The interchangeability of low-molecular-weight heparins (LMWHs) has been the subject of discussion since these products were first introduced for the prophylaxis of deep vein thrombosis. Experimental evidence now exists to show that LMWHs differ from each other in a number of characteristics. Products have been differentiated on the basis of molecular weight and biologic properties, but only limited information derived from the clinical setting is available. Potency has been described on the basis of anti-Factor Xa activity, but at equivalent anti-Xa activities, the anti-Factor IIa activity of different products shows marked variations. At the relatively small doses used for the management of postsurgical deep vein thrombosis, the effect of these interproduct differences may be relatively minor, but as LMWHs are developed for therapeutic use at much higher doses, such differences may become clinically important. Variations in safety and efficacy reported in clinical trials of LMWHs may reflect the known differences in their molecular composition and pharmacologic properties.

Approximately 20 years ago a new family of antithrombotic compounds started to be investigated: the low-molecular weight heparins (LMWH). The rationale for their use was based on the evidence that the inhibition of the Factor Xa of blood coagulation was less marked than that of Factor IIa when using the LMWHs as compared to unfractioned heparin (HF). This particular mechanism of action was considered to be of advantage regarding the safety profile (the pro-haemorrhagic effect) compared to HF. Today we know that the real advantage of LMWHs is due to their high bioavailability which makes safe and reliable their subcutaneous administration without laboratory monitoring. The LMWHs are equally effective than HF for the treatment of acute Deep Vein Thrombosis. For the prophylaxis of Venous Thromboembolism, LMWHs are indicated as first choice in high-risk patients such as those undergoing major orthopaedic surgery. The future development of this family of drugs encompasses the launch of the pentasaccharide which is a pure anti-/Xa inhibitor.

Bemiparin is a low molecular weight heparin (LMWH) indicated for the acute treatment of deep vein thrombosis with or without pulmonary embolism, for the prophylaxis of venous thromboembolism in surgical and non-surgical patients and for the prevention of clotting in the extracorporeal circuit during hemodialysis. Due to its excellent pharmacological profile-the second-generation LMWH with the lowest molecular weight, the longest half-life and the highest anti-Factor Xa/anti-Factor IIa activity ratio-it can be safely used in special categories of patients (children, elderly, patients with renal impairment and congestive heart failure). Several studies demonstrated its safety and efficacy, while cost analyses show the economic benefits of bemiparin treatment as compared to other heparins. Recent evidences suggested the application of bemiparin even in the management of diabetic foot ulcers. The aim of this narrative review was to evaluate literature according to results coming from studies involving bemiparin administration in various clinical conditions.
