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 use… Weba. heparin and low molecular weight heparins b. heparin and warfarin with respect to mechanism of action, administration, time to onset of activity, method of monitoring, antidotes and use during pregnancy. 5.
