Description

Ardeparin, marketed under the US trade name Normiflo, is a low molecular weight heparin (LMWH) anticoagulant used for the prevention of postoperative venous thrombosis. Ardeparin is derived via peroxide degradation of heparin extracted from porcine intestinal mucosa. Its molecular weight ranges from 2000 to 15,000 with an average molecular weight of 5500 to 6500. Normiflo was withdrawn from the US market in March 2000.

Pharmacology

Indication

For prevention of deep vein thrombosis, which may result in pulmonary embolism, following knee surgery.

Pharmacodynamics

Ardeparin, an anticoagulant, is a fractionated heparin. It acts at multiple sites in the normal coagulation system to inhibit reactions that lead to the clotting of blood and the formation of fibrin clots both in vitro and in vivo.

Mechanism of action

Ardeparin binds to antithrombin III, accelerating its activity in inactivating factor Xa and thrombin, thereby inhibiting thrombosis. Ardeparin also binds to heparin cofactor II, inhibiting thrombin. Ardeparin does not effect prothrombin time (PT) assays and may prolong activated partial thromboplastin time (APTT). Ardeparin has double the anti-factor Xa activity versus anti-factor IIa activity, compared to unfractionated heparin which has approximately equal anti-factor Xa activity and anti-factor IIa activity.
