NCIt definition : A synthetic low molecular weight heparin (LMWH) derived from porcine gut mucosa, with
anticoagulant activity. Upon administration, danaparoid 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).;
