2024年6月6日 · One of the main differences between the two types of heparins is how you get them. You get UFH through an IV, usually at a hospital, but you can inject yourself with LMWH …

Both unfractionated heparin (UFH) and low-molecular-weight heparins (LMWHs) have established roles in preventing and treating venous thromboembolism (VTE) and as adjuvant therapies for atherothrombotic syndromes. 1,2 Numerous studies have compared the efficacy and safety of …

2023年4月3日 · Low Molecular-Weight Heparin (LMWH) is a heterogeneous collection of heparin molecules with a lower average molecular weight compared to unfractionated heparin. Since longer length is necessary to facilitate the interaction between antithrombin III and factor IIa, LMWH is less effective at inhibiting factor IIa (acting mostly via inhibition of Xa).

2016年8月25日 · Most trauma programs tend toward using low molecular weight heparin (LMWH) products for VTE prophylaxis over plain, old-fashioned unfractionated heparin (UH). How did this happen? LMWH is more expensive than UH, and there is …

2017年5月1日 · LWMH has a number of benefits over UH. LMWH can be given in once or twice daily regimes without the need for activated partial thromboplastin time ratio (APTR) titration or a continuous intravenous infusion that is needed with UH.

The effects of low-molecular-weight heparin (LMWH) vs unfractionated heparin (UFH) in the acute treatment of venous thromboembolism.

Conclusions: LMWHs, as a class of drugs, are no more predictable in antithrombin effect after subcutaneous injection than unfractionated heparin. There were considerable differences among LMWHs in the observed variability of antithrombin effects, with tinzaparin being somewhat more predictable than the other drugs tested.

Low molecular weight heparins (LMWH) have emerged as an important alternative to unfractionated heparin (UH) for both prophylaxis and treatment of venous thromboembolism (VTE) in acutely ill medical patients.1 Clinical studies2-5 show that LMWH given once or twice a day is as effective and safe as UH, and may be superior to UH.

2000年10月15日 · In many countries, low molecular weight heparins (LMWHs) have replaced unfractionated heparin (UH) for prevention and treatment of venous thromboembolism. The present paper reviews the possible advantages of LMWHs over UH. In spite of their lower molecular weight distribution, LMWHs are functionally more heterogeneous than UH.

The use of LMWH has potential advantages in comparison with the use of standard unfractionated heparin (UH), including decreased binding to nonanticoagulant-related plasma proteins, greater bioavailability, longer half-life, and lower incidence of the heparin-induced thrombocytopenia syndrome.
