Web1 jul. 1990 · After parenteral injection, heparin is removed from the blood via two mechanisms, saturable and non-saturable. The saturable mechanism represents clearance by the reticuloendothelial system and endothelial cells, to which heparin binds with a high affinity. The non-saturable mechanism is represented by renal excretion. In nature, heparin is a polymer of varying chain size. Unfractionated heparin (UFH) as a pharmaceutical is heparin that has not been fractionated to sequester the fraction of molecules with low molecular weight. In contrast, low-molecular-weight heparin (LMWH) has undergone fractionation for the purpose of making its pharmacodynamics more predictable. Often either UFH or LMWH can be u…
