Dual Effect of Heparin and Low Molecular Weight Heparin on Cultured Smooth Muscle Cells.

Effect of unfractionated heparin and a low molecular weight heparin (enoxaparin) on coagulant activity of cultured human endothelial cells.

BACKGROUND AND OBJECTIVES Unfractionated heparin and low molecular weight heparins exert their anticoagulant effect by mobilizing tissue factor pathway inhibitor (TFPI) from the vascular endothelium into the blood circulation. We compared the influence of unfractionated heparin and enoxaparin on the anticoagulant function of cultured human endothelial cells. DESIGN AND METHODS Monolayers of h...

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...

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...

Preparation, properties and preclinical pharmacokinetics of low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle

Low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle (LMWH-ISL-SLN) was developed for injective application. The morphological observation, particle diameter and zeta potential of LMWH-ISL-SLN were characterized using transmission electron microscopy (TEM) and a Malvern Zetasizer. Its entrapment efficiency (EE) and drug loading (DL) were determined by ultracen...
