Does low molecular weight heparin cross the placenta?
Standard heparin, an effective treatment for antepartum thromboembolic disease, is thought to be safe for the fetus since it does not cross the placenta. Recently, a number of low molecular weight heparins have been prepared which have been shown to produce less bleeding than standard heparin for an equivalent antithrombotic effect in experimental animals. These observations suggest that the low molecular weight heparins may also provide superior antithrombotic therapy in antepartum thromboembolic disease. However, it is not known whether the low molecular weight heparins cross the placenta. To determine this, we examined the pharmacokinetics of 125I-labelled standard heparin and a low molecular weight heparin, and their anticoagulant effects in mother and fetus, using a pregnant sheep model. Catheters were inserted into maternal and fetal femoral arteries at 108-119 d gestation (term: 147 d). 1-3 days later the mothers were given a bolus i.v. injection of 5000 anti-Xa units of 125I-labelled standard heparin or low molecular weight heparin, CY 222. Nine serial blood samples were collected over 4 h from both mother and fetus for measurements of radioactivity, anti-Xa activity (chromogenic) and activated partial thromboplastin times. When therapeutic levels of standard and CY 222 heparins were achieved in the mother, there was no detectable radioactivity or anticoagulant effect in the fetus. We conclude that standard heparin and the low molecular weight CY 222 do not cross the placenta in the pregnant sheep.
Is plavix low molecular heparin?
No, Plavix (clopidogrel) is not a low molecular weight heparin (LMWH). Plavix is an antiplatelet medication used to prevent blood clots by inhibiting platelet aggregation. In contrast, low molecular weight heparins are anticoagulants that work by inhibiting specific clotting factors in the blood to prevent clot formation. They are used for different medical purposes and have distinct mechanisms of action.
Can heparin cross placenta?
Heparin does not cross the placenta due to its large molecular size and negative charge. This characteristic makes it safe for use during pregnancy, as it does not affect the fetus. However, low molecular weight heparins (LMWHs), which are derived from heparin, also have limited placental transfer. Therefore, heparin is often preferred for anticoagulation in pregnant individuals.
What is heparin metabolized in?
Heparin is primarily metabolized in the liver and to a lesser extent in the reticuloendothelial system. The metabolism involves the action of heparinase enzymes, which break down heparin into smaller fragments. These fragments are then further processed and eliminated from the body, mainly through the kidneys. The metabolic process can vary based on the type of heparin used, such as unfractionated heparin or low molecular weight heparin.
What has the author Trevor David Power written?
Trevor David Power has written: 'Derivatization of low molecular weight heparin with polyethylene glycol monomethyl ether (MPEG)' -- subject(s): Heparin, Chemistry, Methyl ether
Who invented enoxaparin?
Enoxaparin was developed by the Sanofi-Aventis company. It was patented in 1987 and approved for medical use in 1993. Enoxaparin is a low molecular weight heparin that is used as an anticoagulant to prevent blood clot formation.
What is a molecule of low molecular weight capable of reacting with identical or different molecules of low molecular weight to form a polymer?
This is a catalyst.
What are the different types of heparin and how do they differ in terms of their effectiveness and side effects?
There are two main types of heparin: unfractionated heparin (UFH) and low molecular weight heparin (LMWH). UFH is more effective in treating acute conditions but requires close monitoring due to its higher risk of side effects like bleeding. LMWH is easier to use and has a lower risk of side effects, making it a preferred choice for long-term treatment.
What coagulation study is monitored for patient on heparin?
The coagulation study monitored for patients on heparin is the activated partial thromboplastin time (aPTT). This test measures the time it takes for blood to clot and helps ensure that the patient is within the therapeutic range for anticoagulation. Regular monitoring of aPTT is essential to prevent complications such as bleeding or thrombosis. For low-molecular-weight heparin, anti-factor Xa levels may also be monitored.
Density of low molecular weight polyisobutylene?
The density of low molecular weight polyisobutylene (PIB) typically ranges from 0.87 to 0.92 g/cm3. The exact value may vary based on factors such as molecular weight and purity of the material. It is a generally low-density material.
