Mechanism of action

LMWH is derived from unfractionated heparin through chemical or enzymatic depolymerization, resulting in shorter chain lengths. This modification provides more predictable pharmacokinetics and preferential anti-Xa activity over anti-IIa activity compared to unfractionated heparin. LMWH is used for thromboprophylaxis and treatment of thromboembolic disorders.
