Inhibition of Plasmin Generation in Plasma By Heparin, Low Molecular Weight Heparin and a Covalent Antithrombin-Heparin Complex (ATH)

Low Molecular Weight Heparin Overdose: A 10 Year Case Series

  Background: Low molecular weight heparin (LMWH) is used for the treatment and prevention of coagulative disorders. Few patients receiving therapeutic doses of LMWH develop major hemorrhage. Currently there are few reports in the literature on acute overdose on adults.  In this study, clinical profile, treatment and outcome of 21 patients who acutely overdosed enoxaparin are described. Method...

Heparin and low-molecular-weight heparin.

Heparin is one of the oldest biological medicines, and has an established place in the prevention and treatment of venous thrombosis. Low-molecular-weight heparins (LMWH) have been developed by several manufacturers and have advantages in terms of pharmacokinetics and convenience of administration. They have been shown to be at least as effective and safe as unfractionated heparin and have repl...

Heparin mapping using heparin lyases and the generation of a novel low molecular weight heparin.

Seven pharmaceutical heparins were investigated by oligosaccharide mapping by digestion with heparin lyase 1, 2, or 3, followed by high performance liquid chromatography analysis. The structure of one of the prepared mapping standards, ΔUA-Gal-Gal-Xyl-O-CH(2)CONHCH(2)COOH (where ΔUA is 4-deoxy-α-l-threo-hex-4-eno-pyranosyluronic acid, Gal is β-d-galactpyranose, and Xyl is β-d-xylopyranose) rele...

Inhibition of trypsin by heparin and dalteparin, a low molecular weight heparin

The interaction between trypsin, a prototype S1 serine protease, with heparin and its low molecular weight derivative dalteparin were investigated. Direct inhibition of the proteolytic activity of trypsin by heparin and dalteparin, used in concentrations typical for their clinical application, was detected. The half-maximum inhibition of the trypsin activity was achieved at 15.25±1.22 μg/mL for...
