Mechanism of action

Dalteparin binds to and potentiates antithrombin III, a natural anticoagulant, leading to inactivation of activated factor X (Xa) and thrombin (factor IIa). This prevents the formation and extension of fibrin clots. LMWH agents have more predictable pharmacokinetics and longer half-lives compared to unfractionated heparin, allowing for subcutaneous dosing.
