What is LMWH?

Low-molecular-weight forms of heparin (LMWHs) can also act as anticoagulants which led to the isolation of enoxaparin (Lovenox <6000) the first LMWH. The LMWHs are heterogeneous compounds (one-third 1/3 the size of unfractionated heparin) produced by the chemical or enzymatic depolymerization of unfractionated heparin. Because they are free of some of the drawbacks associated with the polymer, they are replacing the use of heparin in many clinical situations
