Web12 dec. 2012 · Elimination is linear, with a mean residence time of over 7 h and total clearance of 0.9 L/h. The peak activity for the TFPI effect was earlier than the anti-Xa effect, at 1–2 h, and lasted for 6–12 h. Bemiparin thus has good antithrombotic activity and a better pharmacological profile than unfractionated heparin. WebLMWH is not removed from the plasma during hemodialysis or continuous veno-venous hemofiltration. In fact, the low-permeability membranes do not alter the anti-factor Xa activity in the plasma, although only a poor elimination of this heparin with high-permeability membranes is reported in the literature.

Use and Safety of Unfractionated Heparin for Anticoagulation …

Heparin and its low-molecular-weight derivatives (e.g., enoxaparin, dalteparin, tinzaparin) are effective in preventing deep vein thromboses and pulmonary emboli in people at risk, [22] [23] but no evidence indicates any one is more effective than the other in preventing mortality. Meer weergeven Heparin, also known as unfractionated heparin (UFH), is a medication and naturally occurring glycosaminoglycan.
