Enoxaparin. A review of its pharmacology and clinical applications in the prevention and treatment of thromboembolic disorders.
Enoxaparin (PK 10169) belongs to the group of low molecular weight heparins which have a greater bioavailability and longer half-life than unfractionated heparin, permitting less frequent subcutaneous administration. In well controlled trials in surgical patients at high risk of deep venous thrombosis (DVT), enoxaparin has demonstrated prophylactic efficacy against venographically confirmed DVT at least equal to that observed with unfractionated heparin. Efficacy has also been demonstrated in patients at moderate risk and in limited investigations using 125I-fibrinogen scanning in nonsurgical patients at risk of DVT; in addition, enoxaparin appears to provide effective treatment of established DVT. In clinical studies, enoxaparin has also prevented coagulation of extracorporeal circulation, maintaining the patency of the circuit in patients undergoing haemodialysis. Thus, enoxaparin represents an effective alternative in the prophylaxis and treatment of thrombosis, with the convenience of less frequent administration than unfractionated heparin and the possible advantage of a lesser propensity for bleeding complications.
