determine the coagulation time approximately every 4 hours in the early stages of treatment. When the drug is administered intermittently by intravenous injection, perform coagulation tests before each injection during the early stages of
12.1 Mechanism of Action Heparin interacts with the naturally occurring plasma protein, Antithrombin III, to induce a conformational change, which markedly enhances the serine protease activity of Antithrombin III, thereby inhibiting the activated coagulation factors involved in the clotting sequence, particu...

Mechanism of action The anticoagulation action of heparin depends on the presence of a specific serine protease inhibitor (serpin) of thrombin, antithrombin III, in normal blood. Heparin binds to antithrombin III and induces a conformational change that accelerates the interaction of antithrombin III wi...
