[Parnaparin sodium - modern therapy options and prevention of venous thromboembolic complications]

Venous thromboembolic complications (VTEC) including pulmonary embolism and acute thrombosis of deep and superficial veins of the lower extremities are often observed in postoperative period. Low-molecular-weight heparin (LMWH) is a common remedy for prevention and treatment of VTEC due to high efficiency, safety, easy use and dosage. According to the modern literature data, LMWH is characterized by different effectiveness in relation to VTEC and risk of bleeding in patients after surgical and traumatological procedures, as well as in ones with severe forms of chronic venous diseases. However, their antithrombin activity varies significantly depending on mean molecular weight. The authors analyze LMWH action mechanism, pharmacokinetic and pharmacodynamic features of LMWH, in particular parnaparin sodium. Efficacy, safety and tolerability of this remedy for various forms of VTEC (superficial and deep vein thrombosis, thrombophlebitis, complicated forms of chronic venous diseases), its advantages for prevention of VTEC after various surgical and orthopedic interventions are considered.
