Mechanism of action

Enoxaparin is derived from unfractionated heparin and works by potentiating antithrombin III, a natural anticoagulant, to inactivate clotting factors Xa and IIa. This prevents thrombin generation and fibrin clot formation. The low-molecular-weight formulation provides more predictable pharmacokinetics and predominantly anti-Xa activity compared to unfractionated heparin.
