Two types of heparins are commonly used for DVT: unfractionated heparin (UFH) and low-molecular-weight heparin (LMWH). The two types of heparin work in a similar way. They don’t destroy...

2023年4月3日 · Unfractionated heparin (UFH) binds to antithrombin III (AT-III), which enhances antithrombin's inhibition of several coagulation factors – especially factor Xa and factor IIa (thrombin). Low Molecular-Weight Heparin (LMWH) is a heterogeneous collection of heparin molecules with a lower average molecular weight compared to unfractionated heparin.
List of Heparins - Drugs.com
Heparin is an injectable anticoagulant that activates antithrombin III, which inhibits thrombin and factor Xa, factors necessary in the final stages of blood clotting cascade. There are two types of heparins: high molecular weight heparins and low molecular weight heparins.
A Review of Unfractionated Heparin and Its Monitoring - U.S. Pharmacist
2007年7月13日 · UFH produces its major anticoagulant effect by inactivating thrombin and activated factor X (factor Xa) through an antithrombin-dependent mechanism. UFH binds to antithrombin through a high-affinity pentasaccharide, leading to a conformational change.

Unfractionated Heparin and Low-Molecular Heparins
Unfractionated heparin (UFH) is considered an indirect parenteral anticoagulant, as it has little or no intrinsic anticoagulant activity and works by potentiating the effect of antithrombin (AT), by UFH binding to it, and thereby inhibiting various activated clotting factors. 1
Unfractionated heparin (UFH) acts as an anticoagulant by forming a complex with antithrombin (AT) catalysing the inhibition of several activated blood coagulation factors: thrombin (factor IIa), factor IXa, Xa, XIa and XIIa. This prevents fibrin formation and inhibits thrombin-induced activation of platelets and factors V, VIII, and XI.
Low-Dose Unfractionated Heparin - SCIRE Professional
Unfractionated heparin has been the standard treatment for VTE post SCI for years. Evidence for its effectiveness, however, is unclear. Using LDUH alone is not recommended as a prophylactic treatment (Dhall et al. 2013) and is associated with high rates of DVTs and PEs in individuals with acute SCI (Kulkarni et al. 1992).

Unfractionated and low molecular weight heparin - PMC
Unfractionated heparin (UFH) is mostly obtained from porcine and bovine mucosa and has been widely used for the treatment and prevention of thrombotic events. It consists of molecular chains of various lengths varying from 2000 to 40,000 Da [1].
