NCIt definition : The sodium salt form of danaparoid, a synthetic low molecular weight heparin (LMWH)
derived from porcine gut mucosa with anticoagulant activity. Danaparoid sodium binds
to antithrombin III and inhibits the activity of activated factor X (factor Xa) and,
to a lesser extent, activated factor II (thrombin) thereby preventing fibrin formation.
Compared to heparin, danaparoid sodium exhibits a much higher ratio of anti-factor
Xa activity to anti-factor IIa activity (22:1).;
