Witrynaheparin and LMWHs are discussed in the chapters that consider the evidence supporting antithrombotic therapy with these agents for the various clinical indications. This chapter will review the mechanisms of action of heparin and LMWHs, their pharmacokinetics, anticoagu-lant effects, side effects, and laboratory monitoring. The WitrynaLMWHs are defined as heparin salts having an average molecular weight of less than 8000 Da and for which at least 60% of all chains have a molecular weight less than 8000 Da. These are obtained by various methods of fractionation or depolymerisation of polymeric heparin. Heparin derived from natural sources, mainly porcine intestine or …
